New York City, 1938: At the height of the Great Depression, when President Roosevelt is trying to keep America out of WWII, Giddy Brodsky knows she’s lucky to have a job as a cigarette girl at a Manhattan jazz club. Nevertheless, she dreams of opening her own cosmetics business and lifting her family out of the poverty-stricken Lower East Side and leaving the tenements behind. She and her family emigrated to New York after a group of Cossacks burned down her Russian village, forcing them to flee. Her memories of that event continue to haunt her.

Yet, Giddy is focused on the future…until she thinks she recognizes one of the Cossacks who participated in the pogrom that changed her life forever. Determined to get answers, —and vengeance—she enlists the help of Carter van der Zalm, the Chief Commissioner of Immigration at Ellis Island, who is hunting the same man. He suspects the Russian is involved in an assassination plot that will destroy American and Soviet relations if he succeeds, and as a regular at the jazz club who also happens to be the director of the Department of Immigration at Ellis Island. Giddy knows that he’ll be interested in finding out more about this “undesirable” and soon but when she finally tracks down the man they’re both seeking, she comes across a shocking discovery that changes everything she once held true.

With war on the horizon, Giddy finds herself in the middle of a shocking political conspiracy. It becomes clear that the future is even more uncertain than she could imagine. In the tradition of Lara Prescott’s The Secrets We Kept and Kate Quinn’s The Rose Code, The Jazz Club Spy is a glittering and gritty look at pre-war America, and the personal battle one woman wages between justice and forgiveness.
