To their knock a woman’s voice asked in French: “Who is it?”

“It is I, Olga—Nikolas,” was the answer, in Rokoff’s now familiar guttural. “May I come in?”

“Why do you not cease persecuting me, Nikolas?” came the voice of the woman from beyond the thin panel. “I have never harmed you.”

“Come, come, Olga,” urged the man, in propitiary tones; “I but ask a half dozen words with you. I shall not harm you, nor shall I enter your cabin; but I cannot shout my message through the door.”

Tarzan heard the catch click as it was released from the inside. He stepped out from his hiding-place far enough to see what transpired when the door was opened, for he could not but recall the sinister words he had heard a few moments before upon the deck, “And if she screams you may choke her.”

Rokoff was standing directly in front of the door. Paulvitch had flattened himself against the paneled wall of the corridor beyond. The door opened. Rokoff half entered the room, and stood with his back against the door, speaking in a low whisper to the woman, whom Tarzan could not see. Then Tarzan heard the woman’s voice, level, but loud enough to distinguish her words.

“No, Nikolas,” she was saying, “it is useless. Threaten as you will, I shall never accede to your demands. Leave the room, please; you have no right here. You promised not to enter.”

“Very well, Olga, I shall not enter; but before I am done with you, you shall wish a thousand times that you had done at once the favor I have asked. In the end I shall win anyway, so you might as well save trouble and time for me, and disgrace for yourself and your—”

“Never, Nikolas!” interrupted the woman, and then Tarzan saw Rokoff turn and nod to Paulvitch, who sprang quickly toward the doorway of the cabin, rushing in past Rokoff, who held the door open for him. Then the latter stepped quickly out. The door closed. Tarzan heard the click of the lock as Paulvitch turned it from the inside. Rokoff remained standing before the door, with head bent, as though to catch the words of the two within. A nasty smile curled his bearded lip.

Tarzan could hear the woman’s voice commanding the fellow to leave her cabin. “I shall send for my husband,” she cried. “He will show you no mercy.”
