Book excerpt: It took three generations to build Barneys into the world's most fabulous clothing store--and less than a decade to tear it down. This fascinating book is at once a family saga, a cautionary business tale, and a riveting, superbly detailed, behind-the-scenes account of how a secondhand store founded on pluck and chutzpah grew into a glittering international retail empire, only to founder on greed and hubris.
