THANK YOU, MR. MOTO was the second in the Mr. Moto series, begun shortly after Marquand returned from his 1935 China trip. As was his custom, Marquand used two young people as the protagonists who found themselves unwittingly immersed in a mystery. While they struggled to solve the dilemna, the amateur sleuths were aided by Mr. Moto who appeared at crucial moments to make the heavy decisions and do the necessary liquidating.
Marquand does a good job of describing the tensions in pre-World War II China and between rival Japanese interests. In order to enjoy the story, the reader will have to ignore some 1930's racial stereotypes - although the author does make an obvious effort to destroy many myths.
