Already the 12th book of one of the world's most successful crime series Harry Hole by Jo Nesbo
Harry is facing the most complicated case of his career, and he is not sure he can even work. His idyllic marriage to Rachel is long gone. Working at the academy he enjoyed is gone too. All he had left was his faithful friend Jim Beam, and a place in the office where he was just sorting papers. It seems to him that he stands above the precipice and may fall at any moment. Or maybe he has already fallen and it's too late for everything. He had woken up many times and had no idea what had happened. Mostly he had a classic "window" and a real hangover.
This time it's much worse. He has no idea that something is in a terrible mess, because when he wakes up, he has blood on his hands and trousers. He doesn't remember anything. He doesn't even know what happened at Jealousy's bar in the evening. Gradually, small fragments of events come to light, and everything looks too bad to be true. Harry Hole begins to wish he didn't wake up at all. Because even the worst dream in the world is far better than the harsh reality that it has to face.
