A thick cold fog rolled slowly over the quiet village as the old clock tower struck the hour of midnight. Detective Eleanor Gray stepped carefully through the tall iron gates and paused before the darkened entrance of the old estate. A single narrow beam of light escaped from the library window, cutting sharply through the heavy darkness of the night. She pushed open the heavy door and stepped inside as her eyes adjusted to the dim glow of the room. On the Persian rug near the fireplace lay the lifeless body of the wealthy Lord Cavendish, his eyes wide open. A shattered crystal glass rested beside his outstretched hand, and a faint smell of bitter almonds hung in the air.
