Simon Leonidovich is a courier.
Though his real first name is Boris, he is only called that by his assistant, Lara, who is also his sister, and only when she is irked at him. Together they comprise Worldwide SD, the "SD" standing for Special Delivery, a small but highly profitable courier service well respected for always delivering the package.
The items that Leonidovich is willing to convey are wide ranging, from art works to human organs, from confidential corporate papers to nuclear materials. He will not haul anything illegal and he will not skirt any international safeguards as he runs a totally legitimate enterprise. What he will do is use the very latest in technology and more than a few years of experience to make sure the items gets from where it is to where it should be.
He doesn't like guns and isn't a big fan of fighting but he does have one unique ability that helps him out of trouble: he notices the little things and remembers them. His eyes are always on the move and he seldom misses anything. Just seeing things is not always enough, however. A person has to be able to see several apparently disparate items and realize that they really mean something together, something that can endanger the assignment. At this Leonidovich is an expert.
He is not an espionage agent but he fits into this collection by the fact that his duties take him around the world and he reluctantly finds himself involved in matters of state or international consequences far more than he would ever want to. Moreover, the bad guys that he encounters play on a global stage and they seldom play nicely.
