Homicide: Life on the Street (1993) : 7x4

A woman brings to the homicide unit her mystery-writer husband's videotaped declaration that his literary agent is responsible for his murder. Ballard and Gharty catch the case -- only there is no body or crime scene. Meanwhile, Munch and Bayliss investigate the death of an elderly woman that occurred during a break-in -- was it a homicide? Munch would rather leave for his weekend rendezvous with Billie Lou. Ballard and Gharty's investigation becomes a red-ball as they find evidence in the writer's office that a crime was committed. A break leads to the arrest of the literary agent and his accomplice, although Danvers can't guarantee a conviction. Falsone asks Ballard if she would like to go out Saturday night; just then the jury comes back. And a sharp-eyed juror insures that justice is done.
