Mystery novels appeal because they can be a form of mental exercise. Reading them requires you to pay attention to details, make connections, and think logically. It's like solving a puzzle, and when you finally figure out the solution, it gives you a great sense of satisfaction.
Mystery novels are appealing because they keep you in suspense. You are constantly trying to figure out 'whodunit' along with the detective in the story.
They often have complex characters. For instance, in many mystery novels, the villain might seem like an ordinary person at first, but as the story unfolds, you discover their true motives and personalities. This adds depth to the reading experience. Also, the settings in mystery novels can be very alluring. Whether it's a spooky old mansion or a gritty urban alleyway, the setting sets the mood for the mystery and draws the reader in. It makes you feel like you are part of the investigation, trying to solve the mystery right there with the characters.
