Rain beat against the glass. Thunder echoed in the dark. Detective Vance entered the room. Cold air filled his lungs. A shattered glass lay nearby. Crimson blood stained the rug. The body rested beside it. Lord Harrington was dead now. His expensive gold watch stopped. The hands pointed at midnight. Vance slowly knelt beside him. A silver letter opener gleamed. It pierced his velvet vest. No signs of struggle appeared. The killer knew this man. Vance checked the heavy door. The brass lock was engaged. Nobody could leave the house. The murderer was still inside.
