6 elements of a mystery

1. Crime: In any mystery, crime must be included. Looking at mystery books or movies, detectives always try to solve unanswered problem, another word for "crime". A crime is an illegal action, as you can see in the picture, trying to shoot a person with a gun, which remains unanswered later and detectives come to solve what happened. The people who committed the crime can be punished by laws if they are caught.
2. Detective, inspector, sleuth and agent: To solve a crime, detective comes. In another word, detective is a person who tries to solve unanswered problems, or crime. One of the famous detectives is Sherlock Homes who has pipe in his mouth, magnifying glass and a hat.
3. Villain: Villain is a bad guy who committed the crime. Villain is also "wanted man". Detectives try to solve a crime as well as try to catch the villain to find out the villain's motive why he/she committed the crime.

4: Evidence: Detectives try to find evidences to catch the villain because evidence helps solving the crime. Evidence is a thing that can be touched like hair, fingerprint while clue is a thing that cannot be touched.5: Suspects: When detectives got enough evidences, they suspect people who done the crime which is suspects, with their evidences. Detectives examine the person or ask some questions. One of the suspects might be the villain or might not be the villain.6: Surprise ending: For me, I think surprise ending is really important. Surprise ending makes readers go flabbergasted. This keeps the book very interesting, fun, fascinates the readers and most importantly, makes people think in different, wide and various ways.
