recognizes the dead man, but conceals this from his superior. Taking the glove, he goes to see Alice at her father's tobacco shop, but she is too distraught to speak. As they speak privately in the shop's telephone booth, Tracy (Donald Calthrop), arrives. He had seen Alice go up to Crewe's flat, and he has the other glove. When he sees Frank with the other one, he attempts to blackmail them. His first demands are petty ones, and they accede. Frank learns by phone that Tracy is wanted for questioning: he was seen near the scene and has a criminal record. Frank sends for policemen and tells Tracy he will pay for the murder. Alice is apprehensive, but still does not speak up. The tension mounts. When the police arrive, Tracy's nerve finally breaks and he flees. The chase leads to the British Museum, where he clambers onto the domed roof of the Reading Room and slips, crashing through a skylight and falling to his death inside. The police assume he was the murderer. Unaware of this, Alice feels compelled to give herself up and goes to see the Chief Inspector at New Scotland Yard. Before she can confess to him, the inspector receives a telephone call and asks Frank to deal with Alice. She finally tells Frank the truth—that it was self-defense against an attack she cannot bear to speak of—and they leave together. As they do, a policeman walks past, carrying the damaged painting of the laughing clown and the cartoon canvas where Alice painted over her name.
