I really enjoy the Quiller books by Adam Hall, the David Audley novels by Anthony Price especially "Other Paths To Glory" and the Blackford Oakes series by William F. Buckley.

Its William F. Buckley, Jr. :D And the Blackford Oakes books are fun.

I also like Eric Van Lustbader. He has about 14 books, some are part of a couple of series, and some are standalones. His books are thrillers, and sometimes they have political connections, but often they are about the main character, and business. They are all involved with Japan (modern day :70s to 80s, and past: WWII), and often have Ninjas and things.

Already mentioned this somewhere else, but I'd like to stick Nelson Demille on this list
Lee Child I'm staying away from however after Without Fail

Yes Nelson Demille is a great author, his John Corey creation is great and the role model of everyone I work with. He goes out of his juristiction, ignores his superiors and is sarcastic to most people he meets but he gets the jobs done and we, the reader, have the great honour of being along for the ride.

Lee Child is also great in my eyes. Jack Reacher is everything an ex Military Cop should be.

if you like older stories - and sailing - then "The Riddle of the Sands" by Erskine Childers is an absolute classic, and one of my favourite novels of all time. It was written before WW1 and concerns the accidental discovery by a couple of British sailors of a German plot to invade the UK.

It was even made into quite a good film (for once) in the 1970s IIRC.

Ian Fleming's Bond books, and Peter O'Donnell's Modesty Blaise.
