Cold autumn rain hammered the dark city cobblestones as Detective Vance approached the old manor where the body was found. A young uniformed officer lifted the yellow tape, allowing Vance to step inside the grand foyer of the large house. Crimson blood stained the white marble floor beside a crumpled figure wearing an expensive suit and a broken gold watch. Vance knelt carefully near the dead victim, noting that no obvious murder weapon was visible anywhere in the spacious room. He reached into his coat pocket and pulled out a small penlight to inspect the strange marks on the neck. A sudden noise behind him caused the detective to spin around with his hand resting on his loaded service revolver.
