The reopening of a cold case brings sketchy characters out of the woodwork and triggers deep emotion in a retired detective.
While exploring an Icelandic glacier, a group of German tourists stumble upon the well-preserved corpse of Sigurvin, a young man who disappeared 30 years ago. Konrád, the retired detective who worked the case, gets a call from his friend Svanhildur, a pathologist at the National Hospital, urging him to take a look at the body. A large head wound confirms that the death was most likely murder. Konrád has long believed that Hjaltalín, a man who threatened Sigurvin, was responsible for his death. The suspect was never brought to justice but suffered public infamy. When Hjaltalín, now elderly and frail, is taken into custody, he requests a meeting with Konrád, professes his innocence, and pleads to be exonerated—and then, days later, he dies. Once Konrád reluctantly begins a new investigation, he notices glaring omissions in the record and gets an odd visit from a woman whose brother, killed in a suspicious car accident, may have witnessed the crime as a child. His labyrinthine probe unearths secrets that have been buried for decades. Indridason methodically builds a portrait of Iceland with a large cast of nuanced characters unsettled by past events. In dredging up the past, Konrád must also confront his complex relationship with his own abusive father, whose murder was unsolved as well.
The intricate plot poignantly depicts community crosscurrents, past and present.
