Castle (2009) Season 6 Episode 16
When a guilt-ridden young woman confesses to the murder of a struggling actor — knowing details only the killer could know — Beckett and Castle seem to have an open-and-shut case, until they uncover proof that their suspect couldn’t possibly be the killer. When a second person confesses, equally convinced they committed the murder, the team realizes the case is far more mysterious than they thought.
