Original as ever, Mr. Wheatley has produced a new type of hero in Robbie Grenn, a charming but mentally retarded young man who, owing to an injury when young, has never been to school, and is regarded by his family as almost a moron. Espionage would hardly seem to be his metier, yet, to prove that he is as good as other men, Robbie takes up the challenge that lands him many times in peril of his life. Interwoven with his adventures is the story of his relationship with the lovely Stephanie, the first girl with whom the chronically shy young man has ever had more than a passing acquaintance. As this is a Wheatley book, we need hardly add that the suspense is acute and the denouement remarkable. And, more unusual, Mr. Wheatley, with his flair for blending the exciting and the informative, has embodied in his narrative some stories from Greek mythology told in strict accordance with the chronicles, yet in an off-beat manner which presents the gods and heroes as human characters involved in tragedies and comedies as grim or humorously bawdy as any put upon the Restoration stage. These are revealingly counterpointed with the story of Robbie. Mayhem in Greece is another certain best-seller which will enthrall Dennis Wheatley's present readership and extend it, for he is still the 'discovery' of new readers all over the world
