Discworld novels by Terry Pratchett. First couple of books is a case of the author finding the right style. However after those the books flow better. Sci/Fantasy humour setting. Around 20 books in the series.

“The whole of life is just like watching a film. Only it’s as though you always get in ten minutes after the big picture has started, and no-one will tell you the plot, so you have to work it out all yourself from the clues”

“The reason that the rich were so rich, Vimes reasoned, was because they managed to spend less money.

Take boots, for example. He earned thirty-eight dollars a month plus allowances. A really good pair of leather boots cost fifty dollars. But an affordable pair of boots, which were sort of OK for a season or two and then leaked like hell when the cardboard gave out, cost about ten dollars. Those were the kind of boots Vimes always bought, and wore until the soles were so thin that he could tell where he was in Ankh-Morpork on a foggy night by the feel of the cobbles.

But the thing was that good boots lasted for years and years. A man who could afford fifty dollars had a pair of boots that'd still be keeping his feet dry in ten years' time, while the poor man who could only afford cheap boots would have spent a hundred dollars on boots in the same time and would still have wet feet.

This was the Captain Samuel Vimes 'Boots' theory of socioeconomic unfairness.”

Air America. Is about CIAs covert airforce they created. Mainly creating various companies to support their covert actions.

“Air America – a secret airline run by the CIA – flew missions no one else would touch, from General Claire Cennault’s legendary Flying Tigers in WW II to two brutal decades cruising over the bomb-savaged jungles of Southeast Asia. Their pilots dared all and did all – a high-rolling, fast-playing bunch of has-beens and hellraisers whose motto was ‘Anything, Anywhere, Anytime’. Whether it was delivering food and weapons or spooks and opium, Air America was the one airline where you didn’t need reservations – just a hell of a lot of courage and a willingness to fly to the bitter end.”

Deadly Illusions. In-depth and a heavy read. About KGB spymaster who recruited the Cambridge Spy Ring( large spy scandal in British government from 1930s -50s). Then played a game of wits against Stalin and US/UK governments when he defected to The West.
