Shanghai Redemption by Qiu Xiaolong

This mystery is wrapped not only in an enigma, but in carefully applied layers of literary reference, contemporary historical realism, and socio-cultural analysis.

After 15 years of walking a knife edge of Party sensitivities, Inspector Chen is suddenly stripped of his job as the Shanghai Police Bureau's Special Case Squad. He gets a new job title -- and title is the operative word. Chen and his colleagues in the precinct know this empty 'promotion' is no more than an effort to sideline one of his investigations. But which one, and why? The wily inspector still has his brain, his poetry and other resources. Obliged to shuttle back and forth on the high speed train between Shanghai and Suzhou, where he's having his father's gravestone renovated, Chen consults his gray cells as well as trusted friends of the utmost discretion to help him investigate.

Qiu Xiaolong is a master of irony and double entendre, as we observe in this layered description of a traditional hotel room in Suzhou. "On one wall, there was an impressive row of pictures showing high-ranking party leaders in the fifties and sixties, eloquently documenting the hotel’s glorious past. The wall opposite displayed a long rice-coloured silk scroll of a seventh-century Tang poem copied by a modern calligrapher."

He portrays the status of women in China under 'Socialism with Chinese characteristics.' Among Qiu's fascinating range of characters are a Suzhou opera singer, the discarded ernai, (non-status concubine), of a Party official, and Chen's friend and former colleague, Detective Yu. Yu's intrepid wife Peqin helps her husband's inquiries in places where he is unable to venture. We also meet Party members who subtly threaten Chen using anodyne phrases, as well as expensive lawyers and American accountants who maintain that they're not obliged to tell the police a thing.

The topsy-turvy world of contemporary Shanghai is an excellent setting for this satisfying mystery. The booming city is rife with corruption, new money, 'Red Princelings' and 'Big Bucks.' While having concubines and playing mahjong are nominally illegal, "every service you can imagine" is for sale in the Heavenly World night club. In such places, officials avoid internet exposure by entering unseen through hidden underground parking access. "Red songs" enjoy an ironic comeback, while 'naked officials' ship their families and money overseas and then stay back with their ernai to see how the political wind blows. 

Meanwhile, skyrocketing Shanghai real estate prices mean many in the city must bury their dead in nearby Suzhou. Thus, the annual Qingming observance leads to a cemetery visit rush hour for the new high-speed train system to cope with.
