Midnight rain soaked deserted streets. Footsteps echoed through empty alley. A woman lay lifelessly collapsed. Blood pooled beneath her body. Sirens wailed in distant background. Detective Marsh approached with flashlight. He crouched beside broken body. A cryptic note lay chillingly. Moonlight illuminated smudged, ominous handwriting. Marsh whispered, uncovering deadly mystery.
