LONDON: JK Rowling is set to release her second novel under the pen name Robert Galbraith.  The ‘Harry Potter’ author wrote her first novel, ‘The Cuckoo’s Calling’, under the alias last year and she’s now working on a sequel to the bestselling crime novel, called ‘Silkworm’, which will be released later this year, according to publishers.  The 48-year-old writer had aimed to keep her crime writing venture a secret but her solicitor at the time revealed her pen name to the public and has since been fined and ordered to pay Rowling damages - which she donated to charity.  ‘Silkworm’ will be the author’s third book for adults.–XP
