I am a person who solves mysteries. I look for clues at crime scenes. I use a magnifying glass to see clues that people miss. I find fingerprints on murder weapons. I follow footprints to the villain's secret lair. I write my findings in my notebook. I work day and night to help people solve crimes. People come to me when something is stolen. I am not a policeman. I enjoy my job because I like solving crimes. My job rhymes with the word “positive”.
