Hi Chris
Well much to my surprise I've finished. Thanks to the hints here. I tried googling 17 and Titan and got nowhere, but checked out some of the poems and found the line. Not one of the poems I have ever come across, perhaps because I'm a vegetarian!
Anyway, getting 8/24 gave me lots of crossers and together with the hints was a great help.
Having said that there remain a number I can't fully parse: e.g 3d, 10ac, 21/7 and 9d. I know they are right because they match the definition.
My FOI was 17ac closely followed by 4d. (Well done Geeker for getting 4d). My LOI was 6d and 15ac, though the latter was obvious, 6d less so.
I was very sorry that 1d wasn't Ursine Baboon, but there was no "s" in the anagram so it was not to be.
I usually like Paul, but I can't say I enjoyed this one. So no CODs
Chris, I read lots of John Buchan from the library at Imperial College when I did my M.Sc. I also read lots of out-of-print Wilkie Collins from there.
