Behind ordinary doors, some of the darkest crimes in modern history were hidden from the world.

Serial Kills Horrors examines ten real cases where homes, basements, crawl spaces, bunkers, and hidden rooms became scenes of captivity, torture, murder, and unimaginable fear. From the Philadelphia basement of Gary Heidnik to the Cleveland captivity case of Ariel Castro, from Josef Fritzl’s hidden cellar in Austria to the nightmare crimes of Fred and Rose West, this book takes listeners inside the cases that shocked investigators, horrified the public, and exposed how evil can hide in plain sight.

Written in a gripping, accessible true crime style, this book explores the crimes, the victims, the investigations, the warning signs, and the lasting impact of each case.

Inside, you’ll listen about: Gary Heidnik and the Philadelphia basement captivity case Ariel Castro and the Cleveland kidnappings Josef Fritzl and the Austrian hidden basement case Fred and Rose West and the Gloucester house murders Robert Berdella and the Kansas City torture murders Leonard Lake and Charles Ng’s bunker and cabin crimes David Parker Ray, known as the “Toy Box Killer” Cameron Hooker and the captivity of Colleen Stan John Wayne Gacy and the crawl space burial murders Dean Corll and the Houston torture murder case.
