Ever since I read The Boy in the Suitcase by this talented Danish duo, I have been hooked by their writing. This newest book follows in the same vein—Nordic noir fiction focused on the criminal mistreatment of women and children. In it, Danish Red Cross nurse Nina Borg is reintroduced when Natasha, one of the women who took refuge at the crisis center where Nina works, shows up on the news as being a suspect in the death of her abusive fiancé. As Nina struggles to both understand the complexity of Natasha’s predicament and protect Natasha’s daughter, she realizes there is much she doesn’t know about Natasha and her past. The mystery has long and bloody roots, going back to a famine that devastated Stalinist Ukraine in 1934, when a 10-year-old girl with the voice of a nightingale sang her family into shallow graves. A beautiful but suspenseful read that will keep you guessing until the end.
