many thanks for your posting. You are quite right. I regret to say that I mis-read the sentence...."All other across clues are normal....", as " all other clues are normal". I sincerely apologise to yourself, other threaders, and, in particular, the compiler, who maintains his track record of accuracy.
I must eat humble pie (or the French equivalent)... though not sure where to fit this course in!
I thought it was a brilliant puzzle - not the most difficult but thoroughly enjoyable.
