Calendar of Crime Challenge 2020

This reading challenge is hosted by Bev at My Reader's Block. It will allow mystery readers to include any mystery regardless of publication date. If it falls in a mystery category (crime fiction/detective novel/police procedural/suspense/thriller/spy & espionage/hard-boiled/cozy etc.), then it counts and it does not matter if it was published in 1892 or 2019.
The Challenge runs from January 1, 2020 to December 31, 2020
