An untitled Harry Potter prequel handwritten on a postcard by JK Rowling has been stolen in a burglary in Birmingham.
The "extremely valuable" 800-word work was penned on both sides of the A5 card for a charity auction nine years ago and sold for £25,000 at Sotheby&apos;s.
The manuscript and a quantity of jewellery were stolen from a property in Howard Road, Kings Heath, during a break-in between April 13 and 24.
West Midlands Police have issued a plea for information in the hope that "the appeal goes far and wide among Harry Potter fans throughout the world".
The prequel was among several works donated by authors, including Sebastian Faulks and Doris Lessing, to an auction held in 2008 to raise funds for English PEN, which promotes understanding through literature, and Dyslexia Action.
