I need suggestions for mysteries for my bookclub.  No cozies, we're kind of serious readers.  Any ideas?

How about the Millenium trilogy (The Girl with the Dragon Tattoo, played with fire, kicked the hornet's nest) by Stieg Larsson?

There's some room for discussion about corruption, journalistic ethics, etc.

Not to mention about Stieg himself -- http://www.nytimes.com/2010/05/23/magazine/23Larsson-t.html

I recommend some of Thomas H. Cook's mysteries.  They are a little different.  His Chatham School Affair won an Edgar.  Master of the Delta is another good one of his.

Shadow of the Wind by Carlos Ruiz Zafon.  One of my favorite books ever, it's got mystery mixed in with a haunting love story all taking place in a beautiful setting, Barcelona.  It's really great writing, and the story is mesmerizing. 

Also has one of my favorite first lines in a book ever

"I still remember the day my father took me to the Cemetery of Forgotten Books for the first time."

I was sucked in from that very first line.

I really enjoyed all of the books mentioned above.  Chatham School Affair was a real standout  for me though.

Giles Blunt has a series set in Canada that's very good, and of course there's Julia Spencer-Flemings Russ Van Alstyne series as well.  I found both to be more thoughtful than action oriented.

If you like historical mysteries, Ariana Franklin has a series set in the Middle Ages with a female protagonist who works as essentially a forensic examiner.

For a really dark mystery, Cody McFadyen's Smoky Barrett series is great too - but may be too disturbing for some.

And of course - if you do want more of an "action" mystery, there's Lee Child's Jack Reacher series.

I think COMPANY OF LIARS by Karen Maitland would be a wonderful read for a book club!  It is a historcal mystery.  It takes place in England during the Black Plague (1348.)  The story is about 9 desperate strangers that are brought together by chance. None are what they seem. Their stories are filled with myth, magic and superstition.....I loved it!  A lot to talk about!

The book is 465 pages. If you pick this book,  you may want to break it up into 2 parts.

Thank you all for some great suggestions.  Will look into them.
