Heist!: The $17 Million Loomis Fargo Theft (2005) by Jeff Diamant. Generic prose but otherwise an entertaining account of greed, stupidity, dumb luck and criminal audacity. A bit like if The Trailer Park Boys relocated to North Carolina.
Nightmare in Berlin (1947) by Hans Fallada. Not as good as Fallada's Everyone Dies Alone (a great underrated novel), but well-written. A grim story of a married German couple going through hell in post-war Germany.
The Professor and the Madman: A Tale of Murder, Insanity, and the Making of the Oxford English Dictionary (1998) by Simon Winchester. Fascinating real life story, especially the parts dealing specifically with the OED, but the writer gets too cute with invented novelistic details: “The horses were sweating lightly,” etc. Just the facts, ma’am!
