Romeo and Juliet live in a luxury home. They neither participate in social activities and have not grown with others. One day, a maid hysterically ran to tell the housekeeper, saying that they died on the floor of the bedroom. The housekeeper quickly came to the bedroom with the maid, and found that the two bodies were lying on the floor as the maid. There is no signs of violence in the room, and no imprint is left on the body. The murderer seems to be not broken, because there are no other signs that there are some broken glasses in the floor, it can prove this. The housekeeper excludes the possibility of suicide; poisoning is also impossible, because dinner is prepared by him, personally serving. When checking the body, the housekeeper did not find the cause of death, but noted the carpet and wet.
How did they die? Who killed them?
