Morgan Fox is a salvage expert.
He is no spy, doesn't want to be a spy, would much rather not have happen to him the sorts of things that happen to spies. Too bad he does not get to make those decisions.
When we meet him in the first recorded adventure, he is on the phone with his wife trying to explain that the job he was on in the Yukon was "safe". The way he was doing the explaining, it definitely sounded like he was having to the sell-job because his previous jobs of the type he was currently on had not been so "safe". The way she hung up on him spoke to how well she believed him.
Fox was doing the job because "he needed to do something to pay the bills - his heavy lift construction company just didn't have enough contracts at the moment to make ends meet. He was filled with frustration and disappointment at his inability to provide for his wife, to provide for their life." That desire to earn a decent life for the two of them will provide the incentive for him to get involved in several things that are most definitely not "safe".
Financial necessity is going to push Fox into working on one simple little job for the CIA. Of course it is never a simple anything with the Agency and once a fellow has done his good deed for them and pulled off a miracle, it is quite impossible to keep them from thinking of the guy the next time anything remotely like what he had done. Making it even harder is the fact that the money they offer is so darn attractive, it is next to impossible to say no.
Fox is described as a man in darn good shape, likely in his late 30s. He may be a civilian when we first run into him but we learn that Fox had served in Iraqi Freedom and had done more than one tour in Afghanistan so he certainly had experience with danger and with combat. This is a very good thing considering he will need all the experience, and luck, he can muster.
