It’s one of crime fiction’s oldest tropes, and one of its most perennially-appealing, too: a group of individuals find themselves locked in a hotel (or on an island, or in a house… you get the idea!), a murderer in their midst. Who among them is the killer? The locked room mystery is an unfailingly entertaining crime fiction subgenre. Clever plots, impossible solutions, red herrings a plenty—there is so much to love about books that fall into this category, and they’ve been a longtime favorite for me ever since I began reading Agatha Christie novels back in the day! With the recent popularity of locked room-style mysteries including THE GUEST LIST by Lucy Foley and THE SANATORIUM by Sarah Pearse, I’ve been receiving more requests than ever for a blog post dedicated to my personal favorite locked room mystery recommendations. Well, the day is finally here! I’m thrilled to share my list of Recommended Locked Room Mysteries with CBTB readers today. From Nordic mysteries to modern-day twists on the genre to classics and more, I hope that every reader will find a little something to catch their eye in today’s blog post.
