Long time since I read it, but I recall it as one of the best of the Greenes
I just started, but there's from the get-go that understated scene and character-setting mastery that really impressed me in The End of the Affair (the only other Greene novel I read).
Yes, I like End of the Affair too. I've read almost all of his stuff, but the other ones I go back to are Gun for Sale, Confidential Agent and Ministry of Fear and from a later period, The Quiet American.
