Rain hammered the cobblestones outside Blackwood Manor as Detective Mara Quinn arrived precisely at midnight expecting another false alarm call. The butler opened the heavy oak door, his trembling hands clutching a silver tray bearing untouched brandy for the deceased. In the library, Lord Blackwood lay sprawled across his desk, a jeweled dagger protruding from his chest still warm bleeding. Mara noticed the window was locked from inside, the fireplace roaring despite summer heat, and no footprints visible tonight anywhere. Beside the body, a single white pawn chess piece rested cleanly, contradicting the violent chaos surrounding everything else entirely tonight. The butler whispered that nobody had entered or left the manor since the storm began at eight o'clock that evening. Mara smiled grimly, realizing the killer was still inside, watching her every careful move silently from somewhere within these walls.
