and Cheryl look around the building when they find blood on the antique weapons and discover the chauffeur's body. Clay points out that the other sword from the display is missing, and Austin finally calls the police, stating to the police commissioner that the killer is still inside the clinic. The police and medical attendants remove the bodies of Anne, Ruth, Mara, and the other nurse from the area, but they are angry that Dr. Austin moved some weapons and tried to keep the killings a secret, thus making him an accessory after-the-fact. The police inspector suggests using Cheryl as bait, and Dr. Clay tries to get her to rethink the idea after she agrees to it. While all the other clinic patients are moved into a single room for their own protection, Cheryl awaits in her room. The killer approaches with a rope to strangle where he removes his hood... finally revealing himself to be her husband, Hume. The police detectives show up before he can finish strangling Cheryl and chase Hume around the building. Clay and Austin theorize that Cheryl's husband wanted to kill his wife for some time and he created the idea of a maniac spree killer so that no one would suspect him of Cheryl's murder. Hume knocks out two of the cops chasing him and upon running into a room to hide, discovers all of the clinic's female nurses in it. Hume goes on a brutal killing spree, killing every woman in the room before the police run in and finally shoot Hume dead.
