Rain hammered the old windows. Detective Cole entered the room. A body lay there, still. Blood pooled across the floor. The victim wore expensive clothes. His eyes stared at nothing. Someone had stopped his heart. Cole knelt beside the corpse. A knife rested nearby, gleaming. No witnesses came forward yet. The mansion held many secrets. Cole studied each tiny detail. This case felt deeply personal. He recognized the dead man. They had been close once. Now questions demanded urgent answers. Who wanted this man dead? The night grew colder still. Cole pulled his coat tighter. This would be long work.
