It must have been fun while it lasted, but now J.K. Rowling is back to square one. In a new statement on her website, she comes clean as the perpetrator of one of the best literary hoaxes in recent memory: in April, in collusion with her English editor, she published a detective story titled The Cuckoo’s Calling under the pseudonym Robert Galbraith. The novel was enthusiastically endorsed by such high-profile crime writers as Val McDermid, even though they had no idea who the real author was. It also got excellent reviews. Then last weekend the Sunday Times broke the story of her authorship, and Rowling quickly fessed up.
