Frazer's pursuit involves cars and boats and colourful characters, but he manages to survive while others around him perish. A Russian ship has just been wrecked off the Yorkshire coast and a man from the boat dies in a local hostelry.
Frazer eventually becomes enlightened as the various clues are pieced together.
