I too am stuck with a complete grid and the 4 link words identified by krauton. I'm trying to find the dedicatees' surnames from the letters removed from the down clues. I have 10 of these - can anyone please confirm that this is correct - or have I missed some?
I took 23d as a partially &Lit clue. 'walls' is a containment indicator, but the first 5 words are also the def.
'ball' (1) in 'to hurl at' (4) + 'one' (1)
