Came across this because the book is now a series on Apple TV starring Gary Oldman (one of my fave actors). Watched the series first then read the book, and enjoyed both immensely. Herron has been christened the new Le Carré, but he's quite a different writer - funny and more accessible, if less profound. The characterisation is great, the plot twisty and satisfyingly complex, the dialogue fantastic. Good modern spy thriller with satiral edge.
