I jumped up and rushed from the room, but was no sooner outside my door than the voice began to die again, and in a moment the last notes had floated away. I could not determine from which direction the song had come and had no clew to guide me toward the singer. It was very late and all the house was quiet. Unable to pursue my quest, I reentered my room, but it was hours before I could compose my mind sufficiently to sleep. The possible joy that awaited me in the morning, the dreadful fear that I should be disappointed, the violent beating of my heart at every thought of Mona, and my anxiety lest she might even now be exposed to danger somewhere, all combined to keep me excited and restless the whole night long. As I lay tossing and thinking, my most serious doubt was occasioned by the reflection that people of such exalted morals would not deceive me by declaring that this singer’s name was Avis if it were not true. But then I thought further that the doctor had given Mona the name by which we knew her, and that Fronda would have just as much right to give her a new name. Perhaps her real name after all was Avis. When the welcome morning came I found the doctor and gave him a hearty grasp to show him that there had been no lapse in my mental condition, but I asked him to say nothing to Thorwald just at present about my recovery. Then we hurried down to the reception room and, early as it was, found most of the household already there. After looking eagerly around and seeing only those whom I had previously met, I inquired, with as little apparent concern as possible: “Hasn’t Avis appeared? I thought she was an early riser.” To which Fronda quickly replied: “Oh, Avis was up half an hour ago, and asked me to excuse her to the company, saying she was going to spend the morning with a friend she met yesterday.” This was a hard blow for me, and it was with difficulty that I restrained my impatience, but I was a little consoled with the idea that the morning only was to be consumed by this visit, and that we might look for a return by noon. After breakfast, when Proctor had gone to the observatory and Fronda and her daughters were showing Zenith about the house, the doctor begged Thorwald to resume the talk begun on board the ship, which had been interrupted by the discovery of land. As Thorwald expressed a willingness to comply, the doctor continued: “You were trying to convince me of the probability of life in other worlds besides the earth and Mars, and in your attempt to show a likeness between the earth and other parts of the universe, you were speaking on the interesting subject of meteorites.” “I remember,” answered Thorwald, “I was just asking you what theory you of the earth hold on that important topic.” CHAPTER XVI AN UNLIKELY STORY
