This is a list of episodes of Psychoville, which ran for two series consisting of 14 episodes, broadcast from 2009 to 2011.
David and Maureen kill another member of the murder mystery evening and hide the body in a wooden chest. As they sort out the mess they have caused, it is revealed that David had killed his father by giving him an overdose of sleeping pills, thinking he was helping him because he looked tired. A policeman, Jason Griffin, then visits the scene of the crime and David pretends to be the murder victim while he and Maureen try to bluff their way out of the situation. It is later revealed that Griffin is actually an actor auditioning for a role in the murder mystery evenings, but before Maureen learns this she tells him that it was in fact her who killed David's father by poisoning him slowly over time and that David's overdose was the final blow. As Griffin leaves, he tells David about what Maureen said about her committing his father's murder. As David confronts her, Griffin returns to get his coat and discovers the body. As a result, David murders Griffin as well.
