How much are 800 handwritten words worth? When they're in the form of an ersatz prequel to J.K. Rowling's Harry Potter series, nearly $50,000.

On Tuesday night at a London auction house, a bid of 25,000 pounds (or $48,855) claimed someone a two-sided page on which Rowling wrote a preface to the mega-hit series of books and movies. The auction's proceeds will benefit a dyslexia charity and the writer's organization PEN. Twelve other authors and illustrators, including Nobel winner Doris Lessing and novelist Nick Hornby, offered similar short-form items for auction.

Lest anyone hope that Rowling's charitible scribblings might lead to something bigger (and bound), it should be noted that the document's final 12 words were: "From the prequel I am not working on - but it was fun!" - Anna Dimond
