Nick Temple is an agent with the CIA.
The first recorded adventure takes place in the mid-50's, not quite a decade since the Agency was founded from the foundation of the previous OSS. Temple is quite proud, though he might now show it, to be a charter member of the organization having come over from the OSS when the War was over and the agency created.
As we first meet him, he is in his early 40's with short cut salt & pepper hair and already sporting a small paunch from his days sitting behind a desk rather than being in the field. The field is where he would rather be but with a wife and two children, it is not a place a family man should find himself. Not that the marriage is working out so well but at least not being gone takes away one of the complaints his wife has about him. His complaints about her have to deal with her having too much good looks and too little morality.
We learn that Temple has definitely paid his dues in the spy game. Born in 1917, he enlisted one day after the attack on Pearl Harbor. Some time during the next four years he would be assigned to the OSS and would have considerable experience in the European Theater. Once the CIA was founded, he would be assigned to Germany and would soon be named its Station Chief, holding that position for several years.
During the adventures we have of his, we find him going up against East Germany and its master, the Soviet Union on several occasions and even when he tries to expand his expertise with the advent of the Vietnam Conflict, he will always be drawn back to Berlin and her wall and her hub of spies.
