Rain pelted the dark window. Thunder shook the old mansion. Lord Blackwood lay completely still. Crimson blood stained the carpet. A shattered glass rested nearby. Bitter poison scented the air. Someone had locked every door. Footsteps echoed down the hall. Detective Vance entered the study. He examined the cold corpse. Nobody could escape the estate. The killer was still inside.
