How is weather used as imagery in the novel, Faceless Killers?

The weather reflects the tone of the novel. As the anti-foreign sentiment comes to a boil, the winds pick up and cause a violent storm across the countryside. As the investigation grinds to a halt, the snows set in, and Sweden is entrapped in a frozen, long winter. Only when the snows are thawed does Wallander's personal world seem to calm, and he finally experiences a breakthrough in the Lunnarp case.
