The grand clock struck midnight with a deep, resonant chime. Lord Ashworth lay dead in his study, a silver dagger. The only witness was the storm raging against the windowpanes. His final letter remained unfinished upon the polished mahogany desk. A single drop of blood stained the otherwise pristine carpet. The door was locked from the inside, according to Jenkins. Yet the butler’s account contained one inexplicable inconsistency already. Outside, the wind howled like a betrayed lover in anguish.
