The old manor sat silent beneath a bruised November sky, its windows dark and unwelcoming as the first guests arrived. Detective Inspector Clara Vane stepped from her car and studied the sprawling estate with narrowed eyes before approaching the door. A constable met her on the gravel drive, his face pale beneath the brim of his hat and uniform collar. "You'll want to see this, ma'am," he said quietly, turning toward the dimly lit conservatory at the back of the house. Inside, the air smelled of damp earth and spilled wine, and a single lamp flickered near the body on the floor. A woman in a crimson evening gown lay crumpled beside the overturned table, her eyes fixed open and utterly vacant. Clara knelt carefully, noting the single stab wound beneath the ribs and the strange absence of blood on her dress. The constable whispered, "The door was locked from the inside, Inspector, and every window is sealed with fresh white paint." Clara looked at the locked door, then at the dead woman, and felt the first cold prickle of suspicion rising. "Then someone in this house is lying," she said, "because no one vanishes from a sealed room without leaving traces."
