Hypothermia

At the start of Indridason's powerful sixth Reykjavík thriller (after Arctic Chill), the body of María, a woman ravaged by guilt, is found hanging in her holiday cottage, an apparent suicide. As Erlendur, a police detective who works largely alone because he prizes solitude above all else, doggedly interviews those close to María—her husband, her relatives, her friends—in an unofficial effort to understand what might have driven her to take her own life, he unravels an ingenious and sinister plot. Complicating his investigation are the ghosts from his personal and professional past: his failed marriage and his shaky relationships with the son and daughter who grew up without him, as well as unsolved missing-persons cases he still feels morally compelled to pursue. Most scalding of all is his memory of the blizzard that he barely survived as a boy but in which his younger brother perished, the tragic event that shaped Erlendur's later life and lends mythic resonance to Indridason's remarkable novels.
