The latest thrilling instalment in Indridason's CWA Gold Dagger Award-winning Reykjavik Murder Mystery series. On an icy January day the Reykjavik police are called to a block of flats where a body has been found: a young, dark-skinned boy, frozen to the ground in a pool of his own blood. Erlendur and his team embark on their investigation with little to go on but the news that the boy's Thai half-brother is missing. Is he implicated, or simply afraid for his own life? The investigation soon unearths tensions simmering beneath the surface of Iceland's outwardly liberal, multicultural society.
