With the two jumbles at 1d and 24d, we have 2 unchecked in each....can I assume these must be the same letter?
(As it happens, same letter in both clues too)
Thank you Loge. I couldn't convince myself the infusion could become a verb but it makes sense now. For 7d, I didn't have the plural in my Chambers but the answer is comprised of three pretty regular parts and should have got there.
