Tony James is an agent with the CIA.
Absolutely not true! Still he is associated with the CIA despite really not wanting to be. He is because, well, because they want him to be. They know something about him they want to use. They want to study him and learn from him and figure out how he is able to do what he does so naturally so they might be able to do it as well. All in defense of the country, of course. No personal agendas here.
James does not believe it, of course. How could he, considering the very ability they are so interested in. The skill was "to instantaneously sense dominant core character traits". Which meant that upon meeting someone, James could get a really good idea right away of what kind of person someone was. From then on, if that person tried to inveigle him into something, he could glam on to the fact that flattery or coercion was being used, not truth.
It was a skill a lot of people would love to exploit. It was a skill a lot of people would kill to prevent it being exploited on them.
