The Sunday Times newspaper quoted Ian Rankin, a fellow author and neighbor of Rowling's, as saying the creator of the "Harry Potter" books is turning to crime fiction.

"My wife spotted her writing her Edinburgh criminal detective novel," the newspaper, which was available late Saturday, quoted Rankin as telling a reporter at an Edinburgh literary festival.

In an interview with The Associated Press last month, Rowling said she believed she was unlikely to repeat the success of the Potter series, but confirmed she had plans to work on new books.

"I'll do exactly what I did with Harry — I'll write what I really want to write," Rowling said.
