Time to immerse myself again in Scandinavian crime fiction, although this is a re-read of a book that's been recently re-released. The first in the Stubo and Vik series.
From the Blurb:
"A serial killer is on the loose, abducting and murdering children in a way that confounds the police, before returning the child's body to the mother with a desperately cruel note: You Got What You Deserved. It is a perplexing and terrible case, and Police Superintendent Adam Stubo is in charge of finding the killer. In a desperate bid to get some answers, he recruits legal researcher Johanne Vik, a woman with an extensive understanding of criminal history. So far the killer has abducted three children, but one child has not yet been returned to her mother. Is there a chance she is still alive? And can the pair solve the case in time?"
One afternoon after school, nine-year-old Emilie doesn't come home. Her father finds the backpack from her late mother, that would never be abandoned willingly. A week later, a five-year-old boy goes missing. And then another child.
Meanwhile, Johanne Vik, a former FBI profiler with a troubled past and a difficult young daughter, tries to overturn a decades-old false murder conviction. Police Commissioner Stubo lost his wife and daughter, has only his grandson left, and needs to solve the case. Johanna resists helping until the bodies return to their homes with notes "You got what you deserved".
