Choreographer Bob Connolly and prolific screenwriter Crane Wilbur teamed up on the direction of Warner Bros.' The Patient in Room 18. Patric Knowles delivers a delightfully comic performance as Lance, an outwardly normal young man obsessed with detective stories. When his obsession threatens to lapse over into lunacy, Lance is sent to the hospital for a nice long rest. It isn't long before he gets mixed up in a genuine murder mystery, using his second-hand knowhow to solve the case. Up-and-coming Ann Sheridan is quite amusing as Lance's nurse and confidante, while the murderer is played by a fellow who is usually cast as the murder victim.
