I came across this today:
"...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 in peril of his life many times."
Feel free to insert your own Cretan joke.
