The Untouchable looks good, based on the spy Anthony Blunt apparently. I read his The Book of Evidence and liked it and keep meaning to check out more of his stuff. Troubles by J.G. Farrell is another good Irish novel I read recently (Banville writes the intro).

Now I'm on to The Invisible Man by Wells. Good, fast-paced and with a lot more humour than anything else I've read from him.
