A secret aria of courage and suspense Europe, 1937. Two British sisters: one a dowdy typist, the other a soon-to-be famous romance novelist. One shared passion for opera. With war clouds gathering and harassment increasing, the stars of Continental opera, many of whom are Jewish, face dark futures under the boot heel of the Nazis. What can two middle-aged British spinsters do about such matters? They can form a secret cabal right under Hitler's nose and get to work saving lives. The sisters conspire to bring together worldwide opera aficionados and insiders in an international operation to rescue Jews in the opera from the horrific fate that everyone intuits is coming. By the time war does arrive, the Cooks and their operatives have plucked over two dozen Jewish men and women from the looming maw of the Holocaust and spirited them to safety in England. Packed with original research and vividly told with suspense, hope, and wonder by award-winning New York Post investigative journalist Isabel Vincent, this singular tale reveals many new details of the seemingly naïve and oblivious Cook sisters' surreptitious bravery, daring, and passionate commitment as the two mount a successful rescue mission that saves dozens of lives and preserves the opera they love for another generation.
