The part about being prophetic about the Cuban Missile Crisis was interesting, and I think I'll add The Quiet American to my reading list:
[Greene's] previous full-length novel, The Quiet American (1955), anticipated tragic US military entanglement in Vietnam a decade later. Meanwhile, his Havana-based story would prove remarkably prophetic about another key Cold War episode. Using an Atomic Pile vacuum cleaner as a model, the charlatan Secret Service agent fools his bungling bosses in London with sketches of ‘big military installations under construction’ in the mountains of eastern Cuba, including a ‘large concrete platform’ and ‘strange machinery in transport’.
For a thoroughly enjoyable read I'd also recommend The Comedians.
They would have known the gangsters that Brighton rock uses as the base for some of the characters. One of my cousins who is an actor has actually appeared in a theatre version of Brighton Rock.
BTW this was when off course book making was illegal in the UK
