The ""magic world"" fobbed off on the unsuspecting youngster is an agglomerate of old and new and faintly passe (slang) and tells of Joe, down for his term holiday in Brighton (England) where he finds a stray dog. The dog not only talks, but talks back; actually he is not a dog-- he is a Griffon and he can read and fly. Together they treasure hunt and their rewards are considerable: a flying carpet- and they also win a Superslic washing machine in a department store contest for the nice old lady with whom Joe stays... The illustrations, not seen, by Janina Domanska may help redeem the story; the author did the earlier (1964) Two Gold Dolphins; and this is a galimaufrey of archaic allusions (Atlantis, etc., etc.) and neo-modernisms which requires a most flexible imagination in the young reader.
