Maddie (Cybill Shepherd) and David (Bruce Willis) are hired by a collection agency to go after a deadbeat debtor named Roy Hirsch. Not long afterward, the detectives come across Hirsch's dead body--which promptly disappears. What does the mystery Man With the Mole have to do with all this? The final episode of Moonlighting's first season, "The Murder's in the Mail" features the series' first "aside" to the audience, wherein David sly breaks down the forth wall and directly addresses the viewer; it is also the LAST time that the series would ever feature a climactic pie fight!
