“ The lamp was turned half down, but Smith could see the details of the room plainly enough. It was all much as he had seen it before—the frieze, the animal-headed gods, the hanging crocodile, and the table littered over with papers and dried leaves. The mummy case stood upright against the wall, but the mummy itself was missing. There was no sign of any second occupant of the room, and he felt as he withdrew that he had probably done Bellingham an injustice. Had he a guilty secret to preserve, he would hardly leave his door open so that all the world might enter. ”
