Is attorney-client privilege applicable where information gleaned from a third party is the result of confidential communications between attorney and client?

Evidence Code section 954 provides, pertinently, that a person "... has a privilege to refuse to disclose, and to prevent another from disclosing, a confidential communication between client and lawyer...." The attorney-client privilege is applicable where information gleaned from a third party is the result of confidential communications between attorney and client. (People v. Meredith (1981) 29 Cal.3d 682, 693, 175 Cal.Rptr. 612, 631 P.2d 46; People v. Collie, supra, 30 Cal.3d p. 61, fn. 15, 177 Cal.Rptr. 458, 634 P.2d 534.)
