The old mansion stood silent beneath a moonless autumn sky. Rain tapped softly against the fogged windows of the library. On the Persian rug, Lord Blackwood lay motionless and cold. His widowed sister, Clara, stood trembling by the crackling fireplace. The butler, Jenkins, discovered the lifeless body at precisely midnight. Detective Eleanor Vance arrived quietly before the local police did. Her sharp gray eyes slowly scanned the room for clues. A shattered brandy glass gleamed beside the victim's outstretched hand. The heavy oak door was locked securely from the inside. Five nervous guests remained in the house that dreadful night. No footprints marred the muddy earth outside the library window. Someone among them had surely silenced Lord Blackwood forever tonight.
