I was drawn to this as it is a Crime Thriller/procedural set in China. The author's introduction was one of the best insights into a novel I had read. As for the plot, it gets off to a good start when a burning body is discovered in a park.
The main protagonists are an American Pathologist, Margaret Campbell on loan to the Beijing police and detective Liyan.
For an intelligent woman I found some of Campbell's actions and motives didn't ring true mainly before setting off from Chicago can't be bothered reading information provided for her about Chinese Culture, she seemed to fit the cliched stereotypical American abroad.
May liked to impart information about genetics, Chinese culture and police procedures and these at times became info dumps in the form of over long dialogue and unnecessary long paragraphs.
It is not until the last 100 or so pages does the action and the stakes increase for the characters and the book becomes all the better for it. It was a shame it didn't occur before then, or maybe a serious edit.
