#1 New York Times bestselling author C. J. Box’s Treasure State finds Cassie Dewell in Montana on the trail of a con man. This audiobook is read by Christina Delaine. I love listening to audiobooks across many genres, but one of my favorite types of genres to listen to? Mysteries, obviously. Mysteries just lend themselves so well to the audiobook form. The right narration ups the sense of suspense in the story and creates the perfect atmosphere for surprising twists and turns. Sometimes mystery audiobooks pull out a full cast of narrators to really bring the characters to life. Sometimes one dynamic narrator is all you need to create a story that will have you glued to your earbuds. Quite a few of these books are newer titles, and some are older mysteries than are just impossible to get out of your head. Some of these stories are dark and creepy. Some are super cozy. Although each of the books on this list is different, the twenty audio mysteries on this list are all here for similar reasons: propulsive storylines, surprising twists and turns, unforgettable characters, and compelling narrators. If all of that sounds appealing to you, then check out these twenty must-listen audio mysteries. Twenty audiobooks not enough to get you through?
