In the middle of a hard-won morning nap in the basement of police headquarters,
Carl Morck, head of Department Q, receives a call from a colleague working on th
e Danish island of Bornholm. Carl is dismissive at first, but then he receives s
ome shocking news. Carl then has no choice but to lead Department Q into the tra
gic cold case of a vivacious seventeen-year-old girl who vanished from school, o
nly to be found dead hanging high up in a tree.
The investigation will take t
hem from the remote island of Bornholm to a hidden cult, where Carl and his assi
stants must stop a string of new murders by a skilled manipulator who refuses to
let anything-or anyone-get in the way.
