The upcoming mystery novel "The Silkworm" will be credited to J.K. Rowling's pseudonym Robert Galbraith, the book's publisher announced Monday. The Harry Potter scribe wrote 2013's "The Cuckoo's Calling" under the pen name, but her secret was revealed to the press without her permission. Rowling later explained she wanted to release a book without all of the fanfare and pressure that accompanied the publication of her wildly popular children's fantasy novels. Little, Brown and Co. said "The Silkworm" is to be published June 19 in the United Kingdom and June 24 in the United States. The Hollywood Reporter said the second installment in the series will again follow the adventures of private investigator Cormoran Strike.
