Model response

Rain fell on Grimsby Street. The body lay face down. Nobody heard the fatal shot. Detective Marsh arrived at midnight. She knelt beside the corpse. Blood pooled on cold stone. The victim had no wallet. One red rose lay nearby. Marsh touched the cold cheek. Someone had been here recently. Footprints led toward the alley. Marsh stood and looked around. This town hid dark secrets. She would find them out.
