David Reece is an agent with SG9.
That is a sub-division of the British Secret Intelligence Service, or MI6 as it is often called. The designation stands for Secret Intelligence Group Nine but people working for this relatively new section just call it 'the Department'. It is a covert organization, such that it does not like to be talked about and is known by only a few. It has its secret headquarters in a "three-story flat-roofed building located inside the perimeter fencing of London City Airport" with a brass plaque on its entrance proclaiming it to be "Business Sales International".
SG9 was founded shortly after the July 7, 2005 London bombing that took the lives of 52 people. Its members were pulled from all the various British covert agencies as well as military and police ranks; the search conducted by the Deputy for Subversive Activity, Jim Broad.
Reece was selected because of his impressive record of service for 23 years with the RUC Special Branch. "He'd been a successful recruiter of agents and through the agents he had under his control had saved many lives and, on many occasions, prevented terrorists succeeding in their terror campaign. His skills were second to none: specialist firearms, bomb making and disposal, recruitment and training of new agents, surveillance, counter-terrorism techniques, interviewing...Reece was considered one of the best due to his ability to adapt and learn on the spot."
That dedication had cost him two failed marriages including "two estranged sons from the first" and a bout of trouble with alcohol before turning his life around. Now he is a loner who prefers, when not at work, to keep to himself.
