Way back on December 15, 2020, I posted a Master List of the Best Mysteries, Crime Novels and Thrillers Lists of 2020 with a summary at the end, showing which titles had been mentioned most on those lists. Since then I have added at least 10 more lists to the Master List and so I am making this post to alert those who haven’t been regularly re-checking the prior post. The Master List now contains 50 “Best” Lists. You can scroll down on the home page or you can click here to see the newly revised Master List.
