The rain drummed on the windowpane. A body lay on the floor. The clock struck midnight's lonely chime. Detective Gray examined the scene. A single bullet casing rested nearby. No signs of forced entry existed. The victim held a broken pocket watch. A faint scent of perfume lingered. Footprints led toward the garden door. Someone had known their way here.
