Why does JK Rowling use a pen name?

The series is based on JK Rowling’s fourth book in her crime fiction series penned under pseudonym Robert Galbraith.

Also called Lethal White, the book was published in September 2018.

The fifth novel in the series, Troubled Blood, is set to be published on September 15, 2020.

Writing on her alter-ego’s official website, Rowling stated that her original intention for writing as Robert Galbraith was for the books to be judged on their own merit, and to establish Galbraith as a well-regarded name in crime in its own right.

She got the pen name from her political hero Robert F Kennedy and her childhood fantasy name ‘Ella Galbraith’.
