Heavy rain lashed violently against the dark and silent windowpane. Inside, Lord Harrington sat motionless within his crimson velvet armchair. A thin stream of fresh blood trickled down his neck. The grandfather clock struck midnight with twelve deep hollow chimes. Beside the cold fireplace, an antique silver dagger lay abandoned. Footsteps hurried down the carpeted hallway outside the locked study. A trembling hand rattled the polished brass doorknob in vain. Nobody answered because the wealthy master was already quite dead.
