Scott Stiletto is an agent with the CIA.
He has been one for more than a few years by the time of the first recorded adventure but even before his time with the Agency, he had had a long and eventful career.
Stiletto joined the U.S. Army at nineteen in order to provide for his new bride, Maddy, who had just become pregnant. Through hard work and dedication he had risen in the ranks and become an officer and had chosen an especially challenging route to do so, making the grade to be a member of the elite Special Forces. But all that came at a cost to his family with so much time spent away from home. When his wife got sick with cancer, he retired from the military but when she passed away he was left alone. His only child, a daughter named Felicia, was furious with him for reasons he never understood and chose to have nothing to do with him. That left him with no anchor.
He had considered an offer to join a private investigation firm in New York prior to his wife's death but with her gone that line of work lost all interest. That was when the possibility of a job with the CIA came by and he took it. The extensive training at the Farm, coupled with his already considerable experience in the Army made him a powerful weapon to be used wherever was needed.
The sorts of highly dangerous missions that he will get with the Agency will help him cope with his depression over the loss of his wife but it will also continue to provide him reasons for not trying to reconnect with his daughter, a gap that will constantly weigh heavily on him.
As time goes by in the series, the troubles that Stiletto will have to face just keep getting harder and nastier which is a bad thing for him but even worse for his opponents because he seems to live off adversity - certainly he keeps getting better with practice.
