So I was on the internet the other day trying to find mystery books to read... here are some that I found out were pretty popular on www.goodreads.com:
The Girl With the Dragon Tattoo (Millennium, #1)
The Lovely Bones (Mass Market Paperback)
The Body in the Library (Miss Marple, #3)
The Woman in White (Paperback)
The Complete Sherlock Holmes (Paperback)
Arthur Conan Doyle
Just to name a few! I did not see these series on Goodreads, but I didn't go through the long list; I would totally recommend the 'Dead is...' series!
