I do send it in and have won twice. The first time, some 30 plus years ago I got a £10 book voucher, which was worth something then. Four years ago I got two books, one of which was Guardian Style, which I enjoy dipping into. The second one was dull. They changed it to Secrets of the Setters, which I hoped to win. I see it's changed again now so I might save the postage. I wish The Guardian would tell us how many entries they get.
On both occasions when I won, I did finish all by myself. The latter occasion was an Auracaria alphabetical. I won't send in one for which I have had some help.
Now back to the crossword, which I'm finding hard this week. I'm blaming it on my Dublin cold. Perhaps some lemsip will help?
