Tales of Paris in the 1920s.

What I like most about Hemmingway's book is the depth and simplicity of his prose. "I had learned already never to empty the well of my writing, but always to stop when there was still something there in the deep part of the well, and let it refill at night from the springs that fed it".

He also doesn't feel the need to explain everything. He called this writing technique the Iceberg Theory.

He hints rather than spells things out.
