The morning after an open-house showing in a posh Stockholm suburb, a father is found dead by his six-year-old daughter Astrid. There are no signs of a break-in, and the murder weapon is one of the family's own kitchen knives. The only hint that someone from the outside might be involved is that Astrid claims a strange man stroked her cheek during the night.
Police Inspector Emma Sköld takes up the case. She suspects that the man's wife could be the culprit, but when more murders occur tied to open-house showings, her theory is turned on its head. What's the truth behind the events in the ostensibly idyllic and prosperous residential area? And what is the connection between the victims?
