Heavy rain washed the blood from the cold cobblestone street. Detective Arthur Vance stared down at the brutally mutilated corpse. The wealthy victim wore a ruined suit of Italian silk. A silver dagger protruded from his twisted and broken spine. Lightning flashed above the towering spires of the cathedral roof. Officer Jenkins held a flickering lantern over the gruesome scene. Nobody heard the desperate screams over the raging thunderstorm tonight. Vance crouched close to inspect the deeply carved neck wounds. Someone had placed a black rose inside the dead mouth. The notorious phantom killer had finally returned to terrify London.
