and the others run to find her. In the confusion, Judge Cannon is found dead in his bedroom, shot in the head. Because Vera refuses to confess to her guilt, as the other four have, Dr. Armstrong becomes suspicions of Vera and has her locked in her room. Hugh comes to Vera's room during the night and gives her his gun. Vera reveals that she never escaped justice for a murder. Her sister committed the murder, but Vera took the blame, to protect her. Her sister killed herself afterwards. Hugh reveals that he is in fact Charles Morley. The real Hugh Lombard was his best friend, and also committed suicide after the crime of which he was accused. Charles found Hugh's invitation among his belongings while clearing them after his death, and likewise took his friend's place, hoping to learn more about what caused Hugh to take his life. The next morning, Dr. Armstrong is nowhere to be found. A search of the ruins leads to Blore being pushed off a ledge to his death. Vera and Charles assume Dr. Armstrong is the killer, but are then shocked to find Dr. Armstrong's corpse in the ruins. He has been dead for hours. They realise they are the only two remaining. Vera shoots at Charles. Vera returns to the hotel, where she finds all the furniture covered in sheets again, except for a chair with a noose above. She finds Judge Cannon very much alive.

Judge Cannon tries to convince Vera to hang herself, to avoid spending the rest of her life in jail, since the authorities will assume she is the obvious murderer, as the only remaining guest alive.
