The arrest of a jewel thief leads Peter and Neal toward a much more heinous extortion case against adoptive parents. To catch the heartless mastermind, Peter and Neal dive headfirst into the world of high-stakes gambling to force the criminal's hand.

Neal and Peter must go undercover into the world of corporate espionage after a tech company's head researcher is murdered.

Wesley Kent's microchip firm's head researcher Joseph Hayes is murdered by poisonous overdose, presumably on account of his revolutionary invention. The duo goes undercover, but due to his major, Peter now gets the cushy alias of pampered rating agency accountancy expert. Neal joins the competitive junior executives in a cubicle, but gathers no less information there. After Mozzie discovers Peter has the music-box, he must accept to continue the Kate investigation officially, with a stuck-up FBI agent as equally unamused partner.
