Our Man in Havana is one of what Graham Greene described as 'entertainments' rather than his serious novels, but with the benefit of hindsight it does take on a more serious aspect. Greene was in MI6 in 1941, which this novel satirises, and it predates, and anticipates the Cuban Missile Crisis of 1962. It concerns a somewhat hopeless English vacuum cleaner salesman in Havana, who is approached by a mysterious Englishman who offers him extra money in exchange for a little espionage. He fabricates his reports, but they are taken seriously by MI6, and remarkably, start to come true. It's written as a farce, but it's also exciting, readable and compelling, especially when viewed from the 21st Century.
