Rain tapped against the window. Shadows danced across the floor. A scream shattered the night's calm. Detective Morris lit his cigarette. Footsteps echoed in the hallway. The victim lay cold, still. Blood pooled beneath the shattered vase. No one moved; fear settled. Secrets whispered from every corner. The clock ticked with menace. Detective sighed, eyes scanning room. Someone in here was lying. The truth hid in darkness. Detective knew this was personal. A killer walked among them.
