Cracker

When an amnesia victim, covered in blood, is found near the scene of a brutal murder aboard a moving train, the police are convinced they have their killer and bring Fitz in to get a confession. Fitz, however, is less convinced of the suspect's guilt, and takes it upon himself to help the man, the 'John Doe,' recover his memory while he searches for the real killer. Meanwhile, at Judith's insistence, Fitz attends a Gambler's Anonymous meeting, which culminates in Fitz leading the members in a betting frenzy.
