That’s the one!

We knew it was there, the problem was the gap to look through was not in line with the gap between floor and ceiling.
Phone to the rescue and we now know where it is, trouble is we can’t reach it or see it to pull it out with a hook on a stick.
Luckily one of our geeky members had a tiny camera on one end of a flexible rod and a screen on the other. Not exactly job done but at least a viable alternative to a hole in the ceiling!
