Ah, the pen name. For eons writers have been publishing titles under assumed names for one reason or another. The Brontë sisters used pseudonyms to avoid the prejudices female writers faced. Anne Rice used them to pen erotic novels, adding to their allure with exotic names (Anne Rampling, A. N. Roquelaure).
It turns out that Harry Potter scribe J.K. Rowling is the author behind “Robert Galbraith’s” The Cuckoo’s Calling. Amazon reviews are overwhelmingly positive, citing its “engrossing” twists and “complex and compelling” characters as a few of the highlights. “I had hoped to keep this secret a little longer because being Robert Galbraith has been such a liberating experience,” Rowling told press. “It has been wonderful to publish without hype or expectation and pure pleasure to get feedback under a different name.”
How did people figure it out? “Galbraith” and Rowling share the same publisher and editor.
