An avant-garde artist (Ann Prentiss) is sure that someone is trying to kill her and that her dead uncle's body isn't in its casket. Against Mac's advice, Pete takes on the assignment of helping Paula Wirehouse (guest star Ann Prentiss) try to establish whether her despised Uncle Barney is really dead and buried. After discovering Barney's casket empty, Pete and Paula beat a grave-robbing charge, only to witness several attempts on the lives of two people near and dear to them — themselves.
