Luff Imbry returns from the weird planet Fulda, to which he was shanghaied by a mysterious enemy, only to find that an impostor has stolen from his private club’s strongroom the collection of magical paraphernalia he acquired from a would-be thaumaturge who tried to kill him.

The theft should be impossible, but Imbry has to deal with reality. He sets off on a quest to solve the mystery and recover his goods, bringing him into conflict with shadowy forces that are preparing for the great change, when the universe once again gives up on rationalism and embraces an age of magic.

The odds are against him, but Imbry is a great improvisor.
