This is an appeal from a judgment of civil contempt. Appellant is an attorney. She was before the trial court representing one Carlos Aquino, who was scheduled to stand trial on a charge of rape. On the Commonwealth’s petition, the trial court granted appellant immunity from the use against her of her testimony disclosing “any information she may have regarding the whereabouts of the ... Defendant, Carlos Aquino, and any information she may have on how to locate the Defendant Aquino.” N.T. 6/27/83 at 19. When the court ordered appellant to provide this information, appellant declined to do so on the grounds that the court lacked jurisdiction to compel her testimony; that the grant of immunity did not effectively protect her rights under the Fifth Amendment; and that the information she had been ordered to disclose was protected by the attorney-client privilege. N.T. 6/27/83 at 23-24. The court then found appellant guilty of civil contempt and ordered her to pay a fine of $100 a day until she complied with the *320court’s order. On appeal, appellant renews her arguments on jurisdiction and the attorney-client privilege. She also argues that she was entitled to a hearing on her claim, made incident to her request to the trial court for a stay, that she was being selectively prosecuted. We hold that the information appellant was ordered to disclose was protected by the attorney-client privilege. The order of the trial court is therefore reversed. We find it unnecessary to decide the issues raised by appellant’s arguments on jurisdiction and selective prosecution.
Appellant’s client, Carlos Aquino, was scheduled to stand trial on April 7, 1983, on a charge of rape. When Aquino did not appear for trial, the Commonwealth moved the trial court to compel appellant to “disclose the address and telephone number of the Defendant.” N.T. 4/7/83 at 2.
The Commonwealth offered no testimony in support of its motion. However, the assistant district attorney did make various statements to the trial court, as follows.
According to the assistant district attorney: Aquino last appeared before the trial court on January 19, 1983, when he was admitted to bail, and gave his address as 2941 Kensington Avenue, Philadelphia. N.T. 4/7/83 at 4. On February 9 a federal warrant was issued for his arrest. Id. at 5. The federal authorities went to the Kensington Avenue address and spoke with “a man by the name of Girardo Tempkin, who said the man [Aquino] had not stayed there since Christmas, and he had been in court since [sic] on January 19, 1983 with his attorney.” Id. at 6.
The assistant district attorney continued:
Ms. Maguigan [appellant] had been in contact with Girardo Tempkin, had spoken with him and she said she did not know where he was and was trying to locate him through Girardo Tempkin at this address, through the Kensington Avenue address. We don’t know and purportedly Ms. Maguigan does not know either.
N.T. 4/7/83 at 6.
*321This statement is not clear to us. Our interpretation of it is that when the federal authorities spoke to Tempkin, he told them that appellant had told him that she did not know where Aquino was and was looking for him.
The assistant district attorney went on to say: On February 19 and 22, 1983, “telephone records [sic] [were] intercepted” from Aquino’s brother’s residence in Milwaukee “to an address in Gladwynne.” Id. at 6. Aquino had been extradited from Milwaukee on the charge of rape. Id. On February 23 a call was made from a telephone booth in Milwaukee to appellant’s office. The call was charged to Aquino’s brother’s home telephone number, and was a seven-minute call. Id. at 7. On March 15 “Emigration [sic] officials” went to the Gladwynne address and were told that Aquino had never lived there, but on March 28 they returned and found that in fact he had been living there but had left three weeks ago. Id.
Finally, the assistant district attorney said:
The problem here is that [appellant] two weeks ago told me outside the courtroom in City Hall that despite the fact that I had several conversations with her regarding [Aquino’s] whereabouts being completely unknown, that she was ready to try the [rape] case and [Aquino] would be present and when I asked, Where is he; do you know, she said, I can’t tell you that.
Id. at 7-8.
This statement was contradicted by appellant. After hearing argument by respective counsel, the trial court asked appellant, “Are you ready to go to trial?”, to which she replied:
No sir. And one thing I would like to make clear is that I did not two weeks ago tell Ms. McDonough [the assistant district attorney] that I would produce my client today and that I knew where he was. She asked me if I could tell her where he was and I told her that I would not and she said, Let me ask you this, are you ready for trial? I said that as far as I am concerned I was ready since January. We were both in [Room] 625 and we got the *322first date the Court would give us. That was the extent of my representations to her. She has not called me to say, Do you object to having my witnesses on call? Id. at 21-22.
The contradiction between the assistant district attorney’s and appellant’s statements remains unresolved, for the trial court has made no findings of fact — we assume because no testimony was presented to it. Instead, immediately after appellant’s statement, the court indicated that it wished further argument, and a schedule for the submission of briefs was set. Id. at 22-23.
The further argument thus requested by the trial court was heard on April 13, 1983. During the proceeding on April 7, which we have just described in some detail, it was evident that the information sought from appellant was limited to her client Aquino’s address and telephone number. Thus at one point the trial court said to appellant’s counsel:
I assume we are proceeding under the assumption that [appellant] knows the Defendant’s [Aquino’s] address. I’m not expecting you to answer, but because if she didn’t know it, this whole thing was a futile exercise. So we’ll go ahead on that basis.
N.T. 4/7/83 at 16.
Shortly thereafter, the assistant district attorney said:
The question is the Defendant’s address....
Id. at 17.
