Normal Till They're Not traces the long, unsettling history of serial murder, from ancient courts and forgotten roads to suburban homes, hospital wards, cults, criminal networks, and the killers who learned to hide behind familiar faces.

Moving beyond the usual roll call of infamous names, Van Rothrock examines the myths that have shaped our understanding of these crimes. Were serial killers really lone predators? Were they criminal masterminds, or did institutions, influence, indifference, and human error help them remain unseen? Drawing together historical cases, criminal typologies, disputed investigations, female offenders, hidden victim counts, and the disturbing failures that allowed violence to continue, this book follows the record wherever it leads.

The result is a dark, provocative journey through the stories we remember, the victims history overlooked, and the questions official accounts did not always answer. It is not only an examination of monsters. It is an examination of the systems, assumptions, and silences that gave them room to hunt.

Because the most dangerous killer is not always the stranger in the shadows. Sometimes it is the person everyone thought they knew.
