Bernard Samson is a spy for MI-6.
He has been one for most of his adult life. He is intelligent, though not considered exceptionally bright. He is very good at his job, though he is routinely dismissed by peers and seniors. He is a devoted family man, though his wife left them all and he has since had an affair. As can be seen, Samson is a contradiction on many fronts, which makes him understandable and quite believable.
The Samson saga is told in three sets of trilogies.
Game, Set, and Match: this three-book story tells of Samson's chance to rise far higher in the Service only to see that chance destroyed as his wife is revealed as a traitor who has fled to Moscow and Samson is shown to be either duplicitous or stupid. Reeling with the betrayal, he struggles to retain at least some dignity.
Hook, Line, and Sinker: this set of three reveals the agony and tribulations that befall Samson as he begins to learn the truth behind his wife's actions but must still get on with his own life. Torn between wanting the old back as it was and knowing that he must really make the best with what he has left, Samson has even more trouble finding his wife isn't a traitor as he did when everyone thought she was.
Faith, Hope, and Charity: with the fall of the Iron Curtain and the end of that Cold War, the sense of loss of purpose and the wondering as to where to go from there in the new world leaves everyone shellshocked. But there are still questions unanswered and the desire to know the truth clashes with those who would rather forget the old days. But chief among the issues is the question, what does a warrior do when the war is over?
