Yes, my mistake. They are:
the second trilogy is:
Deighton also wrote the Harry Palmer books, which were made into
films in the 1960s (I think) starring Michael Caine. He is also the author
of "SS-GB" an espionage book set in England after the Germans conquered
the country in World War II. He also has a stand alone book which I liked
called "XPD" which is an intelligence shorthand for Expedient Demise.
