The relentless midnight storm battered the ancient stained glass windows while Lord Arthur Pendleton bled out on the marble floor. Detective Harrison Vance knelt beside the lifeless body, noting the strange angle of the cursed silver dagger in his chest. A thick velvet curtain twitched slightly in the drafty old room, revealing a secret door behind the large oak bookshelf. Five wary guests remained trapped inside the sprawling estate, each possessing a clear motive to silence the wealthy aristocrat forever. Beside the cooling corpse rested a crystal glass of port, laced with a rare poison extracted from deadly nightshade berries. Shadows danced across the grand walls as Vance realized the ruthless killer was still hiding within the dark manor house.
