CONVERSATIONS WITH KILLERS

Guilt is the only emotion you cannot fake.

Dr. Janna Cruz spent her career proving it. A forensic psychologist and former FBI profiler, she developed the Greg Guilt Inventory - named for her son - a 21-question assessment that measures guilt with unprecedented precision. Over two decades and hundreds of interviews, she has mapped the mechanics of conscience across three domains: what the guilty feel, what they do, and what they cannot stop thinking about.

In Conversations with Killers, Dr. Cruz presents the cases that defined her career. A serial manipulator who scores a perfect zero on the GGI. A suffocating mother whose love turned lethal. A settlement attorney who built a fortune on other people's tragedies. A hero uncle destroyed by the twin he couldn't save. A doctor whose fabricated research left a trail of bodies. Each interview is an unflinching look at how guilt shapes, transforms, and sometimes destroys the people who carry it - and what its absence reveals about those who can't.

Interspersed throughout are interviews with Cruz's colleagues - fellow psychologists who study guilt professionally but carry their own in ways that shape their practice. Their honesty reminds us that professional training doesn't exempt anyone from being human.

This is not a self-help book. There are no paths to forgiveness here. This is a book about learning to read the language of the one thing people cannot hide - and what it tells us about who they really are.
