“You mean you tortured him?” cried Lang, remembering the burn upon Rockett’s arm.

“I wouldn’t call it torture, exactly. Louie did it. We worked over him nearly all night. Maybe Louie got a little too rough at the last. We were all rather on edge. Anyhow, all at once he heaved up out of the chair where he was tied, and went over sidewise on the floor.

“He seemed to be stunned, but he didn’t come to. We tried everything, but no use. It was getting daylight and we were afraid to wait any longer; so we searched the house without finding anything, and brought him on board here.”

“We expected him to wake up any minute,” Carroll went on, as Floyd stopped. “We watched him day and night. We knew he couldn’t really be hurt. We tried an electric battery—thought he might be shamming. Then we got scared that he was going to die on us. He seemed to be getting weaker; twice we thought he’d passed out. We couldn’t let him die till we found out where he’d planted the stuff. So it looked like a godsend when we heard that you were in Mobile, and read about the great work you’d done on just such cases.”

“Yes, we were at our wits’ end, doctor,” said Floyd. “You mustn’t hold a grudge against us for half kidnaping you. Really it’s a compliment. And you won’t lose anything. If you can help us, and get Rockett to talk, and we find out what he’s done with his loot—why, you can ask for what you like, and get it.”

They fixed intense eyes on the doctor. Lang shrugged his shoulders.

“I can’t revive him, not at this stage anyway,” he said. “I couldn’t if I would, and I wouldn’t try.”

“But we’ve got to make him talk!” cried Carroll. “What’s the chance that he’ll come round?”

“About an even chance, I should think, whether he gradually improves, or gradually sinks and dies without ever regaining consciousness. Of course a moment might come when he could be revived with stimulants—you can’t predict in these cases.”

“But you won’t desert us?” Floyd pleaded. “You’ll see us through?”
