Helen Matheson (if indeed that is her real name) is an intelligence operative of some sort. Her past is murky, although she has claimed to have been involved in the UK secret services. However, her unit was privatised and she now works for anyone who will pay her. Her client list is a closely guarded secret, along with any details about who - if anyone - she reports to. Her income stream appears to be tightly controlled, judging by the quality of agents she is able to recruit. Either that or she is an exceptionally poor judge of character.
She is glamorous in appearance and enjoys the effect she has on the people she comes into contact with. Tom Winscombe, for example. She is also completely ruthless and has been observed to kill without a second thought.
The following is a partial list of known agents who have worked for Matheson at some time:
