The grand library held its breath that Tuesday morning. Sunlight cut through stained glass, painting crimson patterns on silence. A body lay sprawled across the Persian rug, still. It was Lord Alaric Vance, his final expression frozen. A crystal tumbler lay shattered beside his outstretched hand. The scent of old books mingled with something metallic, bitter. Not a single window was broken; the doors were locked. Inspector Thorne arrived, his face already wearing a familiar grimness. He noted the position, the watch stopped precisely at midnight. The first clue was a single, misplaced volume on history.
