When Adam Park's former mentor recruits him to locate a vulnerable loved one, he learns very quickly that the girl is either the victim of an ex-con's manipulation or the brains behind the robbery of a major criminal enterprise. Whatever the truth may be, she is in mortal danger. Tracking the pair from the UK to Paris, then Paris to Asia, Adam delves into the murky and violent world of human trafficking and extortion, where he must draw upon the darkest corners of his psyche to survive.

Adam Park owes favors, and when an aid worker is murdered on the Greek island of Paramatra, one such favor is called in. Kai Pace's parents believe the investigation into their son's death is deeply flawed, and Adam is tasked with reviewing the police's conclusions and - if found wanting - identifying the real killer. On an island struggling to cope with the influx of refugees from war zones across the Mediterranean, Adam must battle corruption and ruthless smuggling gangs.

When Adam is retained to confirm the veracity of a young heiress' family tree, it sounds like the simple case he needs to break the monotony of life on a Mediterranean island. But it soon becomes clear that others wish to stake a claim to the girl's fortune, sponsored by an organization with one foot in the occult. And something as inconvenient as a private investigator will not stand in their way.
