The cold rain hammered the manor windows as Detective Mara Venn stepped into the candlelit library and saw the body. A polished silver letter opener protruded from Lord Ashcombe's chest while twelve silent guests stood frozen near the roaring fireplace. Mara knelt beside the corpse and noticed one shattered glass, a missing signet ring, and fresh mud on the rug. "Nobody leaves this room tonight," she said quite calmly, though her gloved hand trembled above the dead man's cold wrist. The fierce storm had sealed every window and door, leaving the killer trapped inside with Mara and eleven terrified witnesses. On the marble mantelpiece, a half finished brandy glass bore faint lipstick marks that matched Lady Ashcombe's crimson smile perfectly. Mara studied the locked French doors and realized the killer had staged the scene before the guests discovered Lord Ashcombe. A single black leather glove lay beneath the desk, its fingers stained with blood and smelling faintly of bitter almonds. When the clock struck midnight, the library lights flickered once and the murderer slipped a key into Mara's coat pocket. Mara felt the cold metal and knew the final clue was placed by someone standing much too close behind her.
