"The Prisoner" walking tour

I've been meaning to do this since I arrived in London, but it's a once a year event, and I keep missing it! But at long last, I attended David Lally's walking tour of London filming locations for The Prisoner. I suppose this consolidates my place in the upper echelons of fandom, but I have to say it was really quite thrilling to stand...

In the corridor where Number 6 delivers his resignation at the start of every episode (a car park underneath Marble Arch)...

And outside Number 6's house at One Buckingham Place.
