Deadly Codes: A Gallagher Novel is the award-winning sequel to Fatal Gamble. Daniel Cormac Gallagher, Jr., a Boston private eye, is hired to investigate the death of Jennifer Clark, tragically killed in a car bombing in her own driveway.
Gallagher has been commissioned by Jeanne Campbell, Jennifer's twin sister, to find a mysterious woman--Jennifer's secret lesbian lover who vanished immediately after the bombing. While the authorities continue to pursue their suspicions that the terrorist act may have been intended for Jennifer's husband, Bill, who holds a top-secret position in the counter-intelligence division of the National Security Agency, Jeanne reveals intricate details to Gallagher that intrigue him enough to take on the case. While Gallagher begins searching for the missing woman, he has no idea that a bounty has been placed on his own head. Two hired gunmen are plotting to kill him. Gallagher's search takes him to Washington D.C. where he discovers that the car bombing is only a backdrop to a complex, treasonous scheme to sell code-breaking formulas to a hostile enemy nation.
As the violent mystery unravels, Gallagher finds himself under deadly attack from two shocking but powerful forces -- one he knows and another he never expects.