And:
We are not asking [appellant] to tell us how to find [defendant] or anything. We have a right to know. This court has a right to know where he is, if she knows, and that’s all. We are not asking what communications he has had with her, anything he said with regard to where he has been hiding____ We are merely asking is there an address, if she knows his address and the Court deserves to know that.
Id. at 19-20.
*323At the further argument on April 13, however, the scope of the inquiry broadened, the trial court asking “whether [appellant] knows the whereabouts of the Defendant.” N.T. 4/13/83 at 2. Counsel for appellant responded that this question was “materially different than the question that was posed at the hearing [on April 7], does she know the address and phone number of the Defendant.” Id. When the court said, “Essentially, that’s what I want to know,” id., counsel replied, “She does not know the address and phone number of the Defendant,” id. at 2. After further colloquy, counsel said:
... I can represent to the Court that during the course of what we consider to be an attorney-client conversation, as a result of that conversation, [appellant] has some general information about the possible whereabouts of the Defendant, and I put it that way because there is a difference between that and the address issue.
Id. -at 3.
The court found this representation unsatisfactory, and, stating that “there is nothing in the client-counsel, attorney relationship that makes that information free from discovery,” id. at 4-5, found appellant in contempt and fined her $100 a day until she disclosed the information, id. at 6.
Upon appellant’s petition for a stay pending appeal, this court, by order dated April 26, 1983, stayed the order of contempt. On the Commonwealth’s application for remand so that it could present a petition asking the trial court to grant appellant immunity, this court, by order dated May 13, 1983, vacated the order of contempt and remanded the matter to the trial court.
On June 27, 1983, the Commonwealth’s petition asking that appellant be granted immunity came before the trial court. The petition alleged, inter alia, that “the Commonwealth believes that [appellant] has some information regarding [Aquino’s] whereabouts and wishes to question [appellant] in that regard,” Petition, para. 1, and that “information regarding [Aquino’s] whereabouts” was necessary “so that his continuing crime as a fugitive may be *324terminated,” and he “can be brought to trial for rape”, id., para. 2(a), (b). With its petition the Commonwealth submitted a form of order providing in part that appellant be ordered to
disclose to this Court and the District Attorney’s Office any information she may have regarding the whereabouts of the ... Defendant, Carlos Aquino, and any information she may have on how to locate the defendant Aquino.
Again, no testimony was offered by the Commonwealth, only argument being heard. At the conclusion of argument, the trial court entered its order in the form submitted by the Commonwealth. N.T. 6/27/83 at 19-20. The court then directed appellant to testify forthwith in accordance with its order. Id. at 23. Appellant declined on the grounds that the court lacked jurisdiction to compel her testimony; that the grant of immunity did not effectively protect her rights under the Fifth Amendment; and that the information she had been ordered to disclose was protected by the attorney-client privilege. Id. at 23-24. The court thereupon found appellant guilty of civil contempt and ordered her to pay a fine of $100 a day until she complied with the court’s order. On appellant’s application, we granted a stay pending disposition of this appeal, which we ordered expedited.

Appellant argues that since no proceeding was pending before the trial court, the court had no jurisdiction to compel her testimony.
We agree with appellant that a court has no power to compel testimony where no proceeding is pending before the court. “The essence of a subpoena’s function is to aid the court in the resolution of litigation, so that if there is no formal proceeding pending before the court there can be no legitimate reason to issue a subpoena.” Commonwealth v. Polak, 438 Pa. 67, 69, 263 A.2d 354, 356 (1970). From this it follows that a court has no power to compel testimony by granting immunity, absent a pending proceeding. See also *325Commonwealth v. DeJohn, 486 Pa. 32, 41 n. 5, 403 A.2d 1283, 287 n. 5 (1979).
The question here, however, is whether there was a proceeding pending before the trial court when appellant was granted immunity and ordered to testify. In appellant’s view, there was not: Aquino’s trial on the charge of rape was not “pending” but instead, never got started; and while criminal charges may someday be brought against Aquino because of his failure to appear for trial, so far as appears no such charges have been brought yet, and therefore neither can they be described as “pending.” However, while no charges have been brought against Aquino for his failure to appear for trial, charges have been brought against him for rape. Perhaps it may not be said that the trial on those charges was “pending” before the court. But what about the charges themselves?
The issue has been obscured, however, by what seem to be inconsistent positions taken, by the Commonwealth.. On the one hand, the Commonwealth distinguishes Polak and DeJohn on the ground that “these cases involved only ongoing investigations whereas the instant case involves a pending prosecution within the court’s jurisdiction.” Brief for Commonwealth at 12 n. 11. (Commonwealth’s emphasis.) This seems to argue that the trial court had jurisdiction because of the fact that appellant’s client, Aquino, had been charged with rape and directed to appear for trial. And consistent with this argument, the Commonwealth alleged in its petition that appellant be granted immunity that “[t]his information \i.e., 'information regarding [Aquino’s] whereabouts’] is ... essential so that defendant can be brought to trial for rape.” Petition, para. 2(b). On the other hand, the Commonwealth also alleged in its petition, as the first reason why appellant should be granted immunity, that “[i]t is necessary for the Commonwealth to obtain information regarding [Aquino’s] whereabouts so that his continuing crime as a fugitive may be terminated.” Id. paragraph 2(a). This seems to argue that because Aquino was committing a crime, the trial court had jurisdiction to *326compel appellant’s testimony so that the Commonwealth could investigate and apprehend him for that crime.
