Estranged from Rakel and her son Oleg, whom you may know from previous books, Harry Hole returns to Olso when Oleg, now a drug dealer, kills another junkie. The youth looks very guilty but Harry Hole finds flaws in the obvious explanation and sets about exonerating Oleg. He dives head first into the Oslo underworld and, discovering a new synthetic form of heroin is on the market, becomes the target of a viscious gang of Russian traffickers. Harry Hole will not let go and this proves to be his undoing in this must-read book especially if you love Scandinavian crime fiction. Every so often a strange vagrant called Cato drifts into his life sharing strange advice. The Phantom is darker than a coal mine at night and has an ending that will hit you like a brick in the face. You have been warned.
