"It is true. Here in this alien world I do not have my usual food. So I will die. To survive I need the blood of mammals. But there are none here save those seven the Other has taken. And I cannot use them for they are now spoiled." I didn't ask Lhar what sort of mammals she had in her own world. "That's what the robot wanted when it tried to stop me before, isn't it?" "He wanted you to help me, yes. But you are weak from the shock you have had. I cannot ask you—" I said, "How much blood do you need?" At her answer, I said, "All right. You saved my life; I must do the same for you. I can spare that much blood easily. Go ahead." She bowed toward me, a fluttering white flame in the dimness of the tree-room. A tendril flicked out from among her petals, wrapped itself about my arm. It felt cool, gentle as a woman's hand. I felt no pain. "You must rest now," Lhar said. "I will go away but I shall not be long." The robot clicked and chattered, shifting on its tentacle legs. I watched it, saying, "Lhar, this can't be true. Why am I—believing impossible things?" "I have given you peace," she told me. "Your mind was dangerously close to madness. I have drugged you a little, physically; so your emotions will not be strong for a while. It was necessary to save your sanity." It was true that my mind felt—was drugged the word? My thoughts were clear enough, but I felt as if I were submerged in transparent but dark water. There was an odd sense of existing in a dream. I remembered Swinburne's lines: Here, where the world is quiet, Here, where all trouble seems Dead winds' and spent waves' riot In doubtful dreams of dreams.... "What is this place?" I asked. Lhar bent toward me. "I do not know if I can explain. It is not quite clear to me. The robot knows. He is a reasoning machine. Wait...." She turned to the sphere. Its cilia fluttered in quick, complicated signals.
