Lucy Worsley, Agatha Christie: An Elusive Woman. Fun and easy to read, plus the first set of photo has perhaps the greatest photo I ever have seen, with the caption: “Agatha’s brother Monty liked flirting, ‘talking slang’ and ‘getting into tempers’. He disliked any kind of work. In later life he behaved badly with firearms and became addicted to morphia.”
Alan S. Blinder, A Monetary Fiscal History of the United States, 1961-2021. A very good introduction to these topics from a mainstream point of view.
There is also Stephen M. Stigler, Casanova’s Lottery: The History of a Revolutionary Game of Chance.
And Sean Carroll, The Biggest Ideas in the Universe: Space, Time, and Motion.
Tom Mustill, How to Speak Whale: A Voyage into the Future of Animal Communication. Will the greatest achievement of AI be allowing us to speak with whales?
