Damon Thorne is an agent with the CIA.
Was an agent, to be more accurate, and as such his presence in this compendium is spy-adjacent at best. Still, he is interesting so I figured I would include him in this collection despite the fact that he has chosen to leave his employment with Langley and to make a living in a slightly different occupation. This new line of work, that of being a fixer, is no less dangerous than his last job but apparently it does pay considerably better. He still has, unfortunately for him, a knack for making very dangerous people want to end his life.
We are given the following as a blurb explaining Thorne's line of work: "Former CIA operative, Damon Thorne, is a fixer. He cleans up messes other people make of their lives to forget the wreckage his own has become. Whether it means retrieving a drug addict whose family is being blackmailed or rescuing a furball who's the subject of a custody dispute, Damon just gets things done."
Now Thorne works mostly for himself, albeit with a handler who finds the various jobs that he takes up. That handler is a woman named Trixie, a woman who according to Thorne seems to take pleasure in finding ever worsening places to meet to pick up assignments. In the first recorded adventure when he complains about this, she responds with "May the skin of your bum never cover a drum". I will leave that to you to figure out.
As we follow Thorne on his numerous adventures told in two books, we learn that he is now primarily gay, especially after his encounter with and subsequent partnering with Jude but Thorne's history in the romance department is a collection of both male and female relationships. His last important one was with a woman named Kelsey whom he married and produced the much loved Faith. It would be their loss that would drive Thorne from the CIA.
