"What do they want of pilots underground?"
"I couldn't quite get that. There was another thought that I am not sure that I interpreted correctly. If I did, there is some man of the upper world down here in a position of considerable authority among them. He has some use for pilots, but what use, I don't know. We are to be held until he is consulted."
"Who could it be?"
"I can only think of one man. Carnes, and I hope I'm wrong. I don't have to name him."
"You mean—?"
"Ivan Saranoff. We haven't heard of him or had any activity from him for the last eight months. We know that he had a subterranean borer with which he has penetrated deep into the earth. Isn't it possible that he has, at some time in his explorations, come into contact with these fellows and made friends with them?"
"It's possible, Doctor, but I hoped we had killed him when we destroyed his borer."
"So did I, but he seems to bear a charmed life. Several times we have thought him dead, only to have him show up with some new form of devil's work. It is too much to hope that we have succeeded in doing away with him. Did you notice one thing? Those fellows were helpless while I held the light on them. The one which was holding us captive got so interested in the discussion about our fate that he momentarily forgot us. That was when I got my light. Until I turned the light away from them, we were free men."
