Pan Dan Chee ignored my flippancy. "We saw a light and we heard a laugh," he said thoughtfully. "What does that convey to you?"

"The same thing that it conveys to you," I said: "that there is some one down here in the Pits of Horz beside us."

"I do not see how that can be possible," he said.

"Let's investigate," I suggested.

With drawn swords we advanced; for we did not know the nature nor the temper of the owner of that laugh, and there was always the chance that an ulsio might leap from one of the dungeons and attack us.

The corridor ran straight for some distance, and then commenced to curve. There were many branches and intersections, but we kept to what we believed to be the main corridor. We saw no more lights, heard no more laughter. There was not a sound in all that vast labyrinth of passageways other than the subdued clanking of our metal, the occasional shuffling of our sandalled feet, and the soft whisperings of our leather harnesses.

"It is useless to search farther," said Pan Dan Chee at last. "We might as well start back."

Now I had no intention of going back to my death. I reasoned that the light and the laugh indicated the presence of man in these pits. If the inhabitants of Horz knew nothing of them; then they must enter the pits from outside the citadel, indicating an avenue of escape open to me. Therefore, I did not wish to retrace our steps; so I suggested that we rest for a while and discuss our future plans.

"We can rest," said Pan Dan Chee, "but there is nothing to discuss. Our plans have all been made for us by Ho Ran Kim."

We entered a cell which contained no grim reminders of past tragedy; and, after wedging one of our torches in a niche in the wall, we sat down on the hard stone floor.

"Perhaps your plans have been made for you by Ho Ran Kim," I said, "but I make my own plans."

"And they are-?" he asked.

"I am not going back to be murdered. I am going to find a way out of these pits."

Pan Dan Chee shook his head sorrowfully. "I am sorry," he said, "but you are going back to meet your fate with me."

"What makes you think that?" I asked.

"Because I shall have to take you back. You well know that I cannot let a stranger escape from Horz."

"That means that we shall have to fight to the death, Pan Dan Chee," I said; "and I do not wish to kill one at whose side I have fought and whom I have learned to admire."

"I feel the same way, John Carter," said Pan Dan Chee. "I do not wish to kill you; but you must see my position—if you do not come with me willingly, I shall have to kill you."
