Stanford professor Sam Rockman suffers the crushing loss of his wife in a bombing at San Francisco Airport. Casting about to find meaning in the ruins of his life, he accepts an offer to come to Washington , D.C. to work for the Senate Intelligence Committee. What Sam wants out of his stint in D.C. is revenge for the death of his wife. What he gets is danger and betrayal. Secret documents are showing up on his doorstep. Russians are trying to poison him. A renegade CIA asset is strewing nuclear materials up and down Interstate 95. Sam finds allies among a savvy Kentucky senator, a billionaire investment banker, his wife's old rabbi, and the president's national security advisor. Too often, he finds himself thrown together with his counterpart on the other side of the aisle, the whip-smart, six-footer Cecilia Plant. Mourning still for his wife, Sam steels himself against Cecilia's appeal and remains suspicious of her motives.
