I am a great fan of the Daily Telegraph Cryptic crossword, and have been doing, or attempting to do this crossword, just about every day since I was a student at University.
I was introduced to it by my Grandmother many years ago, when stayed with her in Banbury.
"We" (and I use We, advisedly) used to do the crossword when we had breakfast, usually my Grandmother doing the crossword and explaining how things worked, whilst every now and then I would have a eureka moment. Anyway enough digression.
I found the following web site that specialises in helping people through the Telegraph Cryptic crossword in a way that is much more friendly than normal "specialist" cryptic sites.

For those of you who don't know Libellule, is french for Dragonfly.
