A man, giving his name as Mr. Morgan, goes to the police station with a theory about the murder of a girl named Helen Jameson, which the police have assigned to a man who killed two other girls. Because of the same method of the murder by nylon stockings and a painted "A" in lipstick, the police assume the third girl was killed by the same person, even though the murderer denied this, even while confessing to the other two. There was no evidence either, for the third murder of the Jameson girl, but the police will not listen to Mr. Morgan. Mr. Morgan goes to the Lieutenant and even the press, but no one will take him seriously as anything other than a bumbling old man. At last, a kindly priest listens to the frustrated elderly gentleman - however, he cuts him off before he gets to the heart of the matter, which is the fact that the girl lived such a strict, stifled life, she had run away from home and fled to the theater. Dejected and beside himself with frustration, the man goes home to his wife. She tries to shush him as he relays how no one would listen to him...because who would believe that a mother would kill her own daughter. His wife gives an evil grin as she closes a cabinet door on the lipstick and her daughter's clothing, the remnants of the murder she committed.
