“Susan takes us inside the minds of sociopaths and serial liars and teaches us exactly how to spot them. Protect yourselves. This is a must read!”

“Susan equips you with the skills to spot hidden predators… offering clear, actionable signs to help you detect threats and protect your loved ones.”

“In law enforcement, seconds count… Susan Constantine is giving you the playbook. This book should be on every investigator's desk!”

Every day, you interact with people who are not fully telling the truth — whether it is a colleague withholding information, a partner hiding something deeper, or a stranger with intentions you cannot quite place. The danger is not just that people lie. It is that they often do it convincingly.
In How to Spot a Liar in 7 Seconds or Less, renowned behavioral analyst and trial consultant Susan Constantine pulls back the curtain on deception — revealing how liars unknowingly expose themselves through subtle inconsistencies in their behavior. Drawing from over two decades of experience working on high-profile cases and training attorneys, law enforcement, and federal professionals, Susan teaches you how to detect these signals quickly, accurately, and with confidence.
This is not about guessing or relying on gut instinct. It is about learning how to observe what most people overlook — the disconnect between what someone says and what their body, face, tone, and demeanor reveals. Through real-world examples and science-backed techniques, you will begin to recognize patterns of deception within seconds — not after the damage is already done.
This book will help you:
Recognize deception within seconds so you stop missing the signs right in front of you
Make faster, more confident decisions about who to trust
Protect yourself from manipulation, scams, and hidden agendas
Understand the patterns and psychology behind why people lie
Develop a trained eye for behavior — not just words — so you can see what others miss

Susan Constantine is a leading authority on behavior intelligence, deception detection, and human behavior with over 20 years of experience. She has worked as a trial consultant on high-profile cases and trained attorneys, federal judges, law enforcement, and government agencies to accurately assess credibility and uncover the truth. A sought-after media expert, Susan has appeared on more than 3,500 national and international television, radio, and print outlets — including CNN, Fox News, Court TV, and Good Morning America — Using science-backed behavioral analysis and her proprietary 6-Second Behavioral Scan™, Susan helps leaders, attorneys, and organizations uncover hidden behavioral patterns, assess credibility, and make smarter decisions under pressure.

You have trusted your instincts throughout your life. But what if the signals you have been relying on are not the ones that matter most?
After more than two decades of studying human behavior and working alongside attorneys, law enforcement, and federal professionals, I have seen one thing over and over again: the truth is always there — people just do not know how to recognize it.
This book was written to change that.
I want to show you how to see what others miss. How to recognize deception before it costs you. And how to feel confident in your ability to read people in any situation.
Because when you understand behavior — not just words — you stop second-guessing. You stop overlooking red flags. And you start making decisions from a place of clarity, not uncertainty.
My goal is simple: to give you the tools to protect yourself, your family, and your future.
Once you see it, you cannot unsee it.
