As a senior myself, I love the rise of the senior sleuth that we've been seeing over the last ten years or so. Older amateur detectives bring decades of life experience, sharp instincts, and often a healthy disregard for what others expect of them. Best of all, these characters prove that solving crimes isn't just a young person's game. Here are some of the most entertaining four+ star senior sleuth mystery series to add to your reading list.
