Our Man In Havana by Graham Greene

The book is a satirical espionage novel set in pre-revolutionary Cuba, where a hapless vacuum cleaner salesman is recruited by British intelligence to serve as their operative in Havana. Despite his lack of experience and qualifications, he fabricates intelligence reports to appease his superiors, inadvertently triggering a cascade of increasingly absurd and dangerous events. As the line between fiction and reality blurs, the protagonist finds himself entangled in a web of deception and political intrigue that satirizes the absurdities of the Cold War era and the follies of intelligence agencies. The 1225th greatest book of all time
