A man is making a crude leather mask with slits for eyes and mouth, and an iron spike fixed in the middle of the forehead. It is a 'death mask', once used by Icelandic farmers to slaughter calves. He has revenge in mind.
Meanwhile, with Detective Erlendur absent, his baseball-loving colleague Sigurdur Óli is in the spotlight. A school reunion has left Sigurdur Óli dissatisfied with life in the police force. Iceland is enjoying an economic boom and young tycoons are busy partying with the international jet set. In contrast, Sigurdur Óli's relationship is on the rocks and soon even his position in the CID is compromised: when he agrees to visit a couple of blackmailers as a favour to a friend he walks in just as a woman is beaten unconscious. When she dies, Sigurdur Óli has a murder investigation on his hands.
The evidence leads to debt collectors, extortionists, swinging parties. But when a chance link connects these enquiries to the activities of a group of young bankers, Sigurdur Óli finds himself investigating the very elite he had envied.
Moving from the villas of Reykjavík's banking elite to a sordid basement flat, Black Skies is a superb story of greed, pride and murder from one of Europe's most successful crime writers.
