Well personally I'm horrified to read the above two comments. In answer to the first, you should know that he is Reverend John Galbraith Graham. He is THE top compiler of the Guardian and his puzzles are certainly not completed with the use of Google and Wikipedia.
From what you've said it's quite clear that you rarely, if ever, manage to complete one!
I take great exception to these remarks.
Have either of you ever completed one of his Perimetricals?
As for Kev, if you ALWAYS finish them then you're a clever git.
And a lucky one!
In all my years of using the internet I have never felt compelled to reply to something which is quite obviously twaddle - I usually treat it with the contempt it deserves.
Except in this case.
