Finished and I have the book title and how to alter the middle line but I'm stuck on four which I'd appreciate hints for (hints only, please, it's early days).
There's only one word that fits the letters I have for 6 down, but I can't fully connect it to the clue.
19 across is foxing me completely. I know one of the letters has to be O because of the theme, but is it the first one? (Though if it's not, it might invalidate my altered 15 down.
I'm also stuck on 24 down and 32 across, but I'll persevere.
Thanks
