One of the fictions could be 'A Good Man Is Hard to Find' by Flannery O'Connor. It's a story full of complex characters and moral lessons. O'Connor's use of Southern settings and her unique style of portraying human nature through grotesque elements is very characteristic of the kind of fictions found in the Southern Review.
There is also 'Barn Burning' by William Faulkner. Faulkner is well - known for his contributions to Southern literature. This story is about family loyalty and the struggle against class differences. His detailed descriptions of the Southern landscape and the social hierarchies within it are a great example of the type of fictions that might be in the Southern Review.
