I've just done a bit of googling and found out that the "Forbidden" part of Dun Darach was originally called "Lady Q's" and was a brothel.
I got a very early copy, and mine said "Lady Q's" (not "Ladyo's" apparently) and NOT "Forbidden".
I still couldn't find a way in, but some early copies must have got out before the sign was changed to "Forbidden".
Still the intriguing possibility exists that some may have got out with the centre bit still in.....
