What does the rain come to symbolize in the novel, Jar City?

The rain in this book reflects the Holberg case. When the book begins the rain has started, but it is nothing out of the ordinary. However, as the book progresses the rain seems to worsen to the point that it is close to breaking Iceland’s record. This is the point when the Holberg case has become complicated by the search for Grétar’s body and the search for Audur’s brain is underway. The heavy rainfall in this section symbolizes the difficulty and status of the case. When Erlendur finds Einar at Audur’s grave, the rain seems to lighten up. This is symbolic of the case coming to an end. The suffering that characters like Einar and Katrin have endured is also ending.
