device, but dies under suspicious circumstances before he can demonstrate the device to his friends. Another scientist who has seen the device demonstrated suspects that Villiers has been murdered by one of his classmates, and he questions them. In the course of his investigation, a photographic record of a research paper by Villiers describing his theory is discovered on a windowsill of the room, but is found to have been ruined through exposure to sunlight. When none of the suspects admits any guilt, Wendell Urth, an eccentric scientist who has had success in investigating crimes, is brought in. He identifies the guilty astronomer as the one who has been on Mercury. The key lies in the idea (at the time of writing believed to be true) that Mercury has one face always pointing away from the Sun. The guilty party had hidden the film in what he thought was a safe place because he subconsciously expected the night to last forever. Since the story was written, it has been discovered that Mercury is not

's dictum " A foolish consistency is the hobgoblin of little minds." In-universe, the inconsistency can possibly be explained by Romero's invention actually being a way to teleport living beings, since in "The Singing Bell" the teleportation is only used for transporting inert cargo (with humans taking regular transport), while Romero explicitly states he managed to teleport a mouse. Teleportation and FTL transportation are shown to be a more difficult task with living beings than inert cargo in numerous works of science fiction, including Asimov's own short story "
