"We were about to have coffee and we should be delighted to have you join us. We meant no wrong in coming here, and I can assure you that we will gladly and willingly make full amends to you, or to whomever else we may have unintentionally wronged."

To take coffee with these men would do no harm. Perhaps he had wronged them, but however that might be a cup of their coffee would place no great obligation upon him. Flora had been right in her assertion that if Tarzan of the Apes had any weakness whatsoever it was for an occasional cup of black coffee late at night. He did not accept the proffered camp stool, but squatted, ape-fashion, before them, the flickering light of the beast fires playing upon his bronzed hide and bringing into relief the gracefully contoured muscles of his godlike frame. Not as the muscles of the blacksmith or the professional strong man were the muscles of Tarzan of the Apes, but rather those of Mercury or Apollo, so symmetrically balanced were their proportions, suggesting only the great strength that lay in them. Trained to speed and agility were they as well as to strength, and thus, clothing as they did his giant frame, they imparted to him the appearance of a demi-god.

Throck, Peebles, and Bluber sat watching him in spellbound fascination, while Kraski walked over to the cook fire to arrange for the coffee. The two Englishmen were as yet only half awakened to the fact that they had mistaken this newcomer for another, and as it was, Peebles still scratched his head and grumbled to himself in inarticulate half-denial of Kraski's assumption of the new identity of Tarzan. Bluber was inwardly terror-stricken. His keener intelligence had quickly grasped the truth of Kraski's recognition of the man for what he was rather than for what Peebles and Throck thought him to be, and, as Bluber knew nothing of Flora's plan, he was in quite a state of funk as he tried to visualize the outcome of Tarzan's discovery of them at the very threshold of Opar. He did not realize, as did Flora, that their very lives were in danger--that it was Tarzan of the Apes, a beast of the jungle, with whom they had to deal, and not John Clayton, Lord Greystoke, an English peer. Rather was Bluber considering the two thousand pounds that they stood to lose through this deplorable termination of their expedition, for he was sufficiently familiar with the reputation of the ape-man to know that they would never be permitted to take with them the gold that Esteban was very likely, at this moment, pilfering from the vaults of Opar. Really Bluber was almost upon the verge of tears when Kraski returned with the coffee, which he brought himself.

From the dark shadows of the tent's interior Flora Hawkes looked nervously out upon the scene before her. She was terrified at the possibility of discovery by her former employer, for she had been a maid in the Greystokes' London town house as well as at the African bungalow and knew that Lord Greystoke would recognize her instantly should he chance to see her. She entertained for him, now, in his jungle haunts, a fear that was possibly greater than Tarzan's true character warranted, but none the less real was it to the girl whose guilty conscience conjured all sorts of possible punishments for her disloyalty to those who had always treated her with uniform kindliness and consideration.

Constant dreaming of the fabulous wealth of the treasure vaults of Opar, concerning which she had heard so much in detail from the conversations of the Greystokes, had aroused within her naturally crafty and unscrupulous mind a desire for possession, and in consequence thereof she had slowly visualized a scheme whereby she might loot the treasure vaults of a sufficient number of the golden ingots to make her independently wealthy for life. The entire plan had been hers. She had at first interested Kraski, who had in turn enlisted the cooperation of the two Englishmen and Bluber, and these four had raised the necessary money to defray the cost of the expedition. It had been Flora who had searched for a type of man who might successfully impersonate Tarzan in his own jungle, and she had found Esteban Miranda, a handsome, powerful, and unscrupulous Spaniard, whose histrionic ability aided by the art of make-up, of which he was a past master, permitted him to almost faultlessly impersonate the character they desired him to portray, in so far, as least, as outward appearances were concerned.

The Spaniard was not only powerful and active, but physically courageous as well, and since he had shaved his beard and donned the jungle habiliments of a Tarzan, he had lost no opportunity for emulating the ape-man in every way that lay within his ability. Of jungle craft he had none of course, and personal combats with the more savage jungle beasts caution prompted him to eschew, but he hunted the lesser game with spear and with arrow and practiced continually with the grass rope that was a part of his make-up.

And now Flora Hawkes saw all her well-laid plans upon the verge of destruction. She trembled as she watched the men before the fire, for her fear of Tarzan was very real, and then she became tense with nervous anticipation as she saw Kraski approaching the group with the coffee pot in one hand and cups in the other. Kraski set the pot and the cups upon the ground a little in the rear of Tarzan, and, as he filled the latter, she saw him pour a portion of the contents of the bottle she had given him into one of the cups. A cold sweat broke out upon her forehead as Kraski lifted this cup and offered it to the ape-man. Would he take it? Would he suspect? If he did suspect what horrible punishment would be meted to them all for their temerity? She saw Kraski hand another cup to Peebles, Throck, and Bluber, then return to the circle with the last one for himself. As the Russian raised it before his face and bowed politely to the ape-man, she saw the five men drink. The reaction which ensued left her weak and spent. Turning she collapsed upon her cot, and lay there trembling, her face buried in her arm. And, outside, Tarzan of the Apes drained his cup to the last drop.

Chapter VI. DEATH STEALS BEHIND

During the afternoon of the day that Tarzan discovered the camp of the conspirators, a watcher upon the crumbling outer wall of the ruined city of Opar descried a party of men moving downward into the valley from the summit of the encircling cliff. Tarzan, Jane Clayton, and their black Waziri were the only strangers that the denizens of Opar had ever seen within their valley during the lifetime of the oldest among them, and only in half-forgotten legends of a by-gone past was there any suggestion that strangers other than these had ever visited Opar. Yet from time immemorial a guard had always remained upon the summit of the outer wall.
