In February 1943, four thousand Jews went underground in Berlin. By the end of the war, all but a few hundred of them had died in bombing raids or, more commonly, in death camps. This is the real-life story of some of the few of them - a young mother, a scholar and his countess lover, a black-market jeweler, a fashion designer, a Zionist, an opera-loving merchant, a teen-age orphan - who resourcefully, boldly, defiantly, luckily survived. In hiding or in masquerade, by their wits and sometimes with the aid of conscience-stricken German gentiles, they survived. They survived the constant threat of discovery by the Nazi authorities or by the sinister handful of turncoat Jewish "catchers" who would send them to the gas chambers. They survived to tell this tale, which reads like a thriller and triumphs like a miracle.
