Tucker Wayne is a freelance agent.
He has no shingle hanging outside his office proclaiming that profession for a couple of good reasons. First, he has no office, or home, or permanent place of residence as he is far more interested in just moving about. Second, he has no real job or a desire for one any more so to say he earns his living as a freelancer is not really true. He just picks up the odd job here or there and on occasion that means doing something for . Other times it might be as a security consultant. And on more than occasion, it is just stopping nasty people from doing nasty things. In one adventure when finances required him to act as a bodyguard, he summed up his actions by musing "his job was to protect the bad from the worst".
For many years he served honorably in the U.S. Army Rangers, rising to the rank of Captain. His specialty was tracking and he was very, very good at it. He was taught well how to be extremely observant and to see tracks and other signs of passing where very few would notice anything. He learned that just seeing was not enough, though, as it was necessary to think like those he was stalking. Where would they go or hide? What would they do or plan? Figuring out where the intended would likely be helped greatly when on the hunt. Also helping even more is the incredibly gifted dog, Cain. A Belgian Malinois, aka Belgian Shepherd, Cain had been with Wayne for many years and together they comprised one highly effective team.
Originally the twosome had been a trio, the third part that of Cain's litter-mate, Abel but that dear comrade was severely injured during a mission and Wayne was forced by approaching combatants to leave his dying friend behind, something that continues to haunt him. Since then, it has been just the two, friends and partners and a team. "They'd worked together, eaten together, even bunked together."
When Wayne finally decided, as he entered his 30s, that he had served enough in the military, he said his goodbyes and left, taking Cain with him. It was not strictly permitted but he did it anyways. Since then he has taken the occasional odd job as funding forced him or inclination took him but mostly they roam the world and take what life pushes their way.
