It’s hard to believe we are already more than halfway through 2021! This year has already delivered truly outstanding crime, mystery, thriller, and suspense books for us to devour, and today I wanted to round up a list of my favorite crime books published in the first half of the year! Whether you’re in the market for a chilling suspense story, a clever locked room mystery, or an edge-of-your-seat psychological thriller, this list has a little something for you. From new releases by returning favorites (Riley Sager, C.J. Tudor, Ragnar Jonasson, and more!) to thrilling debuts and new-to-me authors, 2021 has given me some absolutely incredible crime books to sink my teeth into - and I hope that this list will help you find a new favorite crime book or two for yourself, too! As you can imagine it was very difficult to narrow this list down.

The books included on this list were published from January 1, 2021 through July 6, 2021; stay tuned, because I’ll be rounding up a list of my favorite crime books from the second half of 2021 - plus a definitive list of my favorite crime books of the whole year - when 2021 comes to a close.
