Limited edition signed short story by Ian Rankin - some still available

Ian Rankin wrote a short story which was available at the Edinburgh Festival this year, for a donation to the charity "SNIP".  1,000 copies were made and all were signed.  I see from his site that there are still some left.  Here's the link:

A minimum donation of £5 is sought.  The charity is the "Special Needs Information Point", based in Edinburgh, which "provides advice and information on services available to children with special needs and their carers".
