It's beaten me this time! I am stuck on 6 down - "More promising when top's off tree", 23 ac "dispatch parcel to a queen" and 21 down "sound way to source".
By the way, it does help if you give the number of letters in the clue, and any letters you have. I got these answers from memory, because I've already done this crossword.
I had "osier" for the 6 down answer, "more promising when top's off tree", but couldn't rationalise it, except osier was the only tree which fitted!
Another thread here - I am about to change my e-mail address, as changing to a new isp. How do I change it so I still have access to this site (which I now cannot do without ...!)?
