The closest I can get on your letter frame is

Hi Margsy
I do not know the answer to 10d, but the solution is two words, 6 and 7 letters. A popular breed of English dog.
When is summer arriving?
James

The full clue is ....retractable roofs over each of these playing surfaces allow the championships at Wimbledon ....tennis courts is your answer

Margsy, you need to make sure you have given us the whole clue.
I spent quite some time - and Fresco probably did too - trying to find a word for retractable roofs.
You know I love to help, and the more challenging the better, but that was a little too difficult.
