Without Remorse

Two missions, two wars, one man – and time running out
 
In without remorse, it's hero with John Kelly, a man well familiar to clancy's readers by his code name Mr. Clark.
 
John Kelly, former Navy SEAL and Vietnam veteran, is still getting over the accidental death of his wife six months before, when he befriends a young woman with a decidedly checkered past.
When that passed reaches out for her in a particularly horrifying fashion, he vows revenge and, assembling all of his old skills, sets out to track down the men responsible, before it can happen again.
 
At the same time, the Pentagon is retailing an operation to rescue a key group of prisoners in the north Vietnamese prisoner of war camp. One man, they find, knows the terrain around the camp other than anyone else they have a former Navy SEAL named John Kelly. As Clancy takes us through the twist and turns up 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
