CASTLE - "He's Dead, She's Dead" - When a famous psychic is murdered, Beckett and Castle search for her killer while also carrying on a spirited debate on the existence of extrasensory abilities. Evidence mounts on both sides, especially when a letter arrives from the victim, penned the day she was killed and predicting her own death -- or was it written by a clever killer, hoping to throw off the investigation? -- on "Castle," MONDAY, SEPTEMBER 27 (10:01-11:00 p.m., ET), on the ABC Television Network.
