The Model Rules of Professional Conduct (with each state adopting their own, perhaps different rules) allow a lawyer to disclose confidential client information to prevent reasonably certain death or substantial bodily harm. MRPC 1.6(b)(1).
So the lawyer may have kept his confidence, but may have had the option to disclose.
Unfortunately, not the steel trap that Bill was looking for.

A catholic priest may not reveal anything he learned during the confession, no exceptions. That's the only "profession" I know with such a strong promise of confidentiality.
"Can. 983 §1. The sacramental seal is inviolable; therefore it is absolutely forbidden for a confessor to betray in any way a penitent in words or in any manner and for any reason."
