J. K. Rowling announces Second Novel written by Robert Galbraith, her Pseudonym and Alter Ego, euphemisms for Alternate Personality

When the author of the Harry Potter novels published The Cuckoo’s Calling under the pseudonym Robert Galbraith, but was found out, she explained that she had wanted to see how the book would do without the benefit of her fame. So why, now that everyone knows Robert Galbraith is her pseudonym, is she continuing to use it for a second novel?

Regarding the origin of the name, she explains that “When I was a child, I really wanted to be called Ella Galbraith, I’ve no idea why…the name had a fascination for me.”

Is Robert Galbraith a pseudonym for an alternate personality, Ella Galbraith? Is he Ella Galbraith’s brother? Does Rowling know?
