The black man had now removed the outer garments from the dead man, and Smith-Oldwick was hastily drawing them on over his own clothing. "And now," said Tarzan, "we will sit down and eat. One accomplishes little on an empty stomach." As they ate the ape-man attempted to carry on a conversation with the two natives through Otobu. He learned that they were in the palace which had belonged to the dead man lying upon the floor beside them. He had held an official position of some nature, and he and his family were of the ruling class but were not members of the court.
When Tarzan questioned them about Bertha Kircher, the young man said that she had been taken to the king's palace; and when asked why replied: "For the king, of course."
During the conversation both the man and the girl appeared quite rational, even asking some questions as to the country from which their uninvited guests had come, and evidencing much surprise when informed that there was anything but waterless wastes beyond their own valley.
When Otobu asked the man, at Tarzan's suggestion, if he was familiar with the interior of the king's palace, he replied that he was; that he was a friend of Prince Metak, one of the king's sons, and that he often visited the palace and that Metak also came here to his father's palace frequently. As Tarzan ate he racked his brain for some plan whereby he might utilize the knowledge of the young man to gain entrance to the palace, but he had arrived at nothing which he considered feasible when there came a loud knocking upon the door of the outer room.
For a moment no one spoke and then the young man raised his voice and cried aloud to those without. Immediately Otobu sprang for the fellow and attempted to smother his words by clapping a palm over his mouth.
"What is he saying?" asked Tarzan.
"He is telling them to break down the door and rescue him and the girl from two strangers who entered and made them prisoners. If they enter they will kill us all."
"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.
