why is ruth a celebrity in susies heaven?

Often when Ruth is walking the city she will stop in places that she is certain a woman has been killed, and then write the place in her journal later. For this reason, Ruth becomes a celebrity in heaven, and women line up to find out if Ruth has found where they were killed. Susie watches Ruth more closely, and she finds the moments Ruth has painful and amazing. Ruth will stop and get an image in her mind, sometimes a flash, and sometimes an entire scenario. The people in heaven feel Ruth is doing important work for them.
