"There," remarked Tarzan. "Now, lead me to the place you speak of."
Smith-Oldwick had no difficulty in locating the trap in the roof through which he had escaped. Removing the cover the ape-man bent low, listening and sniffing. "Come," he said after a moment's investigation and lowered himself to the floor beneath. Smith-Oldwick followed him, and together the two crept through the darkness toward the door in the back wall of the niche in which the Englishman had been hidden by the girl. They found the door ajar and opening it Tarzan saw a streak of light showing through the hangings that separated it from the alcove.
Placing his eye close to the aperture he saw the girl and the young man of which the Englishman had spoken seated on opposite sides of a low table upon which food was spread. Serving them was a giant Negro and it was he whom the ape-man watched most closely. Familiar with the tribal idiosyncrasies of a great number of African tribes over a considerable proportion of the Dark Continent, the Tarmangani at last felt reasonably assured that he knew from what part of Africa this slave had come, and the dialect of his people. There was, however, the chance that the fellow had been captured in childhood and that through long years of non-use his native language had become lost to him, but then there always had been an element of chance connected with nearly every event of Tarzan's life, so he waited patiently until in the performance of his duties the black man approached a little table which stood near the niche in which Tarzan and the Englishman hid.
As the slave bent over some dish which stood upon the table his ear was not far from the aperture through which Tarzan looked. Apparently from a solid wall, for the Negro had no knowledge of the existence of the niche, came to him in the tongue of his own people, the whispered words: "If you would return to the land of the Wamabo say nothing, but do as I bid you."
The black rolled terrified eyes toward the hangings at his side. The ape-man could see him tremble and for a moment was fearful that in his terror he would betray them. "Fear not," he whispered, "we are your friends."
At last the Negro spoke in a low whisper, scarcely audible even to the keen ears of the ape-man. "What," he asked, "can poor Otobu do for the god who speaks to him out of the solid wall?"
"This," replied Tarzan. "Two of us are coming into this room. Help us prevent this man and woman from escaping or raising an outcry that will bring others to their aid."
"I will help you," replied the Negro, "to keep them within this room, but do not fear that their outcries will bring others. These walls are built so that no sound may pass through, and even if it did what difference would it make in this village which is constantly filled with the screams of its mad people. Do not fear their cries. No one will notice them. I go to do your bidding."
Tarzan saw the black cross the room to the table upon which he placed another dish of food before the feasters. Then he stepped to a place behind the man and as he did so raised his eyes to the point in the wall from which the ape-man's voice had come to him, as much as to say, "Master, I am ready."
Without more delay Tarzan threw aside the hangings and stepped into the room. As he did so the young man rose from the table to be instantly seized from behind by the black slave. The girl, whose back was toward the ape-man and his companion, was not at first aware of their presence but saw only the attack of the slave upon her lover, and with a loud scream she leaped forward to assist the latter. Tarzan sprang to her side and laid a heavy hand upon her arm before she could interfere with Otobu's attentions to the young man. At first, as she turned toward the ape-man, her face reflected only mad rage, but almost instantly this changed into the vapid smile with which Smith-Oldwick was already familiar and her slim fingers commenced their soft appraisement of the newcomer.
