The Bourbon Diamond is the most valuable diamond in Great Redmond City, and the man who stole it doesn't have long to live. After escaping a shootout with police, jewel thief Dan Snell drops dead in the middle of the street - a stab wound in his back, but the knife, the killer, and the diamond are nowhere to be found. Kleptomaniac murder investigator Felix Green and his uptight partner Sam Alders are on the case in Vanishing Act.
