Wheatley produces a new type of hero in Robbie Grenn, a charming but mentally challenged young man who, owing to an injury when young, has never been to school, and is regarded by his family as an outsider. Espionage would hardly seem to be his métier, yet to prove himself Robbie takes up the challenge that lands him in peril of his life many times. Interwoven with his adventure is the story of his relationship with the lovely Stephanie, the first girl with whom the shy Robbie has had more than a passing acquaintance. Embodying in his exciting narrative stories from Greek mythology, Wheatley present the gods and heroes as human characters involved in tragedies and comedies as grim or humorously bawdy as any put upon the Restoration stage.
