Francis Macomber Timeline and Summary

The Macombers are drinking gimlets with Wilson, and Macomber can't drop the subject of his failure to go after a lion he was hunting.
To make up for his cowardice, Wilson and Macomber make plans to shoot a buffalo the next day.
Later that afternoon, Wilson and Macomber go out to shoot impala; Macomber has some success.
That night after dinner Macomber goes over the events of the day. Lying alone in his tent, he thinks of how disgusted his wife is with him.
Hey, now that we think of it, where is his wife? She's gone until 3am, when she returns to their tent having been with Wilson.
At breakfast in the morning, the Macombers and Wilson discuss the day's hunt.
They all set off to hunt buffalo.
Macomber hits some buffalo but must finish the job. He feels untold joy. His hunting success has made him a changed man.
But then, as he shoots the charging buffalo to finish the beast off, Margot finishes him off instead, shooting her husband from the back of the nearby car.
