Oops, haven't really read the supernatural one so I kinda forgotten about what I've read before...
If you're looking for mystery though, I would suggest you read Agatha Christie's book. They're old, but I still love them. There's a couple movies and TV series plus radio play, so you can just pick one of the media to try it out.
My most recommendation is and then there were none (old name is ten little niggers/imdians), crooked house, the murder on orient express, and the murder of Roger Ackroyd.
There is an old movie for the and then there were none and a 2017 movie for the murder on orient express. Another movie titled the murder on nile is supposed to out in 2020. (I haven't watch the movie yet)
There's also lovely bones. I just bought the book yesterday and haven't read it, bit I really like the movie. It's both supernatural and murder mystery.
