Rain hammered the gaslit alley while Lady Ashcombe entered the locked library, pale, shaking, and bleeding profusely from the neck. A shattered mirror, a spilled tea tray, and a torn card reading MURDER waited beneath her trembling hand at once. Detective Hale arrived, noting blood on the carpet, but the corpse was missing and the key remained inside the room.
