Djävulsstjärnan by Jo Nesbø

A troubled Oslo detective is pulled into a harrowing hunt for a meticulous serial killer who leaves a five-pointed star as a calling card; as he pieces together cryptic clues, the investigation exposes dark secrets and institutional corruption, tests his fragile personal life and sobriety, and turns into a tense cat-and-mouse race to stop the killer before more lives are lost.
