Reading a lot of detective novels is helpful for logical reasoning because detective novels usually contain complicated plots and logical structures. Through reading novels, readers can understand the logical relationships and possibilities in various situations and thus improve their logical reasoning ability. Mystery novels often involve puzzles and clues that the reader needs to carefully analyze and think about to infer the truth. By reading a large number of detective novels, readers can train their logical thinking and reasoning skills to better understand and use these skills. However, it was important to note that reading mystery novels alone could not directly improve one's logical reasoning ability. To improve one's logical reasoning ability, one needed to practice thinking and reasoning in real life, constantly explore and try new problems and situations.
