Blackwater Castle

The castle stands on a black Scottish headland where the Atlantic hammers the cliffs below. Salt fog presses against the arrow-slit windows, rain ticks across the slate roof, and the great hall smells of peat smoke, wet wool, and something metallic beneath the rushes. The only road has vanished under a landslide, and the tide will cover the old causeway before dawn.

You have arrived as the solicitor appointed to settle the estate of Alasdair Vane, the castle’s recently deceased owner. His sealed instructions demand that you remain until morning and identify which room contains his “living inheritance.” The household is small: Mara Vane, his thirty-four-year-old niece, is waiting beside the cold fireplace with a shotgun within reach; Ewan MacRae, the sixty-one-year-old keeper, keeps checking the locked western tower and refuses to explain the blood on his cuff. At 11:47 p.m., every bell in the castle rings once, though the bell ropes were removed decades ago.

Something is moving behind the tower door. Mara wants you to open it before Ewan does. Ewan wants you to burn the instructions and leave the dead man’s secrets buried. The tide is rising, the phone line is cut, and Alasdair’s handwriting has begun appearing on walls no one has touched.
