"The Shadow Killer is the extraordinary second book in the compelling new series from award-winning Icelandic author Arnaldur Indridason, following The Shadow District. ... A man is found murdered in a small apartment in Reykjavík, shot in the head with a pistol. The police's attention is immediately drawn to the foreign soldiers who are on every street corner in the summer of 1941. So begins officers Flóvent and Thorson's investigation, which will lead them down a path darker than either of them expected, and force them to reckon with their own demons." --
