Overview: PAO is confused as many famous doctors have disappeared. As most of the doctors' families receive letters from them which state that they are save, CHIU waits outside SIT's house. It is because SIT's family still have not received any information from SIT. At last CHIU finds a masked man sending the letter. The masked man manages to escape. CHIU suspects that the masked man is FAY who has disappeared for seven years. Meanwhile the Mother Queen suffers from incurable disease. The Emperor orders HAU to deliver the "Thousand-year Amber" to the Mother Queen for treatment. However it is stolen by FAY that night. HAD's daughter-in-law is killed.
