Carlton Dial, aka the Fortune Hunter, is an adventurer.
In days gone by, the terms adventurer and fortune hunter were practically synonymous. Of course, the former would imply seeking to experience something - adventure - while the latter would mean achieving something - a fortune.
In the case of Dial, the description used for him is that of a former government operative whose previous line of work constantly involved very dangerous assignments taking him to very deadly locations to go up against very treacherous people.
When we meet him he has switched employers to work in the public sector as an agent for the Intercept Corporation, billed as "a high-tech global recovery organization". Based out of San Francisco, it is job of Dial as well as his partnee, Harry Flack, to be sent to inconvenience different people all over the world who possessed things that Intercept's clients did not want them to continue to have, be it classified documents or stolen property or top-secret weapons systems or something else entirely. It was Dial's role to get in and get out with the item(s) in tow and for this Intercept would charge a quite handsome fee, a good deal of which would go to Dial.
According to the terrific description on Wikipedia: "Dial is portrayed as a suave, charming and self-assured spy, similar in style, dressing and witty remarks to James Bond, who uses his quick wit and sense of humor to get him out of many precarious situations. Dial performs his high-risk assignments with deadly seriousness. Determined to keep his perfect success record intact, he depends upon split-second timing and an astounding array of sophisticated electronic gadgetry - not to mention his partner, Harry. Dial wears a special contact lens with a built-in camera and an electronic earpiece, so Harry can see and hear everything that Dial does. This also allows Harry to speak with Dial, relaying information to the agent immediately, from the safety of the home office."
Dial is a handsome, athletic man in his very early 30s, rich dark hair and near constant smile.
