Cameron Niven 'Cam' Gordon is a British private investigator.
He runs his own small detective agency named Gordon Investigations Agency (GIA), based out of Glasgow. It was just a two-person operation but it turned a nice profit and it had a stellar reputation.
The reason for Gordon's membership in this compendium is somewhat explained by the fact that the GIA has its office down the hall from a lawyer with the bizarre last name of Deathstone, a man who had a direct line to "an obscure British government department" decidedly a part of that country's intelligence community. It was Deathstone who convinced Gordon to set up the office near his and it was he who made sure that Gordon's high security clearance was still in effect. Needless to say, when Deathstone - or someone from that department - had need of a qualified investigator who was outside normal channels, Gordon was the man that got the call.
It is important to mention here that Gordon obviously appreciated the business but "a summons into Mr. Deathstone's office was generally the prelude to a particularly awkward job of work".
Gordon is said to be "nudging thirty years old", which is interesting because he has already been in the British Army, serving for a short time as a junior artillery officer for a while, and then after getting out was a policeman for a time, likely putting in a couple of years as a detective. It is for that reason that I think the "nudging" might be from the far side.
He is described as being 5'10" with a stockily build, Scottish by birth, with dark hair and the kind of face more likely to be called rugged than handsome.
