Fog swallowed the midnight lane. A body lay beneath oak. Blood had stained the carpet. Detective Marlowe stepped into silence. Moonlight carved the kitchen knife. Neighbors whispered behind heavy curtains. Footprints led away, then stopped. An old clock remembered everything. He knelt, listening for answers. A perfume ghost hovered above. There were receipts in drawer. Someone had staged the scene. Marlowe's jaw tightened like steel. Night promised more unsaid truths.
