A wide array of films fit under the umbrella of murder mystery. In our list, we’re counting missing people, as those movies are pretty similar to murder mysteries, with investigations, multiple suspects, and twist endings. They have more hopeful endings when characters can find the missing person alive, but the journey to the end is still fraught with nail-biting thrills and mystery. Fans of Gone Girl or a A Simple Favor can feel vindicated; they’re both worthy additions to the list, even without a dead body for investigators to ponder over.
