小鎮傳出男孩從晚宴上失蹤,而島上難民營也傳出另一個男孩失蹤。原先只是簡單地尋找失蹤孩子,卻讓Maria Wern陷入一堆無法預知的陰謀之中,有個人的背叛,也與國際犯罪有關。A ten-year-old boy disappears from a dinner in a little fishing village, while another vanishes from a refugee camp on the island. These are but the first in series of frightening events to take place on the island of Gotland, where a string of brutal murders are committed in quick succession. And what starts out as the search for a missing child, leads Maria Wern and her colleagues ever deeper into a nest of hidden agendas, personal betrayals.
