the seal of confession

I thought this was probably outdated or overstated, the extent to which the priest was bound to silence, but according to catholiceducation.com "The sacramental seal is inviolable. Quoting Canon 983.1 of the Code of Canon Law, the Catechism states, "...It is a crime for a confessor in any way to betray a penitent by word or in any other manner or for any reason" (No. 2490). A priest, therefore, cannot break the seal to save his own life, to protect his good name, to refute a false accusation, to save the life of another, to aid the course of justice (like reporting a crime), or to avert a public calamity. He cannot be compelled by law to disclose a person's confession or be bound by any oath he takes, e.g. as a witness in a court trial. A priest cannot reveal the contents of a confession either directly, by repeating the substance of what has been said, or indirectly, by some sign, suggestion, or action. A Decree from the Holy Office (Nov. 18, 1682) mandated that confessors are forbidden, even where there would be no revelation direct or indirect, to make any use of the knowledge obtained in the confession that would "displease" the penitent or reveal his identity.

(Just as an aside, a great movie which deals with this very topic is Alfred Hitchcock's "I Confess," which deals with a priest who hears a murder confession and then is framed for the murder. As a priest, I was in agony during much of the movie.)
