Serial killers are a different breed of killer. They're people you know. People with families. They're often polite and cordial in public settings. They're often educated. And most times, they're just the guy-or girl-next door. But deep beneath the polite and innocent looking exterior, lays a deranged sociopath that kills habitually-and without a shred of mercy or remorse. Now, inside this book you'll gain a firsthand understanding of why serial killers do what they do.
