In the mood for a real head-scratcher of a mystery? There is, of course, always Cain’s Jawbone — the infamously complex novel that, almost a century after its publication, only a handful of people have solved. Of all the things that can be said about Cain’s Jawbone, you can’t call its intricate plot or the painstaking process of investigating it for yourself boring.
But if you’re a newcomer to puzzle mysteries, starting with Cain’s Jawbone can be asking for disappointment. It’s not for lack of trying, after all, that so few have cracked it. You’ll want to work yourself up to it by reading plenty of satisfying, yet puzzling mysteries and building your deductive reasoning skills.
These 10 mysteries are centered around particularly clever and puzzling plots. Some are self-aware of their difficulty and the genre itself, offering a metafictional narrative or themed premise that can be entertaining for more seasoned mystery fans. New mystery genre readers, too, will enjoy honing their armchair sleuthing skills with each book.
