At midnight, Inspector Vale found the conservatory locked, its glass walls fogged from within despite the cold November rain outside. Inside, beneath the dead orchids, a man lay face down, one hand curled around a fresh white chess knight. The victim was Judge Harrow, whose dinner guests had spent the evening insisting he had no enemies among them whatsoever. Vale counted six guests in the hallway, then noticed seven damp umbrellas dripping onto the marble floor behind their feet. Mrs Harrow said her husband never played chess, but someone upstairs had just moved a piece across a wooden board.
