Human trafficking has gotten enough exposure in the last ten years that its worst excesses no longer have the power to shock and distress as they should. Which perhaps also helps to explain why it periodically pops up as the basis for fiction and film, as in this rapid-fire thriller. The twist this book provides is one of perspective -- instead of seeing human smuggling through the eyes of a sympathetic Western law enforcement hero seeking a young Westerner who has disappeared in some exotic locale, we see it through the eyes of a Chinese policeman trying to find his daughter in England. The classic fish-out-of-water device is given fresh life here, simply because we're not used to seeing the West as a foreign land filled with strange signs and cultural cues. But non-English-speaking Chinese cop Ma Jian is almost completely adrift in and around Leeds as he struggles to find a Mandarin speaker to help him.
