Read "Moonflower Murders"

If you’ve got an Amazon Prime account you can read “Moonflower Murders” by Anthony Horowitz for free. And you should. It’s the second book in a series.

You’ll have to buy the first one (and you probably will). Both are a good read in an Agatha Christie kind of way. I don’t want to spoil your experience by telling you what happens but if you like traditional murder mysteries I think you’ll rather like it.
