For readers looking to protect themselves from those looking to take advantage, an essential guide on “deception detection,” written by a renowned trial consultant, behavioral analyst, and body language expert.

Having consulted on some of the most high-profile cases of the last two decades—including Michael Jackson, Jeffrey Epstein, and Elizabeth Holmes—Susan Constantine has met her fair share of scammers, con artists, predators, and murderers. For all their differences, Susan has long noticed that they all share one thing in common: their sole intention is to take something from you to benefit themselves. They can be likable, approachable, charismatic, charming, and helpful—and you need to learn how to protect yourself from them. Susan started teaching her methods about “how to spot a liar” over twenty years ago, realizing the need for attorneys to become more proficient in spotting lies in the courtroom, as well as vetting clients and witnesses.

In How to Spot a Liar in 7 Seconds or Less, Susan shares lessons from her course with the general public for the first time, showing readers how to not just spot liars, but how to outsmart them. Using her proven techniques, readers learn how to discern the incongruence between a person’s facial expressions, body language, spoken/written words, and demeanor, heightening their awareness to key signs of deception—and all within just seven seconds. This book empowers readers to take control over the social settings they find themselves in—and protect themselves and their loved ones from harm.

Eye-opening and utterly engaging, How to Spot a Liar in 7 Seconds or Less is essential for anyone who wants to learn what makes people tick, what motivates liars to bend the truth, and how to defend themselves against them.
