"Tell him," said Tarzan, "to hold his peace or I will slay him."
Otobu did as he was instructed and the young maniac lapsed into scowling silence. Tarzan crossed the alcove and entered the outer room to note the effect of the assaults upon the door. Smith-Oldwick followed him a few steps, leaving Otobu to guard the two prisoners. The ape-man saw that the door could not long withstand the heavy blows being dealt the panels from without. "I wanted to use that fellow in the other room," he said to Smith-Oldwick, "but I am afraid we will have to get out of here the way we came. We can't accomplish anything by waiting here and meeting these fellows. From the noise out there there must be a dozen of them. Come," he said, "you go first and I will follow."
As the two turned back from the alcove they witnessed an entirely different scene from that upon which they had turned their backs but a moment or two before. Stretched on the floor and apparently lifeless lay the body of the black slave while the two prisoners had vanished completely.
