George Preston is an agent with the British Secret Service.
He is the one with, as the title of the overall series of adventures states, The Finger On the Trigger. That trigger in this instance is any weapon that Preston might be able to get his hands on at the time. The purpose for having that finger on that trigger is to kill Adolf Hitler.
It is near the start of World War II. The beginning of the quest by Preston, an endeavor which will earn for him the nickname of Phantom, will take place in June of 1940. Preston, already an experienced operative with the Secret Service, had put forth his audacious idea to bird-dog the German Chancellor and find an opportunity to dispatch him.
"I worked as a journalist in Germany until the outbreak of the War," Preston explains to his superior. "I know it like the back of my hand. I also know France well and our intelligence people reckoning that Hitler will be there soon." Preston will go on to explain that his hatred for Hitler was a personal one. His younger brother, Ted, had been in Austria some time before and been arrested for spying. Despite an appeal to Hitler, Ted died by firing squad and Preston had a new mission in life.
Preston is likely in his early-to-mid thirties, having short brown hair atop a strong, determined nearly handsome face. He will prove to be as determined and steadfast as he gave his supervisor to understand and though he will not actually succeed in ending Hitler's life, over time he will cause considerable trouble to the war efforts of the Third Reich by eliminating more than one of their top military leaders along the way.
The adventures of Preston will last the length of the War and will see Preston travel all over Europe from France to Germany to Poland to the Ukraine and back to Germany. Months will turn into years but his determination will never falter.
