A seemingly straightforward investigation into marital infidelity leads a PI and his ex-con assistant on a murderous trail, in a sophisticated, riveting historical Nordic Noir thriller set in interwar and prohibition-era Norway.

Oslo, 1938. War is in the air and Europe is in turmoil. Hitler’s Germany has occupied Austria and is threatening Czechoslovakia; there’s a civil war in Spain and Mussolini reigns in Italy.

When a woman turns up at the office of police-turned-private investigator Ludvig Paaske, he and his assistant – his one-time nemesis and former drug-smuggler Jack Rivers – begin a seemingly straightforward investigation into marital infidelity.

But all is not what it seems, and when Jack is accused of murder, the trail leads back to the 1920s, to prohibition-era Norway, to the smugglers, sex workers and hoodlums of his criminal past ... and an extraordinary secret.

Both a fascinating portrait of Oslo’s interwar years, with Nazis operating secretly on Norwegian soil and militant socialists readying workers for war, The Assistant is also a stunningly sophisticated, tension-packed thriller – the darkest of hard-boiled Nordic Noir – from one of Norway’s most acclaimed crime writers.
