Multimillionaire Stone Barrington is a former cop, lawyer, partner in a high-profile New York law firm, and a veteran of several different government employers. He also has served in political appointments and is reprised by Stuart Woods in TREASON.

Stone is surrounded by his usual coterie of friends and acquaintances in the escapades in which he finds himself partaking as he solves his latest mystery. Someone has reported a mole in a classified agency, and it is up to Stone and his crew to track down him or her. Obviously, this individual has nefarious reasons for betraying his or her country, and the faster he or she is found, the safer everyone will be. Stone has dealt with this person in the past and understands that he has his work cut out for him.

In TREASON, Stone is a consultant, and his long-time affair with Holly Barker is still in place. She is now Secretary of State and is working with an agent posing as a writer so he can snoop around looking for clues that will lead the team to the traitor. She is also planning a run for president and has to be careful about how much she makes public about her life. Their relationship does not prevent Stone from continuing his womanizing pursuits. Few ladies can resist his charms and the extravagance he presents to them. His wealth and reputation make him wanted by one and all.

An airplane broker named Callie Stevens sells Stone a custom airliner on a whim. When they go to the airport, they find a slashed tire on the plane. Stone deduces that the woman’s ex-husband is probably the perpetrator. She doesn’t know what to think. Appearing in major roles here are Stone’s friends, Dino and Viv Bacchetti. He is the police commissioner and she his faithful wife. They all decide to go to Paris for a few days, and Stone invites Callie to come along. She does, but leaves early to return to New York and sell his old plane.

Stone meets another woman at a private dinner, and she accompanies him home. She is the neighbor of one of the men who Stone is interested in as a possible suspect and is able to offer some information about him. Stone sees him the next night in a restaurant and notices that he is spending tremendous amounts of money, despite his reputation for being tightfisted. Next comes an invitation for Stone and his friends to have dinner at the man’s house. They all go.

Since Stone owns several homes with servants around the world and has his own plane, he can pick up and go anytime he pleases. He also is in contact with all of his connections no matter where he is and is ready to follow whatever instructions he receives on his scrambled phone line. This keeps readers up to date on Stone’s latest assignments, which adds to the narrative’s fast pace.
