A typical, fast-paced Grade-B murder mystery, Mystery of the White Room was based on the then revolutionary medical breakthrough of corneal transplantation. After being rebuked by hospital administrator Dr. Morton (Addison Richards) for failing to follow procedure, Dr. Clayton (Bruce Cabot) and Dr. Thornton (Frank Reicher) become prime suspects when Morton is murdered during a brief blackout in the operating room. Suspicion quickly centers on Dr. Thornton, who fails an ad hoc lie detector test, and the case seems solved when the good doctor is found dead, an apparent suicide. But neither Dr. Clayton nor the investigating police officer, Sgt. Spencer (Thomas Jackson), are convinced and the former makes the daring suggestion of transplanting Dr. Morton's corneas onto the eyes of the only witness, Tony (Frank Puglia), the deaf-and-dumb janitor who has been blinded with acid by the killer. The operation proves successful and the janitor is able to reveal the surprising identity of his attacker. Mystery of the White Room was the second-to-last of Universal's "Crime Club" thrillers.
