Hi all, I've not posted for a while, but I'm always here reading your deliberations.
Definitely a hard one this week, so far as I'm concerned. 4d's a nice clue though, I thought - but only after Jazzgirl explained it :~) I'd been struggling with Wisden and the wrong kind of cricket.
Anyway, I'm still stuck on three that don't seem to have troubled the rest of you:
1d - French writer up tree
10a - Drama series
20d - What sort of mug?
Gentle hints please...
A-P
