Lightning split the night sky as thunder rattled the manor. A solitary lamplight flickered within the damp hallway, revealing nothing. Detective Harper approached cautiously, footsteps echoing through the empty corridor. Sudden scream pierced the silence, freezing blood in every heart. Harper discovered Lady Ashcroft’s body sprawled across cold marble floor. A single dagger protruded grotesquely from her pale, silent chest. Blood stained the elegant gown she had worn moments earlier. A storm raged outside, hiding footsteps beyond the stone walls. Harper’s mind raced through suspects as candles guttered, shadows dancing. Somebody in this house knew secrets darker than any storm.
