"For Yo Seno," I replied, "but let us hasten. If this corridor leads to the apartment where Tavia is in prison, I cannot reach her too soon, for when Haj Osis learns that the key has been stolen he will have her removed to another prison." "He will not learn it if Yo Seno and the padwar of the guard can prevent," said Phao, "for if this reached the ears of Haj Osis it might easily cost them both their lives. They will wait for you to come that they may kill you and get the key, but they will wait outside the prison door and you will not come that way." As she spoke she started to walk along the narrow, dark corridor, leading me by the hand behind her. It was slow work for Phao had to grope her way slowly because the corridor turned sharply at right angles as it followed the partitions of the apartments between which it passed, and there were numerous stairways that led up over doorways and finally a ladder to the level above. Presently she halted. "We are there," she whispered, "but we must listen first to make sure that no one has entered the apartment with the prisoner." I could see absolutely nothing in the darkness, and how Phao knew that she had reached her destination, I could not guess. "It is all right," she said presently, and simultaneously she pushed a wooden panel ajar and in the opening I saw a portion of the interior of a circular apartment with narrow windows heavily barred. Opposite the opening, upon a pile of sleeping silks and furs, I saw a woman reclining. Only a bare shoulder, a tiny ear and a head of tousled hair were visible. At the first glance I knew that they were Tavia's. As we stepped into the apartment Phao closed the panel behind us. Attracted by the sound of our entrance, quietly executed though it was, Tavia sat up and looked at us and then, as she recognized me, sprang to her feet. Her eyes were wide with surprise and there was an exclamation upon her lips, which I silenced by a warning forefinger placed against my own. I crossed the apartment toward her, and she came to meet me, almost running. As I looked into her eyes I saw an expression there that I have never seen in the eyes of any other woman--at least not for me--and if I had ever doubted Tavia's friendship, such a doubt would have vanished in that instant, but I had not doubted it and I was only surprised now to realize the depth of it. Had Sanoma Tora ever looked at me like that I should have read love in the expression, but I had never spoken of love to Tavia and so I knew that it was only friendship that she felt. I had always been too much engrossed in my profession to make any close friendships so that I had never realized until that moment what a wonderful thing friendship might be.
