Rain tapped the library windows. The clock struck midnight softly. Old Lord Ashby slumped down. A silver knife gleamed nearby. Detective Mara entered the room. She saw the crimson stain. Something smelled like bitter almonds. Every window was locked tight. The door stood slightly open. Someone had left this party. Mara touched his cold hand. No pulse answered her fingers. Then the lights went out. A scream shattered the silence. Footsteps hurried down the hall. Mara drew her small pistol. The murderer was still nearby.
