With the last Guess Where Tube 12 two people got it right it was the clock at King's Cross Tube station at the top of the Northern Line escalators to be exact.
This week try to guess the exact location of where I spotted this London Underground mouse. It's possibly the best picture of a Tube Mouse, I've taken as the little thing was running right on the platform by my feet.
As it's the festive season and I'm feeling generous and this one IS extremely hard I will give a prize (it helps to know your Tube flooring). I've turned comments & tagging off the Flickr picture and the only way that people can guess or enter is through this blog post. So try not to look at the comments in front of you before making your guess.
Apparently, an estimated half a million mice live in the Tube system so your chances of seeing them should be pretty high.
The prize up for grabs is my favourite Tube book (Neil Gaiman's Neverwhere) which actually features King Rats on the Underground (one's even on the cover of the book), so seems appropriate to link back to their mini cousins! I often see people reading this on the Tube as it's a great book and should be required reading for Tube commuters.
You have until Sunday 18th December 11.59pm (UK time) to enter. Make your guesses by then in the comments below and either leave your blog or twitter name or email address so I can get in touch with you if you're the lucky winner. Anyone who just enters as "Guest" with no means of identifying how to contact them, won't be included in the contest. The person who is the most exact will win & if more than one person guesses the same correct place, I'll put names into a randomizer & select from there.
