When I was narrowing down the titles for this Top 20 list, I ended up with a shortlist of over 50 books.  So, after giving it some thought, I elected to divide the genre into Thrillers and Crime/Mystery.  The latter are more police, P.I., and organized crime-focused while the former cover pretty much everything else.  Of course, it’s a sliding scale and there may be some overlap.  Suffice it to say that between the two lists, you have 40 fantastic reads that should keep you busy well into 2021 or, if you’re me, end of summer.

Today, it’s My Top 20 Favorite Thrillers…
