J.K. Rowling says her crime-writing alter ego Robert Galbraith had respectable sales and two TV adaptation offers before he was exposed as a pseudonym for the ‘‘Harry Potter’’ novelist.
Rowling said ‘‘Robert was doing rather better than we had expected him to,’’ selling 8,500 copies in print, audiobook, and e-book formats of thriller ‘‘The Cuckoo’s Calling,’’ which was published in April.
The author was allegedly a former military man, but a newspaper revealed this month that Rowling had written the book under a pseudonym.
