Police are investigating the alleged theft of a copy of Grey (Arrow), the new novel in the Fifty Shades of Grey series by EL James.
The copy of the novel, due to be released next week, was reportedly discovered to be missing yesterday (2nd June).
Penguin Random House said it could not comment due to an ongoing police investigation, and added: "Grey will be published on 18th June - Christian Grey’s birthday - as planned."
It is not known where the copy has been stolen from.
Grey tells the story of Fifty Shades of Grey from the point of view of Christian Grey.
James said she wrote the novel after multiple requests from fans.
She said: “Christian is a complex character and readers have always been fascinated by his desires and motivations, and his troubled past. Also, as anyone who has ever been in a relationship knows, there are two sides to every story.”
Grey will be published in the UK as a paperback original and as an e-book by Arrow, an imprint of Cornerstone.
In 2003, copies of J K Rowling’s Harry Potter and the Order of the Phoenix were stolen from a trading estate.
In 2008 Stephanie Meyer’s partial draft of Midnight Sun, which told the story of Twilight from Edward Cullen’s point of view, was stolen and posted online.
Meyer posted the draft online for fans after the theft.
