Well, Erskine Caldwell novels often deal with the lives of the poor and working - class in the South. His writing is very realistic and sometimes a bit gritty.
I'm not sure specifically which Erskine Caldwell novel was published in 1933 without more research. Caldwell was known for works that often explored the lives of poor Southerners in the United States. His novels typically depicted the hardships, social issues, and human relationships in that region. Maybe it was one of his early works that started to gain him recognition for his unique style of portraying the rural South.
The'mockingbird' in Erskine's novel might be a symbol. It could represent innocence. For example, in some novels, the mockingbird is a creature that does no harm but is often targeted, much like innocent characters in the story.
In my opinion, Erskine Calwell's novels were not sexualized. They tended to deal with deeper and more complex issues rather than emphasizing sexual content.
One possible theme could be poverty. Caldwell often wrote about the poor in the South, so it's likely that this 1933 novel also explored the hardships of those living in poverty.
I'm not sure if there are reviews available yet. It depends on how recently it was released. If it's just come out, there may only be a few early reviews from bloggers or reviewers who got advance copies. But if it's been out for a while, you can check popular book review sites like Goodreads or Amazon to see what readers are saying.
The characters in Erskine Caldwell short stories are very distinct. They are often simple folk, but with complex emotions and situations. For example, in some stories, the characters struggle between their moral values and the harsh circumstances they find themselves in. His use of dialogue helps to bring these characters to life.
One characteristic could be his focus on character development. He might create complex characters with their own dreams, flaws, and growth throughout the story.
