The ending of a mystery story usually reveals who committed the crime or caused the mysterious event, and why.

What’s The Appeal of Mystery Stories?

Mystery stories are a popular genre of fiction because they provide readers with an opportunity to use their own problem-solving skills. In addition to the suspense, twists, and turns that keep readers interested, mystery stories often require careful attention and analysis on the part of the reader in order to get to the bottom of the mystery. This provides a unique challenge and reward for the readers who are able to solve the puzzle.

Mystery stories also allow the reader to explore a world in which they can never be sure of what’s going to happen next. This often provides an exciting escape from reality, as readers become engrossed in their pursuit of the answers. Mystery stories frequently use complex plot lines and interesting characters, which make them particularly engaging to read.
