Captured in the 1930s before the words psychopath and pedophile were part of common vernacular, notorious serial killer Arnold Sodeman murdered four young girls with little thought of remorse. Without guilt, the evil serial killer strangled them to death with their own clothing and left their small bodies alone in the Australian brush, earning himself a chilling position in the annals of Australian crime.

In the Name of the Children gives an unflinching look at what it's like to fight a never-ending battle against an enemy far more insidious than terrorists: the predators, lurking amongst us, who seek to harm our children. During his 30-year career with the FBI, Jeff Rinek worked hundreds of investigations involving crimes against children: from stranger abduction to serial homicide to ritualized sexual abuse. Those who do this kind of work are required to plumb the depths of human depravity, to see things no one should ever have to see - and once seen can never forget.

During the early 1970s, more than three dozen teenage boys went missing from the working-class neighborhood of Houston Heights, in the south of Texas. The parents of a number of these boys received strange postcards from their sons, telling them that they were fine and that they had found jobs somewhere else in the state, anywhere from Dallas to Austin. Then, in August 1973, the Houston Police Department made a shocking discovery; something that would later become known as the Houston Mass Murders.

As investigators brought out the bagged remains of several dozen young men from a small Chicago ranch home and paraded them in front of a crowd of TV reporters and spectators, attention quickly turned to the owner of the house. John Gacy was an upstanding citizen, active in local politics and charities, famous for his themed parties and appearances as Pogo the Clown. But in the winter of 1978-79, he became known as one of many so-called “sex murderers” who had begun gaining notoriety in the random brutality of the 1970s.

Independence Day weekend, 1960: a young cop is murdered, shocking his close-knit community in Stamford, Connecticut. The killer remains at large, his identity still unknown. But on a beach not far away, a young Army doctor, on vacation from his post at a research lab in a maximum-security prison, faces a chilling realization. He knows who the shooter is. In fact, the man—a prisoner out on parole—had called him only days before. By helping his former charge and trainee, the doctor, a believer in second chances, may have inadvertently helped set the murder into motion.
