When Harry Hole moved to Hong Kong, he thought he was escaping the traumas of his life in Oslo and his career as a detective for good. But now, the unthinkable has happened—Oleg, the boy he helped raise, has been arrested for killing a man. Harry can't believe that Oleg is a murderer, so he returns to hunt down the real killer. Although he's off the police force, he still has a case to solve that will send him into the depths of the city’s drug culture, where a shockingly deadly new street drug is gaining popularity. This most personal of investigations will force Harry to confront his past and the wrenching truth about Oleg and himself.

尤•奈斯博，风靡全球的挪威作家，北欧犯罪小说天王，每一部作品几乎都是挪威图书畅销排行榜冠军。他拿过北欧的所有犯罪小说大奖，包括玻璃钥匙奖、挪威史上最佳犯罪小说奖、书店业者大奖等，还获得英国国际匕首奖和美国爱伦•坡奖提名，作品被翻译成40种语言，在50多个国家出版，全球销量突破3300万册。

奈斯博曾是挪威知名的摇滚巨星，白天任职于金融业，利用晚上和周末时间演出。不久，他考得金融分析师执照，被挪威最大的证券公司高薪挖走。然而工作和乐团越来越难以兼顾，濒临崩溃的奈斯博决定休半年长假。他带着笔记本电脑，跳上飞机，前往澳大利亚，在那里写下了日后让自己声名大噪的“哈利•霍勒警探”系列的第一部。

奈斯博受到英美犯罪小说名家一致推崇，迈克尔•康奈利称赞他是“我最喜欢的惊悚作家”。评论家普遍认为，奈斯博可与丹尼斯•勒翰、詹姆斯•艾尔罗伊、迈克尔•康奈利、伊恩•兰金、雷蒙德•钱德勒等名家相提并论，称他是“挪威犯罪书写的毕加索”；德国《明镜》周刊则赞他为“斯堪的纳维亚的奇迹”。他的读者族群广泛，涵盖纯文学、冷硬推理、黑色小说，以及通俗惊悚小说爱好者。
