Connie lives in a big farmhouse in Surrey with a couple of Labradors. There's a nuclear bunker with biological/chemical weapons testing pods downstairs. About five people in Britain know about it. Harry Pearce is one of them.
Connie started out as a secretary for MI5 when she was 19. In the intervening years she's become one of the sharpest, most resourceful, no-nonsense operators in the British security services. How? Because she knows all the secrets.
When the Ministry of Defence was going to de-commission the bunkers, she offered up herself as housekeeper. And now Harry needs them. In fact he needs her. And she needs the Grid.
