In this chapter, we learn that the woman in question, zheng lun, has already died. We also learn that she had been sick for both of her parents that night, and that she also called in sick to the outside world. We learn that this is not the first time that she has been in touch with the outside, and she has also been in contact with the dead. The two men decide that they need to find out if zhenglan is the murderer, or if another person is pretending to murder others. They decide to watch over the two men as soon as they see the two women arrive.
