Rain lashed the dark glass. Cold wind rattled the door. Inside, the dead man lay. Blood stained the Persian rug. A silver knife gleamed nearby. Detective Vance stepped right in. He examined the pale face. No signs of struggle remained. Someone had locked the room. The window was nailed shut. Only one key existed now. Vance sighed with quiet dread. This was no simple suicide.
