Cold autumn rain battered the tall glass windows of the old mansion while Lord Blackwood lay dead on the floor. Detective Arthur Vance knelt beside the wealthy aristocrat and carefully examined the silver dagger protruding directly from his silent chest. Every single door inside this massive library had been bolted tightly from within before the fatal strike took his life. Crimson blood stained the expensive Persian rug beneath him, pooling slowly near a shattered crystal glass smelling faintly of almonds. Downstairs in the bright parlor, six nervous guests waited anxiously, each hiding dark secrets and strong motives for cold murder. Vance stood up slowly, realizing the clever killer was definitely still trapped somewhere inside the house with the remaining survivors.
