The first in an exciting new series from the author of THE SILENCE OF THE SEA, winner of the 2015 Petrona Award for best Scandinavian Crime Novel. The only witness to a shocking murder is the victim's seven-year-old daughter, Margret. The police turn to the Children's House for their expertise in childhood trauma. The manager Freyja doesn't much like the police - especially the detective in charge, Huldar. But she does want to help them protect Margret. And when more people die - their murders heralded by strange messages, texts, and strings of numbers - they will have to work together to crack the riddle before they become targets themselves.
