How does John Grisham use imagery in The Broker?

Imagery:

"In a very nervous city, the day began with the pardon storming onto center stage and competing with a new President and his first full day in office."

"He was free, many years ahead of schedule, and sitting in a rustic little café in an Italian town he'd never heard of, drinking a nice local wine, and inhaling the smells of a delicious feast."
