Location #3

On the deserted roof of a Northolt multi-storey car-park, I waited by the balustrade. In the rear seat of the car Vaughan arranged her limbs posture of the dying cashier.

I can't find any evidence for a multi-storey car park from google earth, so maybe a poetic representation might be worthwhile... a collage approach possibly, find a derelict plot of land in Northolt and superimpose a suitable car-park... virtual town planning, after all as Ballard says the job of fiction is nowadays is to recreate reality!