The trial court itself was of the view that its jurisdiction derived from the Immunity Act. Slip op. at 20-21. Section (a) of the Act provides:
(a) General rule. — Immunity orders shall be available under this section in all proceedings before:
(1) Courts
(2) Grand juries
(3) Investigating grand juries
(4) The minor judiciary or coroners.
42 Pa.C.S.A. § 5947(a).
The trial court held that the rape charges against Aquino were “proceedings before [the court].” Id. at 21. The court did not discuss the Commonwealth’s apparent invocation of its jurisdiction to enable an investigation of Aquino for. his continuing crime as a fugitive.
It seems clear that if the claim were that appellant had information relevant to whether Aquino had committed the rape, the trial court would have had jurisdiction to grant her immunity so that the Commonwealth might call her as a witness against Aquino. But it is not so clear that the Immunity Act was intended to extend to a situation where the information sought is ir-relevant to whether the rape was committed.
In saying this, we recognize that evidence that Aquino had not appeared for trial might be relevant as tending to prove consciousness of guilt and hence guilt itself. See generally McCormick on Evidence 655 (2d ed. 1972). But appellant’s testimony was not sought to prove that Aquino had fled, but to prove where he had fled. In its brief, the Commonwealth leaves no doubt on this point, stating that “[ajppellant has not been asked why her client fled, but where he may be found.” Brief for Commonwealth at 6-7 n. 8. It does not appear how such evidence could be relevant at trial. Indeed, when at oral argument counsel for appellant asserted that the Commonwealth would try to *327use appellant’s testimony against her client at trial, counsel for the Commonwealth denied the assertion, saying that the testimony was sought only so that Aquino could be brought to trial; and in its Supplemental Brief, at 2, the Commonwealth states that the trial court ordered áppellant to testify so that the court could “proceed with the pending prosecution.” It may be that the Immunity Act by its reference to immunity orders “in all proceedings before” a court permits an attempt to secure testimony that is irrelevant to proof in a given proceeding of the defendant’s guilt, but we have not been cited to, nor are we aware of, any precedent supporting such an extension of the Act. So far as we know, the use made of the Immunity Act in this case is unprecedented.
Thus we find ourselves unpersuaded by the reasoning either of appellant, the Commonwealth, or the trial court. If we had to decide the issue of the trial court’s jurisdiction, then of course we would. But, for reasons that will appear, we have concluded that in any event the information sought from appellant was protected by the attorney-client privilege. In these circumstances we believe the better way for us to proceed is to refrain from deciding an issue both difficult and novel, and so far as we can tell, unlikely to arise again. Instead, we shall simply assume that the trial court did have jurisdiction, and decide the appeal on its merits.

(a)
“The notion that the loyalty owed by the lawyer to his client disables him from being a witness in his client’s case is deep-rooted in Roman law,” McCormick, supra at 175 (footnote omitted), and the attorney-client privilege, “of which we find the first trace in Elizabeth’s time,” id., is the oldest of the privileges protecting confidential communications. 8 Wigmore, Evidence §§ 2292 at 542 (McNaughton rev. 1961). See also Cohen v. Jenkintown Cab Company, 238 Pa.Super. 456, 357 A.2d 689 (1976). Wigmore states the privilege as follows:
*328Where legal advice of any kind is ... sought from a professional legal adviser in his capacity as such, ... the communications relating to that purpose, ... made in confidence ... by the client, ... are at his instance permanently protected ... from disclosure by himself or by the legal adviser, ... except the protection be waived.
Wigmore, supra at 554.
The original theory by which the privilege was explained was that on his oath and honor, the attorney’s “first duty ... [was] to keep the secrets of his clients.” Wigmore § 2290 at 543 (citation omitted). In the early 1700’s, however, a “new theory began to appear [which] looked to the necessity of providing subjectively for the client’s freedom of apprehension in consulting his legal adviser.” Id. (emphasis in original). The older theory “struggled along for some time by the side of the newer one, like two powerful streams debauching into the same channel.” Id. at 543-544. But since the late 1700’s the privilege has been grounded on the necessity of promoting freedom of communication between attorney and client by allaying the client’s fear that the attorney will be compelled to disclose a confidence. Id. at 545. This court has repeatedly explained the privilege in these terms. Commonwealth v. Hutchinson, 290 Pa.Super. 254, 434 A.2d 740 (1981) (purpose of privilege to foster full communication between attorney and client); Brennan v. Brennan, 281 Pa.Super. 362, 422 A.2d 510 (1980) (“[T]he privilege is not concerned with prejudice, the ascertainment of truth, or the reliability of attorney-client communications, but only to foster a confidence between an advocate and his client that will lead to a trusting and open dialogue.”) (citation omitted); Cohen v. Jenkintown Cab Company, supra (purpose of privilege to enable client to place unrestricted and unbounded confidence in attorney). See also Estate of Kofsky, 487 Pa. 473, 409 A.2d 1358 (1980).
