The Second Saladin — Stephen Hunter

Once Paul Chardy had been among the Agency's best and brightest. Now he was a Cold War burnout, sick of the dirty tricks and dirtier lies.

But the Agency needed Paul Chardy one more time -- and the Agency knew how to make sure he couldn't say no.

Now Chardy has to protect at all costs a man he despises. He has to catch or kill a man he loves. And he has to obey without question a man he could not respect -- and can never trust.
