There are more things in San Francisco's Chinatown than are dreamed of in Heaven and earth. In reality there are three parts of Chinatown-the part the guides show you, the part the guides don't show you, and the part that no one ever hears of. It is with the latter part that this story has to do. There are a good many stories that might be written about this third circle of Chinatown, but believe me, they never will be written-at any rate not until the "town" has been, as it were, drained off from the city, as one might drain a noisome swamp, and we shall be able to see the strange, dreadful life that wallows down there in the lowest ooze of the place-wallows and grovels there in the mud and in the dark. If you don't think this is true, ask some of the Chinese detectives (the regular squad are not to be relied on), ask them to tell you the story of the Lee On Ting affair, or ask them what was done to old Wong Sam, who thought he could break up the trade in slave girls, or why Mr. Clarence Lowney (he was a clergyman from Minnesota who believed in direct methods) is now a "dangerous" inmate of the State Asylum-ask them to tell you why Matsokura, the Japanese dentist, went back to his home lacking a face-ask them to tell you why the murderers of Little Pete will never be found, and ask them to tell you about the little slave girl, Sing Yee, or-no, on the second thought, don't ask for that story.
