The fog rolled in silently. Detective Sarah Chen parked outside. The Victorian mansion looked ominous. Rain drummed against her windshield. She grabbed her leather notebook. The front door stood open. Blood stained the marble floor. Mrs. Whitmore lay there motionless. Her emerald necklace was missing. The grandfather clock struck midnight. Chen stepped carefully around evidence. Muddy footprints led toward stairs. A wine glass lay shattered. The killer had left quickly. This would be another sleepless night for the weary detective.
