a couple of points re. Darling

'the site 'near St Paul's' is Lord Holford's Paternoster Square
development, now redeveloped beyond recognition. Christie and Harvey are
outside of, and go into, Sudbury House (demolished 1998).

are you sure the tube station is Notting Hill Gate: logically Christie
and Bogarde should be at Bond Street Station, having just left a Bond
Street gallery, to get a train for Notting Hill. Furthermore, there aren't
the long escalators at Notting Hill that we see them descend.'Roland-Francois Lack
