|summary=A lexicon of the world behind the characters, this nicely produced hardback will delight Horrid Henry's and Moody Margaret's hard-core fans, while many a parent will snort in delight at the anarchic spirit of naughtiness that Henry embodies (while sending thanks for not actually having to cope with a Henry of their own). Obviously, no smelly-toady-goody-two-shoes are allowed to put their scrubbed-clean hands on this book.
