Raymond Ingelram is a hunter.
For much of the two-book series about this British citizen, that is largely all you know about him. In the first adventure, you do not even know his name, first or last. He does not bother to tell anything of his past for the longest time except to admit that he was of the gentry, holding enough money from an inheritance to indulge in his favorite pastime, hunting.
It is almost a surprise to Ingelram that he was at all involved with German agents in the days before the Second World War, coming as a result of a spur-of-the-moment decision of his while hunting in Poland. He had hunted game all over the world and the whole of Europe was well-known by him and he was quite comfortable traveling all over it so when the fancy for a different type of target came over him, he felt completely at ease crossing the border into Germany (unnamed for a long time but later admitted).
That country he snuck into had a dictator, well loved by that nation but feared and despised by the rest of the continent and Ingelram's inspiration was that the world would be a much better place should he use his shooting skills and eliminate the man. It was only much later that we learn he had a more personal reason than he remembered for wanting the dictator dead.
Because the initial action was spontaneous, he did not plan very well his actions before and after but then usually the game being hunted is not in charge of a nation with a cadre of followers protecting him. As a result most of the first adventure is his paying the price for his attempt.
The second and final adventure comes a couple of years later when the world was fully involved with war and Ingelram decides another attempt was in order. It also does not go as planned but the experience the man had gained the previous couple of years and the dedication he now possessed to fight the dictator and his minions causes him to take further into a totally different set of troubles.
Through the two books, we learn so very little about the man's background and upbringing and life before the affair started. But through the pages we learn a great deal about the man himself.
