As an experiment for a class I'm planning for fall, I created a discussion forum on Ning called The Dripping Dagger: a Mystery Book Club
Modeled after the Mystery Group I attend each month, it is a one book a month discussion.
The forum is public so anyone can join in the discussion.
The May selection is Nobody Lives Forever by Edna Buchanan. This happens to be the selection for our real world group as well. It came out in 1990 and it is a tough book to find. Consider locating a copy to read to be your own first bit of detection!
