How does the author contrast the country with the city in the novel, Easy Prey?

Davenport begins the book out at his country cabin on a lake. He goes for a friendly morning of companionable fishing with a friend. We see how he allows a neighbor to store a tractor at his place, and then, as a favor, Davenport hauls a boat back to a farmer's house. The lake community appears to resemble an oldfashioned small town of friends. As soon as Davenport heads back into the big city, he meets the woman he is going to consider committing adultery with, and he is swept into the big, drug-related murder case. All the peace and quiet of the country have vanished.
