The grandfather clock struck midnight when the body was discovered. Eleanor Blackwood lay motionless on the cold marble library floor. A single red rose rested gently beside her pale hand. Detective Marcus Stone arrived at the mansion within the hour. Rain pounded against the tall windows like desperate angry fists. The butler stood trembling near the doorway clutching his keys. No one had heard a scream or any struggle tonight. Yet someone in this house had committed a terrible crime. Stone knelt beside the body and examined her silk dress. There were no visible wounds or any signs of violence. The poison had worked quickly and with devastating cruel efficiency. Five guests remained in the house on this stormy night. Each one had secrets they desperately wanted to keep hidden. The detective stood slowly and surveyed the room with care. Somewhere among these frightened faces lurked a cold blooded killer.
