Devin Gray is a countersurveillance expert.
He is not a CIA operative even though in the fact sheet above I list that organization as the one he is associated with. It is listed there because even though he isn't an agent, his estranged mother, Helen, is. Or was.
On our introduction to him he is working for a private company named MINERVA, described as "a Beltway-connected boutique countersurveillance-counterespionage firm". He is on his first field operation with them and he quickly decides he might not be with them for long since on that assignment he took on three members of the opposition and left them hurting and unconscious, not exactly the low-key approach he was told to take. And not the sort of non-combative role he was expected to have.
Certainly it was quite a bit different from the work he had once done for the FBI, twelve years spent 'ghosting' foreign intelligence officers and spies for the Bureau's Special Surveillance Group. Considering his history, he knew he was lucky to now be employed by MINERVA. "Being the son of a psychotically paranoid former CIA officer came with a few drawbacks. Losing his security clearance, a requirement to remain employed at the FBI, had turned out to be one of them. Going radioactive was another. A lot of good people at the Bureau cashed in serious favors just to get him through the door for an interview. Quitting MINERVA this soon after joining would ensure he never worked in the counterintelligence industry again".
Returning to the subject of his mother, who remains a factor in these adventures in one way or another, Helen Gray is a woman obsessed. She had acquired a personal albatross and devoted her life to destroying it; in doing so she knew she had "thrown away her career, destroyed her marriage, and - most painfully - alienated her children". It will be this obsession and the fallout from her actions that will play such a major role in the career path of her son, Devin, and the adventures we have of him.
