With true crime's popularity skyrocketing over the past few years, there are more nonfiction novels out there than ever, but these are the few that are truly scarier than fiction. While there's always been an interest in human nature and crime, mixing them together to form a true crime novel wasn't always the inclination. Fictional accounts of horror have long reigned supreme, but it seems true crime is finally having its big moment in the spotlight, and because of that there are more true crime novels being written today than ever before, following intense and terrifying cases to the end.

While there are always going to be fictional novels that are able to ratchet up the terrifying-scale, true crime gets under a reader's skin in a completely different way. Rather than scaring readers with what-ifs, true crime lays out actual events and makes it clear that the worst possible things can happen, and have. While they're not meant to terrify readers, the morbid curiosity surrounding true crime is what makes it such an in-demand genre. With writers leaning into modern conventions while they write about crimes of the past and present, true crime work has become even scarier than fiction.
