For four months a body sat undiscovered just a few doors from the home of Chief Inspector William Wisting. Viggo Hansen was a man nobody ever noticed, even though he lived in a close-knit community. His death goes largely unreported, but does catch the attention of Wisting's journalist daughter, Line.

She decides to find out who this nondescript man really was. While Line’s research has her digging deep into the dead man’s past, Wisting focuses on the present as the body of another man is found in the forest. Wisting suspects a serial killer is at work – but his investigation only raises more questions.

For how long has this killer been active, and across how many countries? When the CIA get involved the stakes rise culminating in a deadly race against time.
