My rating: 4 of 5 stars
Since a long time ago that I wanted to read this book and this opportunity came through BookCrossing.
The story is a parody of the traditional books of spying: when a vacuum-cleaner salesman could become a british agent of MI6 in Cuba?
Another fact that must be taken into account is that this book was written in 1958 for the reader not to lose the historical context of that time.
Alec Guinness and Maureen O’Hara acted in the movie version of this book (1959).
