The silver tray fell onto the dark red velvet carpet. Lord Harrington lay very still beside the cold stone fireplace. A single drop of crimson blood stained his silk cravat. Outside the library, the heavy rain lashed against the glass. No one heard the muffled scream behind the locked door. The killer fled through the dark garden in total silence. Only the ticking clock witnessed the final breath he took. Detective Miller pushed the grand oak doors open with force. He noticed the smell of bitter almonds in the air. This was not an accident but a very clever trap.
