Hi Krypton27, I too am struggling this week. I don't have either of the clues you're looking for. I have the letters you have but I don't even understand the instructions in the little box at the top.
I found out that St.Custards is a fictional school but still can't solve the clue.
Lol. I really think I should try a bit more on my own first but I'll give you one clue down, 7d. Sets of 10 - Set D &c (7). I think the 3rd letter may be C.
Hi K27 - it really is a stinker this week - the only other ones I have are
22a - osteoma (anag of to some a)
24a - erato (muse)
7d - dectets (set of 10 musicians)
12d - woesome (only thing I can get to fit!!)
Thanks HW
Had some of these but not the dectets . Just identified 'gutta' for the drop ball so we only (!) have the goddess and the country (india?) still unsolved.
