Hi Chris
Many thanks for your explanations. I still can't see 20ac, but maybe the penny will drop sometime. I didn't spot the hidden in 25ac, though I wondered where it was as Brendan had mentioned there was one in the acrosses. In fact I had worked out 3d myself, I'd just forgotten. 8d I see the I, but still don't know if I've got the right answer. I'm not sure my answer means reservations. I need to lose an s and gain a t. In fact I had worked out 26ac. I'd just forgotten how I got it.
My FOI was 1ac closely followed by 4d, though at first I spelt the first word wrongly!
My LOI was 8d and I'm still not sure about it.
My CODs were 14d and 10d
I'm looking forward to watching Scrublands tonight. I read the book last year in my book group and we all thought it wonderful. I'm afraid the follow up wasn't so highly rated by us.
