J.K. Rowling Published 'The Cuckoo's Calling' Under A "Liberating" Pseudonym

J.K. Rowling, author of the hugely popular Harry Potter series, admitted she had published a detective novel under the pseudonym 'Robert Galbraith'. Her announcement was made on Sunday 14th July after a newspaper followed up on a hunch that the 'two' authors shared very similar writing styles. The novel, entitled The Cuckoo's Calling, was published in April of this year. Despite receiving critical acclaim the novel sold less than 500 copies.

Since her unveiling as the author, The Cuckoo's Calling sale figures have shot up dramatically with its position in the Amazon sellers list having moved up thousands (from 5076th to 1st).

The 47-year-old shot to fame after her Harry Potter books became world renowned and much loved best-sellers. They appear on numerous lists of need-to-read literary works and are the best-selling series of books in history.

The books were adapted into eight films which helped launch the careers of Daniel Radcliffe, who played Harry Potter, and Emma Watson and Rupert Grint (Hermione and Ron). In addition to films Rowling's concept has spawned a vast franchise including Harry Potter games, tourist attractions, clothing, Lego, figurines and board games.
