As a frequently used theme in mystery novels and TV plays, perfect crime has been tried by countless predecessors. But if it is really a perfect crime, and it can't give the story an ending, so most occasions use "imperfect crime" that can finally reveal the truth.

In addition, there are works depicting perfect crimes in the form of auxiliary lines. Even in some cases, the motive and background of the prisoner aroused the sympathy of the role of detective, making it a perfect crime from the outside world. For example, Sherlock Holmes once spared at least four murderers.

Although the criminal plan itself is perfect, many stories have been exposed by unpredictable natural disasters, such as the once-in-a-decade typhoon, which brought back evidence that should have been buried deep under the sea. On the other hand, there are also cases where the footprints on the scene are completely erased because of the strong wind that cannot be blown, which occasionally leads to perfect crimes.

In addition, there are works that pay more attention to depicting prisoners' psychology than criminal means (how to escape police search, etc.) ). Because of conscience condemnation and anxiety, or suicidal impulse.

Criminologists and scientists say that a murder committed by a person who has nothing to do with the victim and has always obeyed the law may become a perfect crime without stealing anything or telling anyone afterwards. In addition, the crime may be committed in a noisy place, and it is more difficult to obtain evidence-screening evidence is like looking for a needle in a haystack.

As far as intentional homicide is concerned, disguising the scene as suicide is a common way to achieve a perfect crime. Other crimes are limited to never being discovered. In other words, even if it exists, it should not be recognized, otherwise it will not meet its definition.

As mentioned by some criminologists and mystery writers, it is obvious that the failure to find a perfect crime should not be due to the incompetence of investigators, but to the careful actions of prisoners. In other words, the focus should be on portraying the prisoner's ability to get rid of the pursuit, rather than trying to condemn the incompetence of the relevant institutions.

"Perfect Crime" in Film and Television Plays

On February 25th, 2009, three masked robbers broke into the second largest department store in Europe: Kaufhaus Des Westens in Berlin, Germany. They entered along the rope ladder, escaped all the alarms and stole millions of euros worth of jewelry. But they made a fatal mistake: they left a glove at the scene.
