JK Rowling Revealed as 'Robert Galbraith,' Author of Debut Mystery Novel 'The Cuckoo's Calling'

Harry Potter author JK Rowling has been revealed as the author of a "debut" mystery novel The Cuckoo's Calling, according to a statement the writer gave to The Sunday Times of London.

The book was written under the pseudonym Robert Galbraith. He was supposed to have been a former British soldier who left the military in 2003 and worked as a civilian in the security industry.

Following an anonymous tip to the paper, Rowling fessed up that she was, indeed, Galbraith. "I had hoped to keep this secret a little longer, because being Robert Galbraith has been such a liberating experience. It has been wonderful to publish without hype or expectation, and pure pleasure to get feedback under a different name," she wrote in a statement.

According to Entertainment Weekly, the book received stellar reviews but barely made a mark in sales in America or Rowling's homeland of England.

The Cuckoo's Calling is about Coroman Strike, an Afghanistan veteran who lost his leg in a land mine accident. He begins the novel as a down-and-out private investigator whose sister, a supermodel, has fallen to her death. It was ruled as suicide, but Strike refuses to believe that is the case. He investigates her death and gets pulled into the world of the rich and famous.

Now that Rowling has been revealed as the true author of The Cuckoo's Calling, sales of the mystery novel are expected to skyrocket.
