Rupert Brett is a part-time agent for British Intelligence.
He definitely does not want to be but when you find yourself in a bit of trouble and men from the covert side of things offer to help in exchange for some small things here and there, well, you would be foolish to not take it. Brett is many things but not foolish.
He is eager, brash, a tad too naive, and truly wet behind the ears. He is also keenly observant, extremely intelligent, quite gifted in many ways, and determined to make it in the City. His chosen area of employment is commercial property management and we first meet him as he is applying for a position with the large and still growing firm of Cowl Rubens in the West End of London.
The young Brett we meet initially is 22 years of age, "just over six feet tall, fashionably cut dark brown hair, striking blue eyes, a full mouth, and an expression of assurance that anything was possible". As the adventures progress over the years, we will see him age, obviously, and the assurance will fade a tad while his determination will remain fixed.
It will be in the first recorded adventure where Brett will encounter the trouble that will eventually lead to his introduction to Intelligence work but he finds that once the cloak-and-dagger fellows learn of your skillset, they will not hesitate to call on you for this and that. And as Brett's star rises over the years and his place in the financial hierarchy improves, his ability to be of even more assistance will grow to and those who job it is to know things will know how valuable he can be.
Luckily, his troubles will also throw him, after a time, into contact with Chris Adams, Sergeant in the 22 SAS, who will be told to work with Brett and who will provide the much needed survival and battle skills that Brett, for all his keen intelligence, is very much lacking.
