Hello Jon - the unclued letters are all anagrams of soups (minestrone, broth, leek etc) - as per the quote "The soup is chaos"
Laura and I have sporadically posted EV queries and toalisi has just joined in. There isn't a way to search on the site (at lest not that I know!) Just look for a thread with EV in the name - and feel free to post one yourself if you want a clue and think any of us can help. I found ev 915 not too bad but I'm stuck on 23a)! Cheers
