For her latest book, however, Rowling went the opposite route by publishing a 450-page crime novel called The Cuckoo's Calling under the pseudonym Robert Galbraith!
"I had hoped to keep this secret a little longer because being Robert Galbraith has been such a liberating experience," Rowling said when approached. "It has been wonderful to publish without hype or expectation and pure pleasure to get feedback under a different name."
