On a cold day in Reykjavik, a baby goes missing from her pram. When the child’s blanket washes up on the beach, and the mother is found dead, everyone’s worst fears seem to have been realised. Eleven years later, and detective Huldar and child psychologist Freyja are now working in the same police building, on the same team. Freyja believes that personal and professional relationships must remain separate, however hard that may be. But when a woman’s dismembered body is found in a deserted car, her head missing, and Freyja and Huldar find themselves working on the same case, the secrecy around their affair threatens to crack.
