Murder by the Barrel

During the move into the McMillans' new house, Sally is terrified to discover a dead body in one of the barrels delivered by the movers. She calls Mac, but when he and Sgt. Enright arrive, the body is gone. As Sally tries to prove that she didn't imagine it, Mac and Enright investigate the moving company and discover that several people have lost items and have also reported missing persons on the same day.
