PI Nigel Strangeways stars in a Golden Age mystery that's "highly literate, intelligent and witty, with twisty puzzles" (Classic Mysteries).

Tampered pianos, tennis balls dipped in molasses, and mysterious forces pulling idle swimmers underwater: the "Mad Hatter" is wreaking havoc at Wonderland summer camp and his pranks are getting dangerous. Enter private detective Nigel Strangeways.

The camp's owners are convinced a rival firm, desperate to put them out of business, is behind the events. But with four hundred guests, an angry hermit, and plenty of disgruntled employees, the Mad Hatter will be hard to uncover—even for a sleuth as brilliant as Strangeways.
