James 'Max' Maxted is an aviation entrepeneur.
The year is 1919. The Treaty of Versaille is in the process of being agreed upon, drafted, and then signed. Europe is finally at the end of four horrific years of combat and it is time for everying to resume 'normal' lives.
For young Maxted, that means finding a career outside the Royal Flying Corps, a place where he had made a name for himself with a good deal of superior flying and not a little luck as an aviator during the War. The love of flying that he had had years before the conflict began took him easily into the Corps where his experience in the nascent field of aviation and his quick reflexes and keen eye made him a natural to take on the German version of the Corps. He would find that new line of work in the surplus of planes no longer needed for combat and available for purchase and resell to those seeing other uses for the items.
But that endeavor would be put on hold when his diplomat father dies under very mysterious conditions in Paris and Maxted is unwilling to accept the official findings. That in turn will lead him to get involved with his own government's intelligence agencies as well as those of Germany and even Japan.
