The Penitent - David Mamet - Bog

A renowned psychologist, Charles, is asked to testify on behalf of one of his former patients who has committed a shooting. At first he is hesitant, and as his lawyer and his wife begin to tell him how he should handle the situation, Charles clings more fervently to his morals and his ethics. However, the tighter he clings, the more his reputation and career hang in the balance, especially as more truths are revealed about his relationship to his patient.
