At the same time, the Pentagon is readying an operation to rescue a key group of prisoners in a North Vietnamese prisoner-of-war camp. One man, they find, knows the terrain around the camp better than anyone else they have: a certain former Navy SEAL named John Kelly.

Kelly has his own mission. The Pentagon wants him for theirs. Attempting to juggle the two, Kelly (now code-named Mr. Clark) finds himself confronted by a vast array of enemies, both at home and abroad - men so skillful that the slightest misstep means death. And the fate of dozens of people, including Kelly himself, rests on his making sure that misstep never happens.

Men aren't born dangerous. They grow dangerous. And the most dangerous of all, Kelly learns, are the ones you least expect...
As Clancy takes us through the twists and turns of Without Remorse, he blends the exceptional realism and authenticity that are his hallmarks with intricate plotting, knife-edge suspense and a remarkable cast of characters.
