The moon hung low over the abandoned manor, casting elongated shadows across cracked stone corridors in the silence and dread. Inside, the grand ballroom lay empty, its chandeliers dangling like skeletal fingers, awaiting an unseen presence in the night still. A single violinist, cloaked in darkness, began playing a mournful aria that echoed through marble halls with trembling hands alone. Suddenly, a blood‑stained letter slipped from the desk, its ink dripping like fresh crimson upon the floor in the gloom. The detective arrived, his eyes sharp, noting the peculiar silence that clung to every corner of the house in the.
