The rain hammered the mansion's slate roof at midnight. A single candle flickered in the library's oak-paneled study. Lord Ashworth lay sprawled across his mahogany desk, dead. A silver letter opener pierced his embroidered waistcoat precisely. His blood pooled around a half-written letter to his heir. The door creaked open, revealing a shadowed figure standing. Detective Graves stepped in, rain dripping from his coat. He noted the broken vase and the overturned inkwell. "This room holds thirteen suspects," he murmured to himself. "Each one has a motive, and none have alibis."