As is true of other aspects of the law, such as the right to be free of unreasonable searches and seizures, or the privilege against self-incrimination, the attorney-client privilege *329is sometimes characterized as protecting someone who has violated the law. But this reveals a fundamental misconception. The privilege is to protect, not the guilty, but the administration of justice. “[T]he theory [is] that claims and disputes which lead to litigation can most justly and expeditiously be handled by practiced experts, namely lawyers, and that such experts can act effectively only if they are fully advised of the facts by the parties whom they represent.... The proposition is that the detriment to justice from a power to shut off inquiry to pertinent facts in court, will be outweighed by the benefits to justice (not to the client) from a franker disclosure in the lawyer’s office.” McCormick, supra at 175. Thus, our Supreme Court has stated that “the damage to the administration of justice occurs when the sanctity of the confidence is improvidently violated, not when the evidence is given substantive consideration.” Estate of Kofsky, supra, 487 Pa. at 482, 409 A.2d at 1362.
In Pennsylvania the attorney-client privilege has as to criminal cases been codified in 42 Pa.C.S.A. § 5916.1 It provides:
In a criminal proceeding counsel shall not be competent or permitted to testify to confidential communications made to him by his client, nor shall the client be compelled to disclose the same unless in either case this privilege is waived upon the trial by the client
Similarly, Canon 4 of the Code of Professional Responsibility2 provides that “[a] Lawyer Should Preserve the Confidences and Secrets of a Client,” and the Code’s Disciplinary *330Rule 4-101, entitled “Preservation of Confidences and Secrets of a Client,” includes the following provisions:
(B) Except when permitted under DR 4-101(C), a lawyer shall not knowingly:
(1) Reveal a confidence or secret of his client, including his identity.
(2) Use a confidence or secret of his client to the disadvantage of the client.
(C) A lawyer may reveal:
(1) Confidences or secrets with the consent of the client ..., but only after a full disclosure____
(2) Confidences or secrets when permitted under Disciplinary Rules or required by court.
(3) The intention of his client to commit a crime and the information necessary to prevent the crime.
Ethical Consideration 4-4 points out that Canon 4 and the common law privilege are not identical:
The attorney-client privilege is more limited than the ethical obligation of a lawyer to guard the confidences and secrets of his client. This ethical precept, unlike the evidentiary privilege, exists without regard to the nature or source of information or the fact that others share the knowledge.
Even so, “in any analysis of the attorney-client privilege, we must recognize that our Code of Professional Responsibility provides strong support for the concept of a legally protected confidentiality for client attorney discourse.” Brennan v. Brennan, supra 281 Pa.Super. at 370, 422 A.2d at 514.
(b)
In applying these general considerations to this case, it is essential to note exactly what the Commonwealth seeks from appellant, and what the trial court ordered her to disclose. The Commonwealth has characterized the trial court’s order as a “carefully circumscribed inquiry,” Supplemental Brief for Commonwealth at 3, and in support of the order has cited textual and decisional authority for the proposition that the attorney-client privilege does not bar *331disclosure of the client’s address. Brief for Commonwealth at 6-9. But it is immediately apparent that this is not an “address case”; the trial court’s inquiry is far broader.
As we have noted in stating the facts of the case: The case started as an “address case.” At the first hearing, the Commonwealth’s motion was “to [cjompel defense counsel [appellant] to disclose the address and telephone number of the Defendant,” N.T. 4/7/83 at 2, and the assistant district attorney stated “[t]he question is the Defendant’s address____,” id. at 17, going on to say, “We are not asking [appellant] to tell us how to find him or anything---- We are merely, asking is there an address, if she knows his address and the Court deserves to have that,” id. at 19-20. But at the second hearing, the inquiry became far broader. Then the.trial court asked “whether [appellant] knows the whereabouts of the Defendant.” N.T. 4/13/83 at 2. Appellant’s counsel at once pointed out that this inquiry was “materially different than the question that was posed” at the first hearing. Id. As to that question, he said, “[appellant] does not know the address and phone number of the Defendant.” Id. The trial court, nevertheless, held appellant in contempt. Finally, at the third hearing, the inquiry became still broader. Then the Commonwealth submitted, and the trial court issued, an order requiring appellant to
disclose to this Court and the District Attorney’s Office any information she may have regarding the whereabouts of the ... Defendant, Carlos Aquino, and any information she may have on how to locate the defendant Aquino.
N.T. 6/27/83 at 19.
This order is not, as the Commonwealth characterizes it, “carefully circumscribed.” To the contrary, it is general in the extreme, leaving undefined whatever limits there may be on the questions that the Commonwealth may ask appellant. Suppose, for example, that Aquino at some point told appellant as his attorney that A, B, and C were witnesses to the crime, or otherwise knew something that appellant should look into as relevant to his defense. Under the trial court’s order would appellant have to disclose the identity *332and whereabouts of A, B, and C? It is clear that she would. For if A, B, and C knew about the crime, they may also know where Aquino is. If an attorney doesn’t know where her client is, a good way to start looking for him is to ask his friends if they know where he is. Thus, appellant’s knowledge regarding A, B, and C would be “information [that she had] on how to locate the defendant Aquino.” Indeed, that this would be true has already been shown by the Commonwealth’s own statements to the trial court. At the first hearing the assistant district attorney represented to the court that she had learned from federal authorities that in February 1983, about two months before the date set for Aquino’s trial, appellant “had spoken with [one Girardo Tempkin] and she said she did not know where [Aquino] was and was trying to locate him____” N.T. 4/7/83 at 6. Other, similar, examples of information that appellant might have acquired as Aquino’s attorney that would fit within the trial court’s order as information “on how to locate” Aquino may readily be imagined.
