Why Do People Lie? By Pradeep Roka Lies leave traces. The body always knows. Dr. Aarav Sen is a master at reading them - the quickened pulse, the fleeting microexpression, the subtle shift in breathing. As a behavioral analyst, he's spent years uncovering the truths people work hardest to hide. When a high-profile corruption case pulls him into the orbit of Kabir Kapoor - a charming politician with too-perfect answers - Aarav finds himself navigating a dangerous game of deceit. But the deeper he goes, the murkier the lines between truth and lies become. A mysterious journalist, an old flame with unfinished business, and a trail of evidence that points in unexpected directions force Aarav to confront not just the lies around him... but the ones within himself. From rain-soaked streets of Delhi to glittering gala halls where masks are worn in more ways than one, Why Do People Lie? is a gripping psychological drama that blends suspense, human emotion, and real science behind deception detection. In this book you will discover: The subtle cues that betray a lie - drawn from real behavioral science. A tense, twist-filled investigation where no one is entirely innocent. A powerful reflection on why people hide the truth, and what it costs them. Perfect for readers of psychological thrillers, crime dramas, and anyone fascinated by the secrets we keep.
