Rain fell in heavy sheets. The detective stood at door. A body lay on floor. The room was dimly lit. Something felt off about it. Blood pooled beneath the victim. A single gunshot echoed earlier. No one heard a thing. Neighbors claimed they were sleeping. The detective frowned in thought. This wasn't a random killing. A clue sat on mantelpiece. A photograph, torn in half. The victim's expression was frozen. Fear lingered in the eyes. He picked up the photo. Why would someone do this? The clock ticked past midnight. Silence filled the entire house. Then a floorboard creaked upstairs. His hand moved very slowly. Toward the holstered service weapon. Someone else was still here.
