Dark of Night: A Novel (Troubleshooters)

Only a handful of people in the world know that James Nash is alive.
For years, Nash performed ultra-covert "Black Ops” missions for a shadowy government agency. But when he walked away from their dirty work, his ruthless bosses weren't about to let him go. After their attempt to assassinate him nearly succeeds, his former partner Lawrence Decker, with the FBI's help, fakes Nash's death to protect him.

With Nash secreted away in a safe house, Decker will risk everything-including his heart-as he races to solve the mystery of who wanted Nash dead. Passions will flare as everyone close to the deception finds themselves fighting for survival.
