About the book

Four of the seven Trustees have been defeated and their Keys taken, but for Arthur, the week is still getting worse. Suzy Turquoise Blue and Fred Initial Numbers Gold have been captured by the Piper, and his New Nithling army still controls most of the Great Maze. Superior Saturday is causing trouble wherever she can, including turning off all the elevators in the House and blocking the Front Door. Arthur can't even find out what is happening back home. All he knows is that Leaf isn't on earth any more. She's missing - and so is her family along with Arthur's mother and hundreds of other people who were transferred from regular hospitals to a private institution run by a 'Doctor Friday'. From there they have been taken somewhere else in the Secondary Realms, for Lady Friday's own horrible purposes. Amidst all this trouble, Arthur must weigh up an offer from Lady Friday that is either a cunning trap for the Rightful Heir or a golden opportunity he must seize - before Superior Saturday or the Piper beats him to it. The race is on, to find the secret of the Middle House!
