Just as the two came opposite the figure, Tarzan heard his name whispered in a hoarse voice. He stopped. "Beware of Erot!" whispered the voice. "Tonight!" Then the figure wheeled and lumbered into the denser shadows of the narrow alleyway, but in the glimpse that Tarzan got of it there was a familiar roll to the great body, just as there had been a suggestion of familiarity in the voice.
"Now who do you suppose that is?" demanded Gemnon. "Come on! We'll capture him and find out," and he started as though to pursue the stranger down the alley.
Tarzan laid a restraining hand upon his shoulder.
"No," he said. "It was someone who has tried to befriend me. If he wishes to conceal his identity, it is not for me to reveal it."
"You are right," assented Gemnon.
"And I think I would have learned no more by pursuing him than I already know. I recognized him by his voice and his gait, and then, as he turned to leave, a movement in the air brought his scent spoor to my nostrils.
I think I would recognize that a mile away, for it is very strong; it always is in powerful men and beasts."
"Why was he afraid of you?" asked Gemnon.
"He was not afraid of me; he was afraid of you because you are a noble."
"He need not have been, if he is a friend of yours. I would not have betrayed him."
"I know that, but he could not. You are a noble, and so you might be a friend of Erot. I do not mind telling you who it was, because I know you would not use the knowledge to harm him. But you will be surprised; I surely was. It was Phobeg."
"No! Why should he befriend the man who defeated and humiliated him, and almost killed him?"
"Because he did not kill him. Phobeg is a simple minded fellow, but he is the type that would not be devoid of gratitude. He is the sort that would bestow doglike devotion upon one who was more powerful than he, for he worships physical prowess."
At the palace of Thudos the two men were ushered into a magnificent apartment by a slave, after the guard at the entrance had recognized Gemnon and permitted them to pass. In the soft light of a dozen cressets they awaited the coming of the daughter of the house to whom the slave carried Gemnon's ring to evidence the identity of her caller.
The light fall of soft sandals upon stone announced the ctmine of their hostess, and both men turned toward the doorway leading into a small open garden from which she was coming. Tarzan saw a girl of exquisite beauty; but be was more beautiful than Nemone he could not say, there are so many things that enter into the making of a beautiful countenance. Yet he acknowledged to himself that Thudos was wise in keeping her hidden from the queen. She greeted Gemnon with the sweet familiarty of an Old friend, and when Tarzan was present her manner Was cordial and unaffected, yet always the fact that she Was the daughter of Thudos seemed a part of her.
The three spent the evening in pleasant Conversation, and Gemnon and Tarzan were about to leave, when a middle-aged man entered the room. It was Thudos, the father of Doria. He greeted Gemnon cordially and seemed pleased to meet Tarzan, whom he immediately commenced to question relative to the world outside the valleys of Onthar and Thenar.
Thudos was a strikingly handsome man, with strong features, an athletic build, and eyes that were serious and stern that yet had wrinkles at their corners that betokened much laughter. His was a face that one might trust, for integrity, loyalty, and courage had left their imprints plainly upon it, at least for eyes as observant as those of the Lord of the Jungle.
When the two guests rose to leave again, Thudos seemed satisfied with his appraisal of the stranger. "I am glad that Gemnon brought you," he said. "The very fact that he did convinces me that he has confidence in your friendship and loyalty, for, as you may already know, the position of my house at the court of Nemone is such that we receive only assured friends within our walls."
"I understand," replied the ape-man. He made no other reply, but both Thudos and Doria felt that here was a man who might be trusted.
As the two men entered the avenue in front of the palace of their host, a figure slunk into the shadow of a tree a few paces from them, and neither saw it. Then they walked leisurely toward their apartments in the palace.
"Doria said she saw my meeting with Phobeg in the arena," remarked Tarzan. "I have been curious to ask you how she dared come to the stadium when her life is constantly in danger should her beauty become known to the queen?"
"She is always disguised when she goes abroad," replied Gemnon. "A few touches by an expert hand and hollows appear in her cheeks and beneath her eyes, her brow is wrinkled, and behold! She is no longer the most beautiful woman in the world. Nemone would not give her a second thought if she saw her, but still care is taken to see that Nemone does not see her too closely even then. It is informers we fear the most. Thudos never sells a slave who has seen Doria, and once a new slave enters the palace walls he never leaves them again until long years of service have proved him, and his loyalty is unquestioned. "It is a monotonous life for Doria, the penalty she pays for beauty, but all that we can do is hope and pray that relief will come some day in the death of Nemone or the elevation of Alextar to the throne."
Valthor was asleep on Tarzan's couch when the ape-man entered his bedroom. He had had little rest since his capture, and, in addition, he was suffering from a cliaht wound, so Tarzan moved softly that he might not disturb him and made no light in the room, the darkness of which was partially dispelled by moonlight.
Spreading some skins on the floor against the wall opposite the window, the ape-man lay down and was soon asleep, while in the apartment above him two men crouched in the dark beside the window that was directly above that in Tarzan's bedroom.
For a long time they crouched there in silence. One a large, powerful man, the other smaller and lighter.
Fully an hour passed before either moved other than to Changed a cramped position for one more comfortable; Then smaller man arose. One end of a long rope was Knotted about his body beneath beneath his armpits; in his right He carried a slim dagger-sword.
Cautiously, and silently he went to the window and Looked out, his careful gaze searching the grounds below; Then he sat on the sill and swung his legs through the Window. The larger man, holding the rope firmly with both hands, braced himself. The smaller turned over on his belly and slid out of the window. Hand over hand, the other lowered him; his head dissapeared below the sill.
Very carefully, so as to make no noise, the larger man lowered the smaller until the feet of the latter rested on the sill of Tarzan's bedroom window. Here the man reached in and took hold of the casing; then he jerked twice upon the rope to acquaint his fellow with the fact that he had reached his destination safely and the other let the rope slip through his fingers loosely as the movements of the man below dragged it slowly out.
The smaller man stepped gingerly to the floor inside the room. Without hesitation he moved toward the bed, his weapon raised and ready in his hand. He made no haste; his one purpose for the present appeared to be the achievement of absolute silence. It was evident that he feared to waken the sleeper. Even when he reached the bed he stood there for a long time searching with his eyes for the right spot to strike that the blow might bring instant death. The assassin knew that Gemnon slept in another bedroom across the living room; what he did not know was that Valthor, the Athnean, lay stretched on the bed beneath his keen weapon.
