Four of the seven Trustees have been defeated and stripped of their keys; Suzy Blue and Fred Gold Numbers have been captured by the Piper, whose New Nithling brigades control most of the Great Maze.

In the midst of this depressing chaos, Arthur must weigh a suspicious offer from Lady Friday. No doubt about it: The race to find the secret of the Middle House is on!
