Have you ever been lied to? Of course you have, whether you knew it or not.

Ever caught a spouse, business partner, parent, boss, or child brazenly lying right to your face? What if you could tell someone was lying, just by listening to them, and observing their action and behavior? How to Spot a Liar is the first book that gives you the tools to figure out what's really going on: to gain the upper hand in salary negotiation, move a prospective client toward the outcome you desire, and find out why you need to end a business or personal relationship.

Who needs How to Spot a Liar? Anyone with a cheating spouse or manipulative boss. Anyone conducting job interviews or cold-calling prospective customers. Lawyers who need to "read" witnesses or jurors. Anyone trying to survive the dating scene or faced with a string of business meetings with clients. Anyone who has teenagers at home or works on Capitol Hill. Anyone whose success and happiness depends on clear interaction with others.

And anyone who wants to become just a bit more inscrutable, in business, life... even at the poker table!
