I'm sure you all have seen the news this week saying that Rowling is starting work on a mystery novel.
One thing I will say is that in order to write a compelling mystery novel, an author must be skilled at creative plot twists and convincing red herrings. Rowling's proven her skill with red herrings and plot twists with the Potter books. She's also very good at setting the scene and mood without it getting too wordy So I do think she's very capable of writing a good mystery novel. Plus, when it comes to mystery and detective novels, I've always preferred British over American. Sherlock Holmes vs. Phillip Marlowe? I'll pick Holmes every time.
On the other hand, people may probably be disappointed because it's not Harry Potter.
I'm curious whether Rowling is going to gear the mystery novel more towards adult readers. It'd be nice if she did, because she's a skilled writer, but many adults won't read Potter because of the whole "it's for kids" stigma. Plus, in terms of mystery novels for the teen and tween crowd, not even the almighty Rowling can compete with the likes of Nancy Drew and The Hardy Boys in my opinion.
I'm curious to see how it turns out.
