The following day, Dr. Archer tells Detective Dart that he is sure the body Frimbo burned was the body he examined the other night. He then says that he believes Frimbo has paranoia. He explains that Frimbo appears to believe that others discriminate against him and want to murder him. As a result, he believes that he has a superior mind and is beyond any ordinary human order. This belief is amplified by his determinist philosophy. Dr. Archer also reveals that Frimbo seems to only let certain people into his life, and he appears to perceive Dr. Archer as someone he can trust. Dr. Archer adds that he will be returning to Frimbo’s house that day. Dr. Archer tells Dart that the tooth bridge belonged to the corpse and proves that Frimbo killed him. Detective Dart then visits dentist Dr. Chisholm Dell, or Chizzy. Chizzy tells him that the bridge is made of deckalite, a new compound that is still only used by two dental mechanics. He gives Dart their names and addresses, and Dart leaves.

At Frimbo’s house, Dr. Archer takes a sample of Frimbo’s blood and notices the red blood cells clumping together again.
