A Forensic Expert's Guide to Identifying, Preventing, and Overcoming Infidelity in the Digital Age

Anatomy of Betrayal is a professional yet deeply human exploration of infidelity, suspicion, and the search for truth in the digital age. José A. Landa approaches relationship crises from a unique perspective: that of a forensic expert accustomed to evaluating credibility when words are no longer enough and doubt has become a source of psychological suffering.

Rather than treating betrayal as a simple moral issue, the book examines it as a relational, behavioral, and psychophysiological phenomenon. Through a direct, technical, and accessible narrative, the author explores the explicit and implicit agreements that sustain intimate relationships, as well as the emerging forms of physical, emotional, digital, and financial infidelity. Readers will gain insight into concepts such as gaslighting, pathological jealousy, betrayal trauma, and the obsessive need for certainty that often arises when trust is shattered.

Far removed from sensationalism, the book explains how polygraph testing can serve as a tool for verification, containment, and clarity when applied under rigorous ethical and professional standards. It demystifies the so-called “lie detector,” highlights the critical importance of precise question formulation, and presents the examiner’s role as that of a neutral specialist operating within one of the most emotionally complex areas of credibility assessment.

More than a book about infidelity, Anatomy of Betrayal is a practical guide to understanding the damage caused by intimate deception and the difficult decisions that follow its discovery: repair, radical transparency, reconstruction, or dignified closure. Intended for couples in crisis, therapists, attorneys, mediators, and forensic professionals, this work provides a clear and methodical roadmap for identifying, confronting, and overcoming betrayal through evidence, structure, and emotional clarity.
