I know this.... I know this.... a little clue?

Thinking about a clue for later :-)

Harley Street?

Very, very close. Harley St runs off this street and this is an E-W rather than N-S street. You should be able to get it now, I think.

ah... Wigmore street, the windows of the medical centre, at the corner of Wigmore and Wilpole streets?

Precisely correct, benestrada (although you mean Wimpole not Wilpole :-) Congratulations, well-spotted. Hope you're enjoying the game!

Did enjoy it Jen! and yes, of course, I meant Wimpole... Now I need to work out your latest (sailing through a blue sky) I knwo I've walked by it so many times, but it just eludes me at the moment :-)

It's much less central...
