Fans of the Harry Potter series tend to hang on author JK Rowling’s every word. Through her very popular Twitter account, the author shares much of herself with fans (while also shutting down trolls on the reg), and often gives out little tidbits of HP information (like her huge Fantastic Beasts 2 hint). Now, the brain behind everyone’s favorite boy wizard is actually begging people not to buy a story she wrote, and for good reason.

The story, recently auctioned to support a writers’ charity, was stolen from its new owner’s home in late April along with several items of jewelry. Written on a single six by eight inch postcard, it is a short prequel to the events from the Harry Potter series.

With no word on the rest of the investigation, both Rowling and the police department are asking for fans of the author to help track down the priceless work. As private Constable Paul Jauncy said, “The only people who will buy this unique piece are true Harry Potter fans. We are appealing to anyone who sees, or is offered this item for sale, to contact police.”

Here’s to hoping the manuscript is returned to its rightful owner, and soon!
