The Rap Sheet's "One Book Project: Underappreciated Crime, Mystery & Thriller Fiction"
This list was compiled by The Rap Sheet (http://therapsheet.blogspot.com/), a blog devoted to crime fiction. They asked over 100 "crime novelists, book critics, and bloggers…to choose the one crime/mystery/thriller novel that they thought had been most unjustly overlooked, criminally forgotten, or underappreciated over the years." To read their comments (and discover who chose which books) go here: http://therapsheet-onebook.blogspot.com/.
The list is alphabetical by title.
