You may have heard that the author of recent "debut" private eye novel The Cuckoo's Calling was actually beloved children's author J.K. Rowling under the pseudonym Robert Galbraith. As a P.I. fiction fan, I've been hesitant to jump on the Harry Potter bandwagon but am intrigued to compare Rowling's work in the different genres.
Pseudonyms are a time-honored way for authors to branch out. I wouldn't hesitate to use one, but I'll always be grateful to have broken into print under my own name, indeed Gerald So.
