London match: a bernard sampson novel - len deighton

Bernard Samson suspects there is a traitor within his department of MI6.

A jaded but highly skilled British intelligence agent nearing the end of his career, Samson already got KGB major Eric Stinnes to defect.

But when a British KGB agent makes a sweeping confession with a suspicious undertone, the finger points straight back to London--where Stinnes is locked up, refusing to talk.

The spy whos in the clear doesnt exist.

In the spec-tacular third novel in Len Deightons Game, Set, Match trilogy, will Samson make the winning move?.
