Lights
This is in Fenwicks, the corridor to the side of entrance on Northumberland Street which takes you past the florist into Yo! Sushi. Love the lights drawing you down the corridor.
Surprise coming on Monday, although those who read all the comments (or who read everything on twitter!) will have figured it out. Feel free to speculate 
wow fenwicks has certainly changed since I was last in there.. looks lovely though. Baffled by this surprise on Monday as I do read all the comments posted and really aint got the foggiest idea wots instore !!
Hilariously I went back to the day in question and the person in question said what it is, didn’t just allude to it as I remembered. I’m quite excited!
engaged the brain now … I got it !! Bingo !!!
I must walk through that way next time I’m in town it looks lovely.
I haven’t a clue what to expect on Monday though.
I meant to say the other day, how much Fenwick’s has expanded over the years. I wonder how long it is since this corridor used to be a little alleyway to an entrance to Fenwick’s food hall. It was between Fenwick’s main store and Finlays tobacconists, who were next to Boots.
