From the Nordic noir duo who brought you The New York Times bestseller The Boy in the Suitcase comes a chilling new thriller with a mystery seventy-years in the making.

Nina. Natasha. Olga. Three women united by one terrifying secret. But only one of them has killed to keep it.

Natasha Doroshenko, a Ukrainian woman who has been convicted of the attempted murder of her Danish fiance, escapes police custody on her way to an interrogation in Copenhagen’s police headquarters. That night, the frozen, tortured body of Michael, the ex-fiance, is found in a car, and the manhunt for Natasha escalates. It isn’t the first time the young Ukrainian woman has lost a partner to violent ends- her first husband was also murdered, three years earlier in Kiev, and in the same manner- tortured to death in a car.

Danish Red Cross nurse Nina Borg has been following Natasha’s case for several years now, since Natasha first took refuge at a crisis center where Nina works. Nina, who had tried to help Natasha leave her abusive fiance more than once, just can’t see the young Ukrainian mother as a vicious killer. But in her effort to protect Natasha’s daughter and discover the truth, Nina realizes there is much she didn’t know about this woman and her past. The mystery has long and bloody roots, going back to a terrible famine that devastated Stalinist Ukraine in 1934, when a ten-year-old girl with the voice of a nightingale sang her family into shallow graves.
