What is the author's style in The Short, Happy Life of Francis Macomber by Ernest Hemingway?

Irony is an essential stylistic element of this story. The most obvious and striking example of irony is the title itself. Certainly, Macomber's life is "short," but is it "happy"? It is also ironic that his wife, the very person who should protect him, is the cause of his death. Furthermore, the fact that it may have been her impulse to protect Macomber which destroys him makes the climax of the story ironic. Hemingway uses irony to provide enough ambiguity in the narrative for the outcome of the story to be unclear.
