Detective Mara Voss arrived at old Blackwood Manor as the morning fog curled around the iron gates like ghostly fingers. Inside the grand foyer, a young maid stood trembling beside the body of Lord Ashworth, crumpled beneath the marble staircase. His silver pocket watch had stopped at precisely midnight, and a single crimson rose rested gently upon his silent chest. Voss knelt beside the fallen man and noticed something strange about the victim's hands, which were oddly clean and smooth. There were no marks of struggle anywhere, yet every servant in the house claimed they had heard nothing at all. The detective studied the locked windows, the bolted doors, and the storm that had sealed the manor away from everyone. Somewhere above, a grandfather clock began chiming the hour, though its hands pointed stubbornly toward a time long since past. Voss rose slowly, pulled out her notebook, and wrote one chilling sentence that would haunt her for many years afterward. The killer had never left Blackwood Manor, she realized, and one of the frightened faces watching her belonged to him.
