The rain fell hard on the old mansion's stone roof. Inside, the guests huddled near the warmth of the fire. A scream cut through the howling wind outside the house. Everyone froze, their drinks halfway to their own trembling lips. In the library, Lord Ashford lay dead upon the carpet. A sharp dagger protruded from his silk waistcoat quite grotesquely. Blood stained the pages of an open rare first edition. The butler entered, his face pale as the fresh snow. "Nobody leaves this room," the tall inspector said quite firmly. Outside, the fierce storm ensured no one could escape tonight.
