"$100,000 worth of radium vanishes...three men are mysteriously killed...a corpse comes back from the dead...and it's only the beginning folks, only the beginning!"
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.
