Inspector Chen goes to the US and finds that politic is all the same everywhere. Or something like that. This is the weakest of the Qiu's Inspector Chen series I've read so far. The plot is entirely focused on the corruption of the Chinese political class, the Red Rats, their influence, the way they steal money and flee the country. Chen is given the mandate to find the corrupted and to bring them to justice but he finds that it's all a mascarade in the end. The whole US trip is only a diversion and a lovely aside. The conclusion probably opens the way for the next book since Chen decides to act against what he is told to do.
