1936, September 17th, 1am… In the middle of Harlem, in the dead of night, a woman falls from a second storey window. In her hand, she holds a passport and the name written on it is Lena Aldridge… Nine days earlier… Lena arrived in Harlem less than two weeks ago, full of hope for her burgeoning romance with Will Goodman, the handsome musician she met on board the Queen Mary.

Will has arranged for Lena to stay with friends of his, and this will give her the chance to find out if their relationship is going anywhere. But there is another reason she's in Harlem – to find out what happened in 1908 to make her father flee to London. As Lena's investigations progress, not only does she realise her father lied to her, but the man she’s falling too fast and too hard for has secrets of his own.

And those secrets have put Lena in terrible danger…
