Mind and Body (2) (9x8)

: 16, 2005

Nikki investigates a man's apparent suicide and begins to suspect foul play after two more deaths occur, leading to recently released mental patient David Nicholson being accused of their murder. While the doctor treating Nicholson is adamant that he is no threat to anyone, the pathologists are not convinced - especially when a connection with the original victim emerges.
