Graham Wenby is an agent with Interpol.
He operates "in the shadowy world of a little unknown section of Interpol working across borders and more akin to MI5 than the police." We also learn that he "worked ... on special cases, always undercover, and usually working on his own. He wasn't a conventional policeman, and didn't always do everything by the book. Normally he was in danger, looking for terrorists or highly sought after illegal immigrants, or underworld masterminds". We are told that "He wasn't the normal Interpol employee. They worked with national police forces, but he worked without borders. There was either too much corruption or too much red tape in many of the places he was required to operate in. Inevitably he was therefore required to work undercover and to survive it was important that his story was a good one and that .every detail was plausible".
He tells a young woman that he is 32 years old and since there would have been no reason to lie, we will assume it to be true. He is described as "good looking and well-built he attracts women, and women attract him sometimes to the detriment of his final goal. Orphaned at birth he has no family and no wife to consider or cloud his conscience, which means he sometimes steps over the limits".
When not on the job, Wenby apparently likes to dress nicely. In the second adventure he has to shed what seems to be his normal apparel and that consisted of an "expensive tailored suit jacket" with a silk shirt, hand-made shoes, silk socks, and Calvin Klein underwear. Toss in a Gucci watch and you have an ensemble which shows a person who likes finer things and will spend what is necessary to get them.
Joining Wenby on both of the two recorded adventures is Sergeant Kelly Braniea, a gorgeous woman who is also extremely capable of working undercover as well as being quite able to take care of herself.
