Book Riot released details on titles that almost made their Best Mystery/Thriller Books of the Century So Far list. The selection process involved narrowing nominations to 50 standout works. All Access members receive the full list of contenders.
In a recent newsletter dated March 18, 2026, Book Riot provided behind-the-scenes insight into compiling their Best Mystery/Thriller Books of the Century So Far. The top 50 titles emerged from an initial list nearly twice as long, drawn from staff and contributor nominations. Editors verified publication dates within the century, removed duplicates, and debated extensively to finalize selections. Criteria included a book's impact, establishment or redefinition of subgenres, cultural splash, unexpected twists, and representation of diverse perspectives. The process resembled 'picking our favorite children,' as described in the post, with pride expressed in the outcome alongside recognition for strong contenders that fell short. Among the near-misses are A Master of Djinn by P. Djèlí Clark, Ninth House by Leigh Bardugo, The Dry by Jane Harper, and Truly Devious by Maureen Johnson, among dozens listed. This follows the list's release the previous week, part of an ongoing series after fantasy and romance installments. The newsletter also notes related genre news, such as Sherry Thomas’ The Librarians winning Best Mystery and Liann Zhang’s Julie Chan Is Dead Is Dead taking Best Thriller at the 2026 Libby Book Awards. Access to the bonus content requires an All Access subscription, offering exclusive features like the New Release Index.
