Was making steady progress through this but ground to a halt on the last two, both of which contribute to (c) which is looking like gibberish at the moment.
28d I can construct an answer from the wordplay but it doesn't match the definition so far as I can tell. Maybe a very gentle hint please.
31d I have an answer which matches the definition but I can't see the first part of the wordplay or the extra letter.
Until I can make sense of (c), I won't know how to approach the endgame. Thanks in advance
