The fog swallowed Blackthorn Manor. Inside, the clocks struck midnight. At dinner, someone mentioned murder. Nobody laughed except the victim. Lord Ashcombe raised his glass. The candlelight trembled against it. Then every lamp went dark. A single scream pierced everything. The lights returned moments later. Ashcombe lay beneath the table. Blood darkened his ivory waistcoat. His glass remained perfectly full. Detective Vale checked his pulse. Across the room, somebody wept. A bullet had pierced him. Nobody had heard the shot. There was no gun, either. Then Vale noticed the footprints. They began beneath Ashcombe’s chair. They ended at the wall.
