Crime fiction provides unique psychological impacts and enables readers to become mediated witnesses through identifying with eyewitnesses to a crime. Readers speak of crime fiction as a mode of escapism to cope with other aspects of their lives. Crime fiction provides distraction from readers’ personal lives through a strong narrative at a comfortable distance. Forensic crime novels have been referred to as "distraction therapy", proposing that crime fiction can improve mental health and be considered as a form of treatment to prevent depression.
