Hi, Rusty!
I only wondered if you were expecting your son this morning, because you were rushing out to get your bits and pieces from Screwfix!
But obviously I can see now that you just needed to do so, as to be ready for "whenever" he could come.
I have been looking up "Walls have ears".......well, it keeps me out of mischief!
It's rather interesting.
Apparently, Catherine de Medici had certain rooms in the Louvre so constructed that what was said in one room could be heard distinctly in another.
That way she became acquainted with state secrets and plots!
There was also a reference to Dionysius' Ear - a somewhat comparable situation!
I've finished the crossword...
I have two parses still outstanding.........25a and 4d?
