Plot summary
In the show’s 100th episode, after a rock star ( Steve Valentine ) serves a term in jail for manslaughter, Shawn and Juliet are invited to a party celebrating his release. When Juliet is tied up at the station with work, Shawn takes Gus instead. During the party, held at a large mansion, one of the guests is murdered. Lassiter and Juliet join the guests in trying to figure out what happened. When more dead bodies pile up, the guests start pointing fingers at each other. It is up to Shawn to unmask the real killer.
The ending of this episode was chosen based on live online fan votes. As a result, the east coast and west coast airings ended with different killers. The episode parodies the movie Clue, featuring a mansion reminiscent of the one from the film, as well as three cast members of that movie as guest stars ( Christopher Lloyd, Lesley Ann Warren, and Martin Mull ). Garrett Morris also guest stars, as Clizby the Butler.
