The No.1 bestselling author is back with a powerful exploration of what our interactions with strangers tell us about who we are. Why are we so bad at judging someone or detecting a lie? Why do we so often fail to 'get' other people? Through a series of puzzles, encounters and misunderstandings, from unknown stories to infamous legal cases, Gladwell takes us on a journey through the unexpected. From the author of "The Tipping Point", "Blink", and "Outliers".
