How does Henning Mankell use imagery in Faceless Killers?

"Suddenly he knows that Johannes is dead. He shines his torch inside and blinks hard before he forces himself to look." —Chapter 1, page 5

"When he went back to his office he could feel a gnawing in his stomach. But was it hunger or anxiety?" —Chapter 3, page 30

"Crosses had been burned at night in the courtyard, rocks had been thrown through windows, buildings had been spray-painted with slogans." —Chapter 4, page 42
