The term "whydunit" refers to a mystery genre that focuses on the motive behind a crime rather than the actual crime itself. Synonyms for this genre include psychological thriller, suspenseful drama, or character-driven mystery. These types of stories involve a deep exploration of the inner workings of the human mind and the reasons why someone would commit a heinous act such as murder. The whydunit genre is often more about the characters than the plot, as the focus is on their emotional and psychological state. Other related genres include crime drama, police procedural, and legal thriller, but the whydunit genre stands out with its emphasis on the psychological aspect of the story.
