Motivated by the habits of a lifetime, I strained my eyes in search of Llana of Gathol, who perhaps was down there somewhere in the courtyard; and then, realizing the futility of looking for her, I whistled. There was an immediate response from below and I sprang down from the roof. It did not take us long to locate one another; and as we were not challenged, I assumed that we were fortunate enough to be alone.

Llana touched my hand. "I thought that you would never come," she said. "Rojas told me about the duel that you were to fight; and while I had no doubts about your swordsmanship, I realized that there is always the danger of an accident or trickery. But at last you are here; how strange it is not to be able to see you. I was really quite frightened when I stepped out here into the courtyard and discovered that I could not even see myself."

"It is the miracle of invisibility that will save us," I said, "And only a miracle could have saved us. Now I must get you to the roof."

There was no overhanging tree in this courtyard, and the roof was fifteen feet above the ground. "You are about to have an experience, Llana," I said.

"What do you mean?" she asked.

"I am going to toss you up onto the roof," I told her, "and I hope you land on your feet."

"I am ready," she said.

I could see the roof all right, but I couldn't see Llana; all I could do was pray that my aim would be true. "Keep your whole body perfectly rigid," I said, "until I release you; then draw your feet up beneath you and relax. You may get a bad fall, but I don't think that it can hurt you much; the roof is heavily padded with vines."

"Let's get it over," said Llana.

I grasped one of her legs at the knee with my right hand and cradled her body on my left forearm; then I swung her back and forth a couple of times, and tossed her high into the air.

Llana of Gathol may have been invisible, but she was also definitely corporeal.

I heard her land on the roof with anything but an invisible thud, and I breathed a sigh of relief. To spring lightly after her was nothing for my earthly muscles, and soon a low whistle brought the three of us together. I cautioned the girls to silence, and we walked hand in hand in the direction of the flier.

This was the moment that aroused my greatest apprehension, as I realized that the flier might be surrounded by invisible warriors; and, as far as I knew, the only sword among us was the one I had taken from the warrior I had killed in the courtyard; but perhaps Rojas had one.

"Have you a sword, Rojas?" I whispered.

"Yes," she said; "I brought one."
