The Murder of Mr. Ma by John Shen Yen Nee and S.J. Rozan
Lao She is an unassuming, respectable young scholar from China who has emigrated to London and now teaches Chinese language at Oxford and wants to write a novel. Then he is called to the home of philosopher Bertrand Russell who needs his assistance - in breaking a friend out of jail. It's during this errand that Lao meets Judge Dee Ren Jie. I do have to say it's an interesting meeting and sets the tone for the rest of the book. Judge Dee is in London to investigate the death of Mr. Ma, a fellow member of the Chinese Labor Corps who served in France during the First World War and was allowed to come to London afterward. Lao, who is more familiar with the city, offers to help Dee, but soon another Chinese man is found dead and the whole situation becomes more complicated.
