I don't think the next issue is out yet.
There is a poster on Answerbank called Maurice, I recall, who does this crossword and he has probably solved this one, so let's hope he sees your question
Lomax, if you read the preamble to the crossword it says
"The wordplay in each of the remaining clues generates the answer to be entered in the grid plus an additional letter"
Have you a Chambers dictionary Lomax?
It's very helpful for this type of crossword - in there the definition of vivisect (in addition to cutting surgically) is "merciless and minute examination or criticism" so no stretch.
I do have a Chambers somewhere but mostly use a "medium sized" Oxford. I've always thought that Chambers was too large because half the words were Scottish! Prejudice eh?
