Killinger is a maritime insurance adjustor
This means that his job is to not only find out what happened to ships and such at sea but also what the ramifications are. Succinctly, how much to fix it. The role of adjustor, according to the first book, requires impeccable character, immense knowledge of all aspects of seafaring and oceanography, and considerable expertise in International Law. Killinger is considered one of the best, often in demand, and always willing to help for fees which are, according to him, ‘never reasonable’.
Killinger is also a 6th degree Black Belt in karate who lives aboard a large boat with his two Hungarian pointers named Copper and Auric. Though he is 41 years old, he looks at least 5 years younger and his well-honed body 10 years younger still. Furthermore, inside that physique is a mind that is quite capable of seeing beyond the mysteries and the lies.
Killinger is helped in his business by Kimo, a Japanese-American born and raised in Idaho and now learning marine business with Killinger as well as studying the martial arts. Young and inexperience, Kimo nevertheless show potential and Killinger likes teaching him.
The money that Killinger makes is considerable and he loves to spend a portion on items to improve his boat home, including a fair number of erotic pieces which are as antique and exquisite as they are interesting.
When it comes to action, he does not particularly like violence but has no qualms about facing it. With his skills and his experience, he can handle his own in most situations and in the others, his brain can usually come up with something.
