There are conversations that seem flawless: the words fit, the tone is perfect, they hold your gaze... and yet, something inside tells you otherwise. You have no proof. You can't quite put your finger on what's wrong. You let it slide. Weeks later, you discover you were right... Paco Marco is paid precisely *not* to let it slide. For thirty years, boards of directors, investment funds, and family businesses have called on him when a partner was plotting an exit, when a charismatic executive was siphoning off funds that no auditor could detect, or when a merger gave off an unmistakable whiff of deception. But his job isn't to react to the problem; it is to spot it while it is still taking shape. Here, for the first time, he shares the seven-step method he has perfected over three decades of investigation. You will learn to read the story a person's behavior writes before they even act, to distinguish the signal from the noise, and to avoid deceiving yourself--the costliest mistake of all. This isn't about superficial body-language tricks. It is the logic used by those with everything at stake--whether in a hiring decision, a negotiation, or a partnership built on trust. Once you finish this book, you will never look at the person across the table the same way again. The truth has a method. Learn yours.
