So I went down..
Dark dank and full of cobwebs, It was obvious that no one had been down in a while. I borrowed Gordon’s (@gt_p) camera and took a few photos. There was a glimmer of light at the end of the tunnel. Perhaps I should draw a parallel to Bletchley Park’s use of social media and the hope that all will come good in the end.
On this occasion the light signified that this may well be an innocent service tunnel linking departments in a now run down and disused building. Not as we had hoped, a shortcut to the pub.
The mystery continues and the hunt still goes on.
Or better still make a donation to The Bletchley Park Trust
