Another interesting Bowers file. Patrick is still chasing Basque and has some promising new leads when he is called to a double homicide by Director Wellington. The murder of a wife and daughter and the husband is missing. Nothing is what it seems as Patrick, Lien-hua, & Jake investigate the missing husband, an assassin, an eco-terrorist group looking for an abandoned underground secret military facility. Happening near where his brother lives, Patrick works to make peace with his brother, counteract Tessa's unusual behavior, & bond more with Lien-hua. Old temptations rear their head and a game of cat & mouse with the assassin has Patrick on his toes. Not as good as the other books. Too much technical jargon & too pat of an ending with the murderer. I will still finish the series though
