The Darkness Knows

A frozen body is discovered in the icy depths of Langjoekull glacier, apparently that of a businessman who disappeared thirty years before. At the time, an extensive search and police investigation yielded no results-one of the missing man's business associates was briefly held in custody, but there wasn't enough evidence to charge him. Now the associate is arrested again and Konrad, the retired policeman who originally investigated the disappearance, is called back to reopen the case that has weighed on his mind for decades.
