Adventure, of course. It's in the genre name. This could include things like dangerous encounters, narrow escapes, and exciting journeys through the sandy landscapes.
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.
Colonel Terry Childers was involved in a complex situation. He was a military man. He faced certain accusations which put him in a difficult spot. His case likely involved issues related to military protocol and decision - making during a particular event.
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.
