Eric Baker is an agent with the CIA.
Because of a horrific incident that happened to her sister when they were both young, in which the sibling, Claire, was kidnapped and held for four years, Baker is determined to never be unable to take care of herself. In fantastic physical shape, Baker has also earned black belts in three different martial arts discipline, not to mention the firearms training she got when she joined the Agency.
That same event also make of her a fervent champion of the underdog, especially children, and anyone who would inflict harm on a defenseless person and then come into reach of Baker will find the meeting unpleasant if not lethal. Baker does not accept excuses or apologies where kids are harmed.
It is easy to see from our first meeting of Baker, helping out in a training session of Agency cadets, that Baker could be said to have anger issues. Even more, though, is the intense determination to never, ever, be a victim; never to let someone have that kind of power over her.
Baker had worked at the Agency for a few years overseas running agents but when her mother was diagnosed with cancer and died soon after, Baker returned to help her sister and her seven-year-old niece, Janie. When we meet, her job consists of teaching "Ethics and International Relations to twenty-year-olds while keeping her eyes open for potentially violent anti-American sentiments among the foreign student population" at Georgetown. She got the gig not only because of the Agency's pull but also because of the PhD in International Studies she had earned before joining the CIA.
