J. K. Rowling, author of the mega-bestselling Harry Potter books, is writing a detective novel, according to the Sunday Times of London. AP reports:

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.

A mystery series selling in the hundreds of millions, as the Harry Potter series did, would certainly be good for the genre’s overall popularity—but is exceedingly unlikely. However, Rowling’s ability to bring imagination and some interesting ideas to genre fiction has been fully proven, and her effort could indeed be refreshing for a form of fiction that has become rather dreary in recent years.
