If you want to get a sense of the plot of the next Harry Potter book, it’ll only cost you $9500 or so. The latest installment of the wildly popular series by J.K. Rowling still has no official publication date, but Rowling has announced that she has prepared an index card with 93 ‘random words’ on it which hint at the plot, and that card will be auctioned next month at Sotheby’s in London. Seriously, an index card. Will be auctioned. At Sotheby’s.
