As The Map Room blog points out, an article by Axel Bax et al. (Cornell University) in Computational Humanities Research 2025 that takes a deep dive into the presence of maps in fiction indicates—probably to no surprise of mystery fans—that "small-scale maps often were in the detective/mystery genre."
