A handwritten prequel to the Harry Potter novels which raised £25,000 for charity at an invitation-only auction will be used to raise further philanthropic funds, the buyer has said.

Speaking to Bloomberg News, Hira Digpal, president of Tokyo-based investment-banking consulting company Red-33, and the new owner of J.K. Rowling's handwritten 800-word short story, said he faxed a letter to Rowling's publisher asking for the author's co-operation to use the story in a way that would raise more money for charity. He declined to give Bloomberg details of the proposal.
 
Rowling's contribution was the last lot in the auction of works written on blank sheets of A5 card, called "What's Your Story?''  The 13 ‘storycards’ sold were written by illustrious authors, including Doris Lessing, Tom Stoppard, Sebastian Faulks, Richard Ford and Nick Hornby.

Waterstone’s, the bookseller, hosted the sale attended by 100 guests and the £47,150 raised in total will go to English PEN and Dyslexia Action.

All the ‘storycards’ were sold without reserves and buyers paid no auction-house fees.

Amazon.com Inc. paid a record £1.95m at auction in December for Rowling's handwritten volume “The Tales of Beedle the Bard'' at a Sotheby's charity sale in London.

J.K. Rowling’s philanthropy was featured in Philanthropy UK’s recently published Women & Philanthropy report.
