All done, including the replacements, and the grid fill was quick, except the NE corner. But I cannot parse 6 down. I assume the definition is the last 4 words, but where does the ditch come in?
Smithsax at #54, can you give me a final push, I can't see what goes in 12a to give 'teeth' at 8d.
I have changed eleven cells already elsewhere. So six of these seven should change? But none of the obvious names fit.
Ok I am finished.
Did not enjoy the endgame, having decided the message ended with six extra words...only to find it ended in a mix of five extra words and a rogue letter too! Why?! Brain ache.
