Chad Hunter is a weapons engineer.
As a wealthy man comments in the first recorded adventure of Hunter, he is "...the best weapons engineer in America. Graduated from Colorado with honors, worked for nearly ten years with Colt, three of which were spent with von Herz. Then you returned to the states and worked for the Army for a little over three years. You left government employment a year ago to work as a private consultant. A free agent, I suppose." The "von Herz" mentioned is a German arms designer of major reputation so the fact that Hunter was able to work with him for three years says a lot for his skills.
While he is very gifted and trained and well regarded in the arms industry, he is not, if the pun may be excused, loaded. His consultancy business barely pays for his simple lifestyle but since it is simple, he is content and not really looking for something to bring in the big bucks. If he had been, he likely would have remained with one of his former employers.
What Hunter likes more than financial success is the work. He truly enjoys the mechanics and the science of creating an instrument that can hurl a tiny object a very long distance at a very fast speed. The fact that the intended recipient of that object is likely another human being whose demise is the intention is not lost on Hunter. He had long before stopped using his creations to hunt animals no matter how tasty they might be; the animals did not have a chance and that did not sit well with Hunter. When he hunts for food now, he uses a bow and arrow.
Joining Hunter in the three adventures are two people worth noting.
The first is Frank Baldwin, an older man and an expert at optics. His revolutionary scope was what brought the two together and their instant friendship has helped their working together. Baldwin is not quite as active as Hunter but his experience and good sense are invaluable.
And then there is Sirena. A beautiful woman holding dual U.S. and Israeli citizenship, her background is one of mystery with a good deal of her young adult life kept hidden by the National Security Agency. When the cloak and dagger business starts to envelope Hunter, she is there to be a guide and she is very good at handling herself in that shady world. She and Hunter become far closer than friends.
