Reckoned as the literary pioneers of L.A., James M. Cain and Horace McCoy share many similarities. Firstly, they had the same urban experiences. South California was the start of their literature works, but it also was the end of disastrous destiny of the heroes in their works. Secondly, the heroes in their works had no sense of belonging. They left their hometown and deluded to this spiritual barren land for hopes and dreams, where the relationship between human beings is stricken dramatically and collapses at last, especially that between men and women, which is nothing but lust and sex. Thus, the city of L. A. is given a brand new literary identity by the two pioneers.
