Hi
I'm stuck on three, any help would be appreciated
8 across: Inform uncle, unsure about crossword compiler (4,2)
_ _ _ E _ N
1 down: A botched jobgoing uphill, deer shelters you, thank God (6)
_ _ _ D _ E
and finally
13 across: Not a gentleman long, I'll help ruin Twain's long walk (6)
C _ D _ I _
8a Clue in - anag 'uncle' + I (the compiler)
1d Kludge - 'elk' (deer) (up, round) u + dg (Dei gratia - "by the grace of god")
13a Cad-die - "golf - a long walk spoiled"
