Mike Anson is an agent for the British Prime Minister.
He leads a very small group which is tasked by that country leader to be the main force going up against a nefarious organization dedicated to conducting acts of aggression and sabotage on the United Kingdom. That group is named ARKAB - the meaning of which has escaped me - though it is sometimes referred to as the 'Big Enemy'. Exactly what ARKAB is or how it got organized is also a mystery although no one working for Anson has any doubts it draws its marching orders from someone important behind the Iron Curtain.
Anson is officially a Major in the Royal Marine Commandos though he is usually found in civilian attire, except for those times when he makes his occasional trips to confer with the PM - leading to the meaning of the collection of these adventures since to have these meetings his 'destination' would naturally be 'Downing Street'. On those occasions, he very much appears on every manner a dedicated, professional soldier. Interestingly, while we know that Anson makes these forays to the PM's residence, we never actually meet that leader nor see the two of them together.
That small retinue of coworkers consist of:
Jacques - a former French Resistance fighter now residing in England.
Sylva - a gorgeous operative originally from Czechoslovakia.
Colin - a British university professor.
Phoebe - an officer in the WAAF whose function appears to be logistics as well as officer manager.
The leader, Anson, is a good-looking man, obviously quite fit since he is a Marine officer, likely in his early 30s with regulation short black hair and a somber look that does, however, often look as though he secretly finds things a bit amusing.
