London, 1936. Lena Aldridge is wondering if life has passed her by. The dazzling theatre career she hoped for hasn’t worked out. Instead, she’s stuck singing in a sticky-floored basement club in Soho, and her married lover has just dumped her.
 
But Lena has always had a complicated life, one shrouded in mystery as a mixed-race girl passing for white in a city unforgiving of her true racial heritage. She has nothing to look forward to—until a stranger offers her the chance of a lifetime: a starring role on Broadway and a first-class ticket on the Queen Mary bound for New York. 
 
After a murder at the club, the timing couldn’t be better, and Lena jumps at the chance to escape England. But when a fellow passenger is killed in a strikingly familiar way, Lena realizes that her greatest performance won't be for an audience, but for her life.