In its brief as amicus curiae, at 19-20 n. 18, the Defender Association of Philadelphia says that by the trial court’s order, appellant would be “effectively converted into an investigative arm of the prosecution”. This is not an overstatement. Neither the trial court nor the Commonwealth has cited any authority upholding so sweeping an order against a plea of the attorney-client privilege. Nor should we expect to find any. For to uphold so sweeping an order would not “foster” but imperil “the confidence between an advocate and his client,” the “trusting and open dialogue,” that the privilege is intended to ensure. Brennan v. Brennan, supra. We therefore conclude that the trial court’s order holding appellant in contempt must be vacated.
The Commonwealth has responded to the Defender Association’s amicus brief by saying that it “must be noted that appellant never raised this claim in the court below or in his brief to their Court. Certainly an amicus brief cannot 'preserve’ a point for relief that the litigant herself has never pursued.” Supplemental Brief for Commonwealth at *3332. This argument has no merit. As we have already noted, when the inquiry broadened from whether appellant knew Aquino’s address and telephone number to whether she knew “the whereabouts of [Aquino]”, appellant’s counsel at once pointed out that the second inquiry was “materially different” than the first,- going on to answer the first, narrow, inquiry, while refusing to answer the second, broadened, one. N.T. 4/13/83 at 2, 4-5. In addition, when arguing that the trial court had no power to grant appellant immunity, appellant’s counsel said, “[S]o what you have here in the absence of some ongoing criminal case is the same kind of fishing expedition that the Supreme Court condemned in [Commonwealth v. Polak, supra],” N.T. 6/27/83 at 10, to which the court responded that in its opinion “the powers of granting immunity are far broader under [the Immunity Act] than they were prior thereto, “id. In appellant’s brief to this court the first question stated, under Statement of Questions Involved, is, “Does the attorney-client privilege protect an attorney from revealing information on the whereabouts of his or her client?” Brief for Appellant at 2. And in arguing that the trial court’s order violates the attorney-client privilege, appellant characterizes the order as one that “will allow fishing expeditions by prosecutors and trial courts for information that, as here, can be used as evidence against the client in the same or different criminal proceedings,” id. at 14, adding that “[t]he problem of establishing a workable attorney-client relationship in criminal cases is difficult enough; no further problems, such as those that would be created by this kind of intrusion, should be countenanced,” id. The record is therefore clear that, contrary to the Commonwealth, appellant has argued the issue of the trial court’s order being overbroad both to the trial court and to this court. Appellant’s characterization of the order is at least as critical as amicus’s; the only difference of substance between appellant’s argument and amicus’s is that amicus addresses only the issue of overbreadth and not also, as appellant does, the issue of jurisdiction and selective prosecution.
*334(c)
We might conclude with what we have just said. Since the trial court’s order holding appellant in contempt must be vacated, appellant’s argument that she was entitled to a hearing on her claim of selective prosecution is moot; and in strict logic, it is unnecessary to assign any further reason for vacating the trial court’s order beyond the reasons we have given. In the interests of complete discussion, however, we shall make some further comment. For even if the trial court’s order were not overbroad, we should still be obliged to vacate it.
The attorney-client privilege is not absolute. It may be waived by the client; in some circumstances it may be that the client’s death will end the privilege, or so at least McCormick argues, McCormick, supra at 199 (“[Disclosure] could not in any substantial degree lessen the encouragement for open disclosure which is the purpose of the privilege”); and “[s]ince the policy of the privilege is that of promoting the administration of justice, it would be a perversion of the (privilege to extend it to the client who seeks advice to aid him in carrying out an illegal or fraudulent scheme,” McCormick, supra at 199. And see Brennan v. Brennan, supra privilege not a bar where legal advice sought to assist in crime or fraud); Cohen v. Jenkintown Cab Co., supra (privilege not a bar where client’s rights or interest cannot be adversely affected by disclosure). Here, the Commonwealth argues that to uphold the attorney-client privilege would be a perversion of it. Citing authority that “bail-jumping” is “a continuing crime,” the Commonwealth argues that Aquino’s “defiance of lawful process is a continuing contempt of the court which is responsible for the case and there is an ongoing offense,” Brief for Commonwealth at 6 (footnote omitted), and that “the attorney-client privilege does not protect clients for blatantly defying court orders and frustrating the orderly administration of justice,” id. at 7 (citation omitted).
