Midnight rain tapped the windows. Candlelight carved shadows across carpet. He found her on floor. Blood pooled like stale wine. A photograph lay, edges damp. The portrait smiled despite everything. Police tape fluttered like ribbon. Neighbors whispered behind drawn curtains. Detective Marlowe crouched, studying scene. He smelled perfume and whiskey. There was a single footprint. It led toward the harbor. A clock stopped at midnight. Marlowe lit another cigarette, silently. He did not yet speak. Someone watched from the stairway. Footsteps retreated into shadowed hallway. The city held its breath. Secrets rustled beneath the wallpaper. A name echoed in mind. He tucked the photograph away. Questions piled like unopened mail. Night promised more dark revelations.
