At midnight, Mrs. Vale discovered blood beneath the library door. The grandfather clock struck thirteen as she turned the key. Inside, her husband sat upright, smiling at the empty fireplace. A silver letter opener protruded from his immaculate evening waistcoat. On the mantel, someone had arranged three fresh white roses. Mrs. Vale counted them twice, then summoned the household downstairs. By morning, every rose had vanished, along with the butler.