The fallacy in this argument is that it overlooks the requirement that “the party seeking disclosure has the *335burden of establishing a prima facie case that the attorney was used to promote an intended or continuing fraudulent or criminal activity.” Brennan v. Brennan, supra, 281 Pa.Superior Ct. at 372, 422 A.2d at 515 (emphasis in original), citing Nadler v. Warner Company, 321 Pa. 139, 143-144, 184 A. 3, 5 (1936) (when advice of counsel sought in commission of crime or fraud, communications not confidential, but before ordering disclosure court must be satisfied that proposed evidence of wrongful purpose is sufficient to go to jury), and In re Westinghouse Electric Corporation Uranium Contracts, 76 F.R.D. 47 (D.C.W.Pa.1977). In this regard, perhaps the leading case is Clark v. United States, 289 U.S. 1, 53 S.Ct. 465, 77 L.Ed. 993 (1933), where Justice CARDOZO explained the requirement of a prima facie case: “There must be a showing of a prima facie case sufficient to satisfy the judge that the light should be let in____ It is obvious that it would be absurd to say that the privilege could be got rid of merely by making a charge of fraud____ To drive the privilege away, there must be something to give colour to the charge. A privilege surviving until the relation is abused and vanishing when abuse is shown to the satisfaction of the judge has been found to be a workable technique for the protection of the confidences of client and attorney.” Id. at 14-16, 53 S.Ct. at 469-470 (citations omitted). And see In re Special September 1978 Grand Jury, 640 F.2d 49 (7th Cir.1980) (attorney-client privilege overcome by prima facie showing of fraud); United States v. Calvert, 523 F.2d 895 (8th Cir.1975), cert. denied, 424 U.S. 911, 96 S.Ct. 1106, 47 L.Ed.2d 314 (1976) (confidential communications from client to attorney not privileged if court concludes evidence warrants finding that communications were made for purpose of obtaining aid in commission of criminal acts.); Pollock v. United States, 202 F.2d 281. (5th Cir.1953, cert. denied 345 U.S. 993, 73 S.Ct. 1133, 97 L.Ed. 1401 (1953) (communication not privileged where made in furtherance of crime of which client was charged and evidence giving colour to charge had been introduced); United States v. Bob, 106 F.2d 37, 40 (2nd Cir.1939), cert. denied 308 U.S. 589, 60 S.Ct. 115, 84 *336L.Ed. 493 (1939) (“There must, of course, be first established a prima facie case; the mere assertion of an intended crime or fraud is not enough to release the attorney.”) (citation omitted); In re Selser, 15 N.J. 393, 105 A.2d 395 (1954) (court must find that sufficient evidence, aside from communication, has been introduced to warrant finding that legal advice was sought to enable client to commit crime or tort).
Here, the Commonwealth failed to make any showing whatever, much less a prima facie case sufficient to go to a jury, that appellant “was used to promote an intended or continuing fraudulent or criminal activity.” Brennan v. Brennan, supra 281 Pa.Super. at 372, 422 A.2d at 515. As already noted, the Commonwealth offered no testimony, the assistant district attorney making only various unsworn representations — almost all of which were hearsay statements of what federal authorities had said.
But if for the sake of discussion we regard the assistant district attorney’s representations as admissible evidence, still the record is deficient in several key respects. It does not disclose when Aquino formed his intention to jump bail — whether before or after he moved; or whether he even communicated his intention to jump bail to appellant; or if he ever did communicate his intention to appellant, when he did, or what appellant advised him. In short, nothing suggests that appellant was in any way used to promote any criminal activity, or, indeed, that she has done anything in any sense either unethical or wrong.
At oral argument the Commonwealth emphasized appellant’s own statement to the trial court, but we fail to see how this helps the Commonwealth. We have quoted in full both the assistant district attorney’s statement of what appellant said, and appellant’s own statement, above, and will only summarize them now. According to the assistant district attorney: Two weeks before the date set for trial, Aquino’s “whereabouts [were] completely unknown.” N.T. 4/7/83 at 8. Appellant told her “that she was ready to try the case and [Aquino] would be present and when I asked, *337Where is he; do you know, she said, I can’t tell you that.” Id. According to appellant: “I did not two weeks ago tell [the assistant district attorney] that I would produce my client today or that I knew where he was. She asked me if I would tell her where he was and I told her I would not and she said, Let me ask you this, are you ready for trial? I said that as far as I am concerned I was ready since January.” Id. at 21-22. As we have observed, the trial court made no findings either reconciling or choosing between these to some extent contradictory statements. But in any event, nothing in the record suggests that when appellant said whatever she said, she had any reason to suppose that Aquino had jumped, or intended to jump, bail, or that she had done anything to promote any such criminal activity.
The conclusion is therefore inescapable that the Commonwealth failed to meet its burden of proof. As Justice CARDOZO explained, “To drive the [attorney-client] privilege away, there must be something to give colour to the charge [that the privilege has been fraudulently used].” Clark v. United States, supra. Here, nothing does give colour to the charge.3
One further comment may be made. In Brennan v. Brennan, supra, we noted two exceptions to the privilege: where “the attorney was used to promote an intended or continuing fraudulent or criminal activity”, and where “the interests of justice may be frustrated by the exercise of the privilege”. 281 Pa.Super. at 372, 422 A.2d at 515. The question therefore arises whether the record discloses that this second exception has been met.
*338Wé did not have occasion in Brennan to consider to what extent the two exceptions — fraud or crime, and interests of justice — were different. However, the single case cited with reference to the interests of justice exception was Cohen v. Jenkintown Cab Company, supra. In Cohen the issue was whether to require the disclosure of a deceased cabdriver’s communications to his attorney that he was the driver of a cab that had struck Cohen, a pedestrian. It was shown that the communications were relevant to establish the cabdriver’s involvement; that the action was against the cab company and not the driver or his estate; that the cabdriver was deceased and had left no estate that could be joined as a third-party defendant; and that the communications did not contain scandalous and impertinent matter that would blacken the memory of the cabdriver. In reaching our decision in Cohen, we cited a passage from Hamilton v. Neel, 7 Watts 517, 521 (1838), where our Supreme Court noted an exception to the attorney-client privilege:
But where it is impossible, that the rights or the interests of the client can be affected by the witness’s giving evidence of what came to his knowledge by his having been counsel and acted at the time as attorney or counsel at law, the rule has no application whatever, because the reason of it does not exist.
