The Places
Where everything happens... Mostly London, though... Selected places have pages of their own, because they need to, as there would need to be masses of information.

Brentford
Hanwell
Heathrow Airport (LHR/EGLL)/Feltham/Hatton Cross (Heathrow South-East)
Hounslow

White City/Shepherd's Bush
Home to the big meeting place. Westfield London West - White City. The general area is well linked to various places around West London.
Kensington/Notting Hill
'West Central London'. Home of various food places, including 'Whole Foods Market' and 'Four Seasons', where organic food and prize, excellent, delicious duck is presented for consumption. :) It is noted to be 'very' posh, very rich and very Tory.

The not very large area of Central London where most of the characters go to when they go to Central London.
