Rokoff’s attitude was so distinctly filled with the threat of physical violence that the ape-man paused for an instant just behind the trio, instinctively sensing an atmosphere of danger. Scarcely had he hesitated ere the man seized the woman roughly by the wrist, twisting it as though to wring a promise from her through torture. What would have happened next had Rokoff had his way we may only conjecture, since he did not have his way at all. Instead, steel fingers gripped his shoulder, and he was swung unceremoniously around, to meet the cold gray eyes of the stranger who had thwarted him on the previous day.

Sapristi!” screamed the infuriated Rokoff. “What do you mean? Are you a fool that you thus again insult Nikolas Rokoff?”

“This is my answer to your note, monsieur,” said Tarzan, in a low voice. And then he hurled the fellow from him with such force that Rokoff lunged sprawling against the rail.

“Name of a name!” shrieked Rokoff. “Pig, but you shall die for this,” and, springing to his feet, he rushed upon Tarzan, tugging the meanwhile to draw a revolver from his hip pocket. The girl shrank back in terror.

“Nikolas!” she cried. “Do not—oh, do not do that. Quick, monsieur, fly, or he will surely kill you!” But instead of flying Tarzan advanced to meet the fellow. “Do not make a fool of yourself, monsieur,” he said.

Rokoff, who was in a perfect frenzy of rage at the humiliation the stranger had put upon him, had at last succeeded in drawing the revolver. He had stopped, and now he deliberately raised it to Tarzan’s breast and pulled the trigger. The hammer fell with a futile click on an empty chamber—the ape-man’s hand shot out like the head of an angry python; there was a quick wrench, and the revolver sailed far out across the ship’s rail, and dropped into the Atlantic.

For a moment the two men stood there facing one another. Rokoff had regained his self-possession. He was the first to speak.

“Twice now has monsieur seen fit to interfere in matters which do not concern him. Twice he has taken it upon himself to humiliate Nikolas Rokoff. The first offense was overlooked on the assumption that monsieur acted through ignorance, but this affair shall not be overlooked. If monsieur does not know who Nikolas Rokoff is, this last piece of effrontery will insure that monsieur later has good reason to remember him.”

“That you are a coward and a scoundrel, monsieur,” replied Tarzan, “is all that I care to know of you,” and he turned to ask the girl if the man had hurt her, but she had disappeared. Then, without even a glance toward Rokoff and his companion, he continued his stroll along the deck.

Tarzan could not but wonder what manner of conspiracy was on foot, or what the scheme of the two men might be. There had been something rather familiar about the appearance of the veiled woman to whose rescue he had just come, but as he had not seen her face he could not be sure that he had ever seen her before. The only thing about her that he had particularly noticed was a ring of peculiar workmanship upon a finger of the hand that Rokoff had seized, and he determined to note the fingers of the women passengers he came upon thereafter, that he might discover the identity of her whom Rokoff was persecuting, and learn if the fellow had offered her further annoyance.
