Nicolas "Nick" Fox is an international con-man and thief. Kate O'Hare is a decorated F.B.I. agent.
For several years prior to our meeting this fascinating "couple", O'Hare had made it her life's mission to find and apprehend Fox. She became the world's leading expert on the handsome debonair shyster, knowing what he would like do next and where he would probably strike next but though she got very close a few times, he was just a tiny bit faster and luckier.
Then in the very beginning of the first recorded adventure, we find that speed or luck come to a crashing end, literally, as O'Hare used Fox's tactics against him, setting up a delightful con which drew him in and when he was making what he thought was his triumphant getaway, she plowed into his car with a bus. Now, she got a minor ding on her record for the misappropriation of the bus as well as the t-boning of a suspect's vehicle but she got her man. Fox was in jail.
And then he wasn't. His con of the U.S. marshals in charge of his transfer could not be held against O'Hare but it still irked her tremendously and she put her entire energy into figuring out where he would go to lie low. She figured it out. She snuck into the locale, She cornered her man yet again.
That is when her boss stepped out of a side room. And her boss's boss. And the lives of both Fox and O'Hare would change forever.
The idea was likely Fox's. The fed leaders might have other thoughts on that but O'Hare always put the blame on Fox. The concept was to use a thief to catch a thief. There were a considerable number of high profile and high influence miscreants who were able to use their power or money or influence or evil to get away with some very nasty things and the Bureau was unable to do anything to stop it. So, perhaps a good con might lure them into a snare. Who better, Fox reasoned, to con them but one of the best in the business.
The Feds were not naive, of course. They had no illusions of Fox suddenly turning straight so they needed someone to watch over him, to help him in these cons but to also be able to predict if and when Fox might disappear.
So a partnership of two opposites was created. Fox is a world-hopping connoisseur of fine dining and luxury living. O'Hare is a big In-n-Out fan whose idea of sinful pleasure is a Toblerone. Fox is a crook, trained almost from his childhood to con and swindle and steal and BS his way through life. O'Hare is a former Seal who is a by-the-book as one can be, trained by her father, a former covert operative, to be able to kill a man numerous ways with a paperclip.
In this new team the two will pull into the business several people who help bring the elaborate cons to life. Boyd Capwell is an actor so devoted to his art that he is almost impossible to work with. Willie Owens is a woman with massively augmented breasts who can drive anything with an engine and loves doing so at all times, even if she does not have a license or permission. Jake is O'Hare's highly trained operative father who is bored with retirement and loves to step in to help with the odd rocket launcher as needed. There is an electrician expert, a superb set builder, and a special effects man to round out the team.
These people could easily, and rightfully, tack Mission: Impossible on their resume, if they were allowed to tell anyone about their illegal but highly effective projects. They are not permitted but we can still read about them.
