Miami, 1951. 25-year-old Kay Thompson has earned the trust of former First Lady and celebrated human rights leader Eleanor Roosevelt—both as her secretary and ally in advocacy. But when the duo becomes entangled in a deadly international mystery connected to a famous performer, can Kay truly trust her own instincts before it’s too late?

With a flurry of UN engagements bringing Mrs. Roosevelt to vibrant South Beach, Kay is thrilled to escape the post-Christmas blues in Washington, DC—and distance herself from the sting of her recent breakup with private investigator Tim O’Malley. The dizzying sights and sounds of Miami reach their peak at the Copa City Club, where a late-night meeting with singer Josephine Baker reveals a troubling truth: Baker’s bold stand against segregation has made her a target.

Josephine dismisses the threats. But Rosaleen her cautious young assistant with big dreams—is deeply afraid. That’s why it’s a stunning shock when a dead man turns up in Josephine’s dressing room and Rosaleen is the one arrested for his murder. Determined to exonerate her new friend, Kay joins forces with Mrs. Roosevelt and her former flame to confront the sinister forces lurking just beneath Miami’s glittering Art Deco surface. But when a killer’s scheme comes into sharp focus, Kay must act swiftly in a quest for justice that proves far more dangerous than she ever bargained for . . .
