Children of the Luna

In 1939 ten people on an outing are caught in a mountain cabin during a snow storm together with the cabin's hostess. The first night one of them is killed, and it can not have been someone from the outside so the killer must be someone in the cabin...

Swedish intelligence officer Carl Hamilton's 7-year-old goddaughter Nathalie is kidnapped. When the kidnapping's underlying motive becomes known, the Swedish authorities assume a passive role, forcing Hamilton to action. With the help of international contacts, Hamilton manages to get them on track. Hamilton, along with some military colleagues, plans a daring rescue mission.
