Found this puzzle really tough. Still struggling on a few.
15d (B) Male people's failure to move house abroad in twice three-penny opera (10;10) I have T?N?H???E?
23d Merry Meg taken from book, one that buzzes loudly for food (4;4) I have ??G? and ??E?
22a B Animals in 15(B) 23down(A) in 14 across(A) (7) ??L?R?M
Thank you Calibax. I thought of this but think it probably starts with an F and I can't see the animals in the answers to the other clues. Very difficult!
