When the Amazon Books editors set out to compile a list of 100 Mysteries & Thrillers to Read in a Lifetime, we knew we were taking on a difficult task. The category contains several subgenres, and we made it our goal to include something from each one. Here you'll find literature and pulp. You'll find police procedurals, international thrillers, and everything in between. You'll even find a handful of books for young readers. During the process, some of us renewed our pleasure in reading a good mystery. Others rediscovered the joy of the thriller. But whether we were reading these titles for the first time or revisiting them – and despite the lobbying and occasional arguing that went along with our meetings – we had a blast. We hope you'll find a book to keep you reading long into the night.
