USA Today: J.K. Rowling wrote "The Cuckoo's Calling" under the pseudonym Robert Galbraith, who was purportedly an ex-military man.
"I hoped to keep this secret a little longer because being Robert Galbraith has been such a liberating experience," she said in a statement released by her publicist on Sunday. "It has been wonderful to publish without hype or expectation, and pure pleasure to get feedback from publishers and readers under a different name."
The Sunday Times claimed it was investigating "how a first-time author with a background in the army and the civilian security industry could write such an assured debut novel" when it connected the dots. The paper said clues included the fact that Rowling and Galbraith shared the same agent and editor, and that Little, Brown published Rowling's novel for adults, "The Casual Vacancy." It also said the book's style and subject matter resembled Rowling's work.
