"How much further can he take us?" Jean asked. "After the first drop back at the hutch, it seems to me the tunnel has been level."
"A floor can be deceptive. We could have been moving down a gradual slope for miles."
Jean said nothing. The going was easier now, this tunnel being lighted at intervals by the strange overhead bulbs. Rex asked, "Are you sore at me for what happened back at the farm? For not telling you the truth?"
"No. We're in too much trouble to waste time being angry. What's done is done. Only the future is important now."
Rex could have made his self-recrimination vocal but he felt that too would be a waste of time. He said, "Didn't anybody—any of you Terrans know about the opening in that hutch?"
"I'm sure no one did—except perhaps Tommy." She thought that over and added, "No—that's absurd. If Tommy had known it he wouldn't have been able to keep it to himself."
"Maybe they'll hunt around and find it."
"Maybe—but I hope they don't."
"Why not?"
"If they find the opening they'll come looking for us. These Martians are hostile. Some of our men might be killed and they have wives and families."
