Plot summary

Sean King, financially hard-pressed and trying to help his professional and platonic partner Michelle Maxwell, is forced to seek an assignment from his ex-girlfriend Joan Dillinger, a fellow ex-Secret Service agent who runs her own private investigation agency. Joan gives him a case based at a laboratory, investigating the murder of a scientist, Monk Turing. During his investigations, he stumbles on Camp Peary, the CIA training facility which leads him to a more complicated investigation, on which he works together with Michelle, who has attempted suicide after a psychological breakdown. He encounters Turing's autistic daughter, Viggie Turing, who is also extraordinary talented, but is willing to trust only Michelle, and hates Horatio, the psychologist who is treating both her and Michelle. Eventually, Sean and Michelle solve the case, but not before being tortured by their enemies. Sean gains a treasure, but generously shares it with others even though he is in financial difficulties.
