The old house stood silent. A single light burned inside. Detective Gray arrived at midnight. He found the library door. Inside, a body lay still. The victim was Lord Ashworth. A knife protruded from his chest. The room held its breath. No forced entry was apparent. The butler waited outside, pale. "I heard nothing," he whispered. Gray examined the cold fireplace. Ash lay scattered on the rug. A single pearl gleamed there. It did not belong here. The mystery had just begun.
