Sam Jameson is an agent with Homeland Security.
Samantha is a woman in her early 30s. She is described as beautiful, sexy, deadly, capable, and snarky. The last one is my word for her but it certainly fits. She does not take stupid people well. She does not take so well to authority, most of whom also fit into the first group. She does not take argument well because it so often is with that first group and things would go so much better if people would just clam up and do as she says. On a lot of people this would be bad but with Jameson, it is a good idea because this woman is usually right.
When we first meet her she is described as: "She stood five-ten in flats. Her impeccable professional attire couldn’t hide her more-than-impeccable physical condition. She was stunning, brilliant, magazine gorgeous, and efficient. She had red-blonde hair and piercing green eyes that seemed to leave burn marks."
Professionally, it is said that "through no concerted effort of her own, she had come to be treated with deference, even reverence, by most of her fellow counterintelligence officers at the Department of Homeland Security. It was a tough crowd, but her natural gravitas was impossible for her colleagues to miss. Over the past five years, Special Agent Jameson had assembled the beginnings of what promised to be a stellar career in the counterintelligence service."
One interesting aspect of the two previous statements is that when she speaks, either her looks or her presence gets attention in any group. Then when she throws in a line which proves her father's comment about her 'sailor's mouth', the effect is often stunning. "Vulgarity was a bit incongruous coming from a mouth as gorgeous as hers. But it tended to have the desired effect."
The last important part of Jameson that should be noted is that she gets results. She has a very keen mind and a terrific instinct and together they make for a highly potent weapon.
