A HIGHWORTH charity shop manager had a lucky find after being hit by a bolt of Hogwarts wizardry.

While picking through a mountain of unwanted books at the new Action for Children in Conflict shop, manager Therese Richards chanced upon three rare first edition Harry Potter books.

One of the books a hardback copy of Harry Potter and the Goblet of Fire - is worth around £100 because minor changes were made in later editions.

A tutor at Hogwarts, where boy wizard Harry is schooled in magic, called Barty Crouch makes an appearance, but there are slight changes in later editions. Author JK Rowling also changed a scene in which the evil Lord Voldemort makes Harry's mother Lily emerge from the tip of his wand.

In later books, it is Harry's father who appears.

The other finds are a hardback copy of the Order of the Phoenix, worth around £40, and a paperback copy of the Prisoner of Azkaban, which is valued at £30.

Therese, a big Harry Potter fan, said: "We've definitely been hit by a bit of Hogwarts magic!

"We have had boxes and boxes of books delivered, and I check through them all because occasionally you find collectibles.

"I knew these were worth more because they were first editions.

"I found more about them on the internet. It's just a really great boost, and will help our fundraising."

Several rare Harry Potter books have come under the hammer at Old Town's Dominic Winter Book Auctions.

Last year, a set of four signed first editions went for around £25,000.

The charity shop, which is opening on Tuesday in Highworth market square, will raise money to help children growing up under the shadow of war.

The Highworth store will specialise in second-hand books, CDs and records, and the charity is now hoping to open more shops in Wiltshire.

Based in Oxfordshire, the organisation has supported children in war-torn areas of the globe, including Sierra Leone and Tanzania.

Anyone who wants to donate items to the shop, or volunteer to work there, should call Therese on 01793 861742.
