J.K. Rowling pens new book under a pseudonym

J.K. Rowling has written a crime novel called 'The Cuckoo's Calling' under the pseudonym Robert Galbraith, it has been revealed.

Rowling told the Sunday Times of London that she had hoped to keep this secret a little longer because writing under a pseudonym has been a liberating experience, the Daily Telegraph reported.

According to the Huffington Post, the novel was published in April by Sphere in the UK - the same imprint at Little, Brown as her first fiction novel after Harry Potter, The Casual Vacancy.

Set in London, it features a one-legged private detective called Cormoran Strike, who is hired to investigate the death of a supermodel called Lula Landry.
