Dark of night : a novel
(Book)

Badly shaken after the loss of one of their own, the men and women of Troubleshooters Inc. go up against their most deadly opponents yet--the clandestine organization called The Agency. But when their leader, former Navy SEAL Lawrence Decker, barely escapes with his life, it soon becomes clear that the hunters have become the hunted --and the Troubleshooters are no longer just solving a crime--they're fighting for survival.
