"She has been carried away" was the startling answer. "Your creatures, under the thing you wished to marry her to, have taken her to Borneo with a band of Malay and Dyak pirates. I was alone and could do nothing to prevent them."
"God!" moaned the old man. "Why did I not kill the thing when it stood within my power to do so. Only last night he was here beside me, and now it is too late."
"I warned you," said von Horn, coldly.
"I was mad," retorted the professor. "Could you not see that I was mad? Oh, why did you not stop me? You were sane enough. You at least might have forced me to abandon the insane obsession which has overpowered my reason for all these terrible months. I am sane now, but it is too late—too late."
"Both you and your daughter could only have interpreted any such action on my part as instigated by self-interest, for you both knew that I wanted to make her my wife," replied the other. "My hands were tied. I am sorry now that I did not act, but you can readily see the position in which I was placed."
"Can nothing be done to get her back?" cried the father. "There must be some way to save her. Do it von Horn, and not only is my daughter yours but my wealth as well—every thing that I possess shall be yours if you will but save her from those frightful creatures."
"The Ithaca is gone, too," replied the doctor. "There is only a small boat that I hid in the jungle for some such emergency. It will carry us to Borneo , but what can we four do against five hundred pirates and the dozen monsters you have brought into the world? No, Professor Maxon, I fear there is little hope, though I am willing to give my life in an attempt to save Virginia . You will not forget your promise should we succeed?"
"No, doctor," replied the old man. "I swear that you shall have Virginia as your wife, and all my property shall be made over to you if she is rescued."
Sing Lee had been a silent listener to this strange conversation. An odd look came into his slant eyes as he heard von Horn exact a confirmation from the professor, but what passed in his shrewd mind only he could say.
It was too late to attempt to make a start that day for Borneo , as darkness had already fallen. Professor Maxon and von Horn walked over to the workshop and the inner campong to ascertain what damage had been done there.
On their return Sing was setting the table on the verandah for the evening meal. The two men were talking, and without making his presence noticeable the Chinaman hovered about ever within ear shot.
"I cannot make it out, von Horn," Professor Maxon was saying. "Not a board broken, and the doors both apparently opened intentionally by someone familiar with locks and bolts. Who could have done it?"
"You forget Number Thirteen," suggested the doctor.
"But the chest!" expostulated the other. "What in the world would he want of that enormous and heavy chest?"
"He might have thought that it contained treasure," hazarded von Horn, in an innocent tone of voice.
"Bosh, my dear man," replied Professor Maxon. "He knew nothing of treasures, or money, or the need or value of either. I tell you the workshop was opened, and the inner campong as well by some one who knew the value of money and wanted that chest, but why they should have released the creatures from the inner enclosure is beyond me."
"And I tell you Professor Maxon that it could have been none other than Number Thirteen," insisted von Horn. "Did I not myself see him leading his eleven monsters as easily as a captain commands his company? The fellow is brighter than we have imagined. He has learned much from us both, he has reasoned, and he has shrewdly guessed many things that he could not have known through experience."
"But his object?" asked the professor.
"That is simple," returned von Horn. "You have held out hopes to him that soon he should come to live under your roof with Virginia . The creature has been madly infatuated with her ever since the day he took her from Number One, and you have encouraged his infatuation until yesterday. Then you regained your sanity and put him in his rightful place. What is the result? Denied the easy prey he expected he immediately decided to take it by force, and with that end in view, and taking advantage of the series of remarkable circumstances which played into his hands, he liberated his fellows, and with them hastened to the beach in search of Virginia and in hopes of being able to fly with her upon the Ithaca. There he met the Malay pirates, and together they formed an alliance under terms of which Number Thirteen is to have the girl, and the pirates the chest in return for transporting him and his crew to Borneo . Why it is all perfectly simple and logical, Professor Maxon; do you not see it now?"
"You may be right, doctor," answered the old man. "But it is idle to conjecture. Tomorrow we can be up and doing, so let us get what sleep we can tonight. We shall need all our energies if we are to save my poor, dear girl, from the clutches of that horrid, soulless thing."
At the very moment that he spoke the object of his contumely was entering the dark mouth of a broad river that flowed from out of the heart of savage Borneo . In the prahu with him his eleven hideous companions now bent to their paddles with slightly increased efficiency. Before them the leader saw a fire blazing upon a tiny island in the center of the stream. Toward this they turned their silent way. Grimly the war prahu with its frightful freight nosed closer to the bank.
At last Number Thirteen made out the figures of men about the fire, and as they came still closer he was sure that they were members of the very party he had been pursuing across the broad waters for hours. The prahus were drawn up upon the bank and the warriors were preparing to eat.
Just as the young giants' prahu came within the circle of firelight a swarthy Malay approached the fire, dragging a white girl roughly by the arm. No more was needed to convince Number Thirteen of the identity of the party. With a low command to his fellows he urged them to redoubled speed. At the same instant a Dyak warrior caught sight of the approaching boat as it sped into the full glare of the light.
At sight of the occupants the head hunters scattered for their own prahus. The frightful aspect of the enemy turned their savage hearts to water, leaving no fight in their ordinarily warlike souls.
So quickly they moved that as the pursuing prahu touched the bank all the nearer boats had been launched, and the remaining pirates were scurrying across the little island for those which lay upon the opposite side. Among these was the Malay who guarded the girl, but he had not been quick enough to prevent Virginia Maxon recognizing the stalwart figure standing in the bow of the oncoming craft.
As he dragged her away toward the prahu of Muda Saffir she cried out to the strange white man who seemed her self-appointed protector.
"Help! Help!" she called. "This way! Across the island!" And then the brown hand of her jailer closed over her mouth. Like a tigress she fought to free herself, or to detain her captor until the rescue party should catch up with them, but the scoundrel was muscled like a bull, and when the girl held back he lifted her across his shoulder and broke into a run.
Rajah Muda Saffir had no stomach for a fight himself, but he was loathe to lose the prize he had but just won, and seeing that his men were panic-stricken he saw no alternative but to rally them for a brief stand that would give the little moment required to slip away in his own prahu with the girl.
Calling aloud for those around him to come to his support he halted fifty yards from his boat just as Number Thirteen with his fierce, brainless horde swept up from the opposite side of the island in the wake of him who bore Virginia Maxon. The old rajah succeeded in gathering some fifty warriors about him from the crews of the two boats which lay near his. His own men he hastened to their posts in his prahu that they might be ready to pull swiftly away the moment that he and the captive were aboard.
