The famous Harry Potter author has been spotted in Scottish cafes working on a new novel. This time, Rowling is writing crime fiction – a detective novel. J. K. Rowling wrote Harry Potter in similar cafes, back when she was still struggling to make ends meet and get the bills paid. Today, she’s richer than Queen Elizabeth. Harry Potter books have sold more than 335 million copies worldwide and spawned a slew of successful movies. Last month, Rowling re-affirmed her plans to leave the Harry Potter saga as is, and continue with new, different stories. Rowling’s literary agent has yet to confirm plans for her newest book.
