If you have school-age children then the chances are you will have come across this little fella. And If you tell me that you haven't, then you're a liar. The little buggers are everywhere, whilst advice on how to deal with them is both erratic and often downright eccentric - put your child's head in a bucket of vinegar anyone?
Help, however, is at hand.
Justine, the Crow of this very parish, and her co-author Richard 'Bugman' Jones have been hard at work these past many months at what will surely come to be recognised as the vade mecum par excellence of head louse wrangling. I shit you not.
The book is published by A and C Black on May 15th and costs £4.99.
