In his latest case, Sonchai is paired with young, female inspector Krom. Like him, she's an outsider on the police force, but she is socially savvy and a technological prodigy. In the midst of a typhoon they witness a deadly demonstration of super-human strength from a man who is seemingly controlled by a CIA operative. Could the Americans really have figured out a way to create some sort of super-soldier who is both physically and psychologically enhanced? Are they testing it, or him, on Thai soil? And why is everyone, from the Bangkok police to the international community, so eager to turn a blind eye?

The case will take Sonchai to a hidden Cambodian jungle compound for ageing American vets where he will discover exactly how far a government will go to protect its very worst secrets - both past and present. It is also a case that will shake Sonchai's world to its very foundation and may finally force him to confront his lost father.
