The next morning, the two of them go to the library to check on the condition of the sleeping woman. When they arrive, they find that she is dead, and they are shocked to learn that she has been killed by her lover. They go to investigate further, and find that the man who killed her is none other than the man they saw in the library the night before. They find that he is the same man they killed the previous night, and that the woman they killed was the same woman that they killed. The doctor has told them that they are too weak to perform any more acts, so they go to bed.