(emphasis added in Cohen, 238 Pa.Super. at 462, 357 A.2d at 692).
Based on the authority of Hamilton, we observed:
Thus, in Pennsylvania the privilege does not bar testimony of an attorney which reveals the substance of a confidential communication where, in context, the client’s rights or interest cannot be adversely affected thereby. Id.
We then held that “on balance, ... the interests of justice required the disclosure of [the] communications” in question, id., going on to say:
The [attorney-client] privilege exists only to aid in the administration of justice, and when it is shown that the interests of the administration of justice can only be *339frustrated by the exercise of the privilege, the trial judge may require that the communication be disclosed [citations omitted]. In making this determination, however, the trial court should resolve all doubt in favor of non-disclosure, so that a client should not be chagrined to learn that the confidences that he conveyed to his attorney have been revealed to his detriment and without his consent, [footnote omitted].
Id., 238 Pa.Superior Ct. at 464-65, 357 A.2d at 692-94.
It therefore appears that, whatever its exact dimensions, the interests of justice exception is very narrow, extending to such situations as those in which “the client’s rights or interests cannot be adversely affected [by disclosure].” Indeed, it is evident that this must be so. Otherwise the exception would devour the rule. For the interests of justice are always “frustrated” by the exercise of the privilege in the sense that the prosecutor is unable to learn from the attorney what he would like to learn. As already discussed, however, a true understanding of the interests of justice carries with it an appreciation of the fact that free communication between the client and attorney must be fostered; and as we have said, in Cohen and again in Brennan, that means that any exception to the privilege must be narrowly confined, all doubts being resolved in favor of non-disclosure.
Here, the Commonwealth failed to make out a prima facie case within the interests of justice exception, for plainly, this is not a case in which “the client’s rights or interests [would not] be adversely affected” by requiring appellant as his attorney to disclose the information sought by the prosecutor.
(d)
None of the authorities cited to us by the Commonwealth disturbs the foregoing conclusions — that the trial court’s order directing appellant to testify was overbroad, and that the Commonwealth failed to meet its burden of proof. It may be useful, however, to discuss at least some of the *340Commonwealth’s citations, for while this may involve some repetition, it may make plainer what has already been said.
Some of the Commonwealth’s citations are not persuasive because they do not go to the point of overbreadth. For example, the Commonwealth cites McCormick for the proposition that “[t]he weight of authority denies the [attorney-client] privilege for ... such identifying facts about [the client] as his address____” McCormick, supra at 185-86 (footnote omitted). But this case is not an “address case.” Rather, appellant, by her counsel, stated that she did not know her client’s address, and the Commonwealth neither asserts nor has it shown that she did. The order here is not that appellant disclose Aquino’s address but that she disclose “any information she may have regarding the whereabouts of ... Aquino ... and any information she may have on how to locate” him. Thus, a case such as Dike v. Dike, 75 Wash.2d 1, 448 P.2d 490 (1968), cited by McCormick, and also by the Commonwealth, is not in point. In Dike, the attorney knew the client’s address, and was asked to disclose only that address. Similarly, In the Matter of Jacqueline F., 94 Misc.2d 96, 404 N.Y.S.2d 790 (1978), Jafarian-Kerman v. Jafarian-Kerman, 424 S.W.2d 333 (Mo.App.1967), and Falkenhainer v. Falkenhainer, 198 Misc. 29, 97 N.Y.S.2d 467 (1950), cited by the Commonwealth, are address cases. Jacqueline F. and Jafarian-Kerman, it may be added, are discussed in Brennan v. Brennan, supra.
Further in regard to the issue of overbreadth, it is instructive to consider United States v. Woodruff, 383 F.Supp. 696 (E.D.Pa.1974), also cited by the Commonwealth. There, the defendant failed to appear for trial, and the government, with a view to seeking an indictment against him for jumping bail, requested the district court to order the defendant’s attorney, a public defender, to answer questions
relating to whether or not he advised his client as to the time and place of the trial ... [and] whether or not his client responded and acknowledged that he understood the time and place of the trial.
*341383 F.Supp. at 696.
Holding that this information was not privileged, the district court said:
The communications here were not made with the purpose of securing legal advice or assistance with respect to the legal problem of the defendant. Moreover, the nature of the communications are such that the information is not incidental to or intertwined with the legal problem of the defendant. Finally, the form of the questions and the nature of the communications together insure that privileged communications will not be drawn with their scope____ Such, communications are non-legal in nature. Counsel is simply performing a notice function. [T]he fact that the questions proposed are specific and discrete, lead[s] us to conclude that the transmission of the information in that context is also outside the privilege.
Id. at 697-698 (emphasis added).
This decision supports not the Commonwealth but appellant. For appellant was not asked “specific and discrete” questions so limited in scope as to “insure that privileged communications [would] not be drawn within their scope.” Instead, as we have discussed, she was asked questions so Mwspecific and so unlimited as to insure — or at least make it very likely — that privileged conversations would be drawn within their scope.
