The Detective Markham Mystery series by Catherine Moloney is one of the more prolific entries in the crime fiction genre, running to 26 books between 2018 and 2024. Catherine Moloney published at a fast clip — four books in 2019, four in 2020, and four more in 2021 — before Crime in the Tower closed out the list in 2024. The series takes Detective Markham through a wide variety of settings, with cases set in a choir, a school, a garden, a hospital, a ballet, a gallery, a ballroom, a book club, a college, a kitchen, a spa, a crypt, and more.
The first entry, A Walking Shadow / Crime in the Choir, appeared in 2018 and set the template the series would follow across all 26 books. Reading in publication order is recommended, since characters and threads carry through the long run. The most recent entry, Crime in the Tower, was published in 2024.
