NEW YORK (AP) - Not many people read "The Cuckoo's Calling" before word leaked out over the weekend that author Robert Galbraith was, in fact, J.K. Rowling. But a handful who did managed to get a signed copy. And that could mean a lot of money. Rowling spokeswoman Nicky Stonehill told The Associated Press on Tuesday that Rowling, the "Harry Potter" author, signed a few copies of her detective novel as "Robert Galbraith." Bids for a first edition signed as Galbraith have topped $1,000 on eBay. Stonehill declined to comment on how any reader obtained a signed copy. "The Cuckoo's Calling" was published quietly in April. It is No. 1 on Amazon.com and publisher Little, Brown and Company has commissioned a new printing of 300,000 copies.
