In the final episode of Murder, She Wrote's third season, Jessica (Angela Lansbury) shows up at a studio to record one of her "Mystery Books for the Blind." Halfway through her recording session, the electricity fails and the studio is plunged into a blackout. When the lights come up again, it is revealed that the studio's co-owner has been murdered. Naturally, the "wrong person" is accused of the crime, obliging Jessica to set things right by exposing the real culprit--and this being a recording studio, rest assured that the most important clue will be aural rather than visual.