By other citations the Commonwealth reveals its failure to recognize its duty to establish a prima facie case that to compel disclosure would be within an exception to the attorney-client privilege. Thus the Commonwealth asserts that Brennan v. Brennan, supra, “specifically supports the Court’s contempt order.” Brief for Commonwealth at 4. Quite the contrary is the case. In Brennan we reversed an order finding an attorney in contempt for refusing to disclose his client’s address. Quoting our statement that there was no evidence that the client was in violation of any proper order, the Commonwealth argues that here it appears that appellant’s client was in violation of a proper *342order — to appear for trial. According to the Commonwealth, it follows that here appellant was properly held in contempt. But this misses one of the principal points of Brennan, which, as already discussed, is that the party seeking disclosure has the burden of proof. In Brennan, this burden was not met because the party seeking disclosure did not show that there was any fraudulent or criminal activity or any frustration of the interests of justice (this being so for a variety of reasons, one of which was that it had not been shown that the client was in disobedience of any proper order). Here, the burden has not been met because, while it may be assumed that appellant’s client, Aquino, is engaged in criminal activity — having jumped bail — the Commonwealth has not shown that appellant was in any way used to promote that activity. It has only shown that Aquino did not appear for trial, and that appellant did not know his address or telephone number. So far as appears, Aquino jumped bail without telling or consulting appellant.
Brennan, moreover, is also relevant to the issue of overbreadth, and on that issue too it is against the Commonwealth. Brennan was an “address case”, for the attorney knew the client’s address and telephone number and was asked to disclose only that information and the name and address of the children’s school (Brennan was a child custody case). In deciding that on the particular facts even so limited an inquiry was in violation of the attorney-client privilege, we emphasized the policy underlying the privilege, stating that “the court should resolve all doubts in favor of non-disclosure, so that the client should not be chagrined to learn that the confidences that he conveyed to his attorney have been revealed to his detriment and without his consent. Cohen v. Jenkintown Cab Company, supra." 281 Pa.Super. at 372, 422 A.2d at 515 (emphasis in original). The Commonwealth’s citation of Brennan overlooks this aspect of our decision.
A similar observation may be made regarding the Commonwealth’s citation of Matter of Grand Jury Subpoenas Served Upon Field, 408 F.Supp. 1169 (S.D.N.Y.1976), and *343In re Stolar, 397 F.Supp. 520, 521 (S.D.N.Y.1975). In Field, while recognizing that the client’s address is not always privileged, the court held that in the circumstances, it was, and in Stolar, also, the court refused to require disclosure, holding that it was an abuse of process to issue a subpoena not to aid a grand jury in returning an indictment but to aid the F.B.I. in determining the whereabouts of a third party by questioning the client. The Commonwealth has argued that these cases implicitly hold that in circumstances other than those actually presented, the courts would have ordered disclosure. We do not find this argument helpful. The courts in fact did not order disclosure, and both opinions recognize the importance of the attorney-client privilege in fostering free communication between the client and attorney.
The Commonwealth has also cited In the Matter of John Doe, 117 Misc.2d 197, 456 N.Y.S.2d 312 (1982), and Matter of Jane Doe, 101 Misc.2d 388, 420 N.Y.S.2d 996 (1979), but we think both of these cases are best explained as involving the criminal or fraudulent purpose exception to the attorney-client privilege. In John Doe, the attorney refused to answer a grand jury’s questions about the whereabouts of his client, while at the same time arguing that the indictment against his client should be dismissed for denial of a speedy trial. The court was of the opinion that in the circumstances, to uphold the privilege “would aid and abet the advancement of an unlawful act.” 456 N.Y.S.2d at 315. Similarly, in Jane Doe, the court appears to have regarded the confidence as “received by [the] attorney in order to advance a criminal or fraudulent purpose.” 420 N.Y.S.2d at 999.
In concluding this part of our discussion, we readily acknowledge that general language may be found in some of the cases that at first reading may appear to support the Commonwealth, and also, that some of the cases are not readily reconciled. We are satisfied, however, that our conclusion is supported both by the better-reasoned cases and by sound considerations of principle.

*344CAVANAUGH, J., concurs in the result. MONTEMURO, J., files a concurring and dissenting opinion.. As to civil cases the privilege has been codified, in identical terms, in 42 Pa.C.S.A. § 5928.
. Adopted by the Supreme Court of Pennsylvania on February 27, 1974, effective February 27, 1974. We note that the American Bar Association’s Model Rules of Professional Conduct were adopted by the ABA House of Delegates on August 2, 1983. See 52 U.S. Law Week 1-27, August 16, 1983. The Model Rules have not been adopted, at least not yet, by the Pennsylvania Supreme Court. Even so, we find nothing in the Model Rules that would affect our holding in the present case.
. We note that in 2 Weinstein’s Evidence, § 503(d)(l)[01] at 503-71, it is said that although "[a] number of federal cases prior to the adoption of the federal rules [of evidence in 1975] had insisted upon a prima facie showing before the privilege was withdrawn, [t]he notes to [Supreme Court] Standard 503(d)(1) [the crime-fraud exception] specifically state that a preliminary finding is not required.” While this appears to be true, it is also true that Congress struck Standard 503. But even if Congress had adopted Standard 503, Brennan v. Brennan, supra, would continue to require Pennsylvania courts to impose the prima facie showing requirement.
