Oh it's the dog's kneecaps, it really is. 620 words in 20 minutes. If I could do that 3 times a day I might get this novel finished AND have a tidy house. I'd have to turn off the 'net though.
This is what I'm writing about at the moment - or rather a bit of it a little further along. Makes you want to get your mallet out and have a tap, doesn't it?
