I loved Slough Horses by Michael Herron. I am a huge fan of spy novels. (But I really don’t like true crime… go figure.) This was a take on the classic “band of misfits” does good story. The book took some time to get started, but once it did, it roared to life.
Just finished Billy Boyle by James R. Benn. The writing was a bit rough at the start, but by the end I was converted. A great book if you just need some time away and are looking for a quick espionage read.
