Rain poured over London streets. Detective Vance checked his watch. Midnight arrived with thick fog. The old mansion stood silent. A shattered window caught attention. Blood stained the Persian rug. Lord Harrington lay completely motionless. His silver cane sat nearby. The killer left no footprints. Vance put on leather gloves. He knelt beside the body. Cold eyes stared straight up. A golden pocketwatch was ticking. The time showed twelve fifteen. Mystery hung in the air.
