There, one night, the party's charismatic leader - and Marie's boyfriend - Falko Reinhardt vanished without a trace. But were the relationships between this group of friends and comrades all they appeared to be? What did Marie see, that made her run for her life that day? And could both mysteries be linked to Falko's research into a cell of Norwegian Nazis he suspected may still be active?It soon becomes clear that Marie's death is not only a complex case in its own right, but will act as a catalyst in a dark set of events which will leave K2 and Patricia confronting their most dangerous and explosive investigation yet. And as the pair work hard to unravel the clues before Marie's killer can strike again, the detective fails to notice that his young assistant has her own problems to face . . .

Oslo, 1968. Ambitious young detective Inspector Kolbjorn Kristiansen is called to an apartment block, where a man has been found murdered.The victim, Harald Olesen, was a legendary hero of the Resistance during the Nazi occupation and at first it is difficult to imagine who could have wanted him dead. But as Detective Inspector Kolbjorn Kristiansen (known as K2) begins to investigate, it seems clear that the murderer could only be one of Olesen's fellow tenants in the building.Soon, with the help of Patricia - a brilliant young woman confined to a wheelchair following a terrible accident - K2 will begin to untangle the web of lies surrounding Olesen's neighbours; each of whom, it seems, had their own reasons for wanting Olesen dead. Their interviews, together with new and perplexing clues, will lead K2 and Patricia to dark events that took place during the Second World War . . .The Human Flies by Hans Olav Lahlum is a gripping, evocative and ingenious mystery - the first in a series featuring K2 and Patricia - which pays homage to the great Agatha Christie and will plunge readers into Norwegian history, and into a world of deceit and betrayal, revenge and the very darkest murder.
