I have been reading Inspector Chen Cao mysteries set in Shanghai, so whenever I see these China Shipping North American containers, I think of him and his stories. The author, Qiu Xiaolong, now lives in St. Louis and teaches at Washington University. I find his stories rich, thoughtful page-turners. “The chief inspector does not have all the answers,” Mr. Qiu says. “Like all Chinese, he is just coming to terms with all that is changing around him.”
