The silver moon hung low above the jagged cliffs while the cold tide pulled secrets deep into the black ocean. Arthur clutched his velvet coat tightly against the biting wind that howled like a ghost through the twisted oak trees. He stared at the lifeless body resting upon the damp sand where the golden watch ticked away its final hour. A single red rose lay pinned to the victim's chest, signaling that the deadly game had finally begun for him.
