Others then must have escaped from the campong. Von Horn loosened his guns in their holsters, and took a fresh grip upon his bull whip as he urged Sing forward upon the trail. He wondered which one it was, but not once did it occur to him that the latest result of Professor Maxon’s experiments could be the rescuer of Virginia Maxon. In his mind he could see only the repulsive features of one of the others.
Quite unexpectedly they came upon the two, and with a shout von Horn leaped forward, his bull whip upraised. Number Thirteen turned in surprise at the cry, and sensing a new danger for her who lay in his arms, he set her gently upon the ground behind him and advanced to meet his assailant.
“Out of the way, you—monstrosity,” cried von Horn. “If you have harmed Miss Maxon I’ll put a bullet in your heart!”
Number Thirteen did not understand the words that the other addressed to him but he interpreted the man’s actions as menacing, not to himself, but to the creature he now considered his particular charge; and so he met the advancing man, more to keep him from the girl than to offer him bodily injury for he recognized him as one of the two who had greeted his first dawning consciousness.
Von Horn, possibly intentionally, misinterpreted the other’s motive, and raising his bull whip struck Number Thirteen a vicious cut across the face, at the same time levelling his revolver point blank at the broad breast. But before ever he could pull the trigger an avalanche of muscle was upon him, and he went down to the rotting vegetation of the jungle with five sinewy fingers at his throat.
His revolver exploded harmlessly in the air, and then another hand wrenched it from him and hurled it far into the underbrush. Number Thirteen knew nothing of the danger of firearms, but the noise had startled him and his experience with the stinging cut of the bull whip convinced him that this other was some sort of instrument of torture of which it would be as well to deprive his antagonist.
Virginia Maxon looked on in horror as she realized that her rescuer was quickly choking Dr. von Horn to death. With a little cry she sprang to her feet and ran toward them, just as her father emerged from the underbrush through which he had been struggling in the trail of the agile Chinaman and von Horn. Placing her hand upon the great wrist of the giant she tried to drag his fingers from von Horn’s throat, pleading meanwhile with both voice and eyes for the life of the man she thought loved her.
Again Number Thirteen translated the intent without understanding the words, and releasing von Horn permitted him to rise. With a bound he was upon his feet and at the same instant brought his other gun from his side and levelled it upon the man who had released him; but as his finger tightened upon the trigger Virginia Maxon sprang between them and grasping von Horn’s wrist deflected the muzzle of the gun just as the cartridge exploded. Simultaneously Professor Maxon sprang from his grasp and hurled him back with the superhuman strength of a maniac.
“Fool!” he cried. “What would you do? Kill—,” and then of a sudden he realized his daughter’s presence and the necessity for keeping the origin of the young giant from her knowledge.
“I am surprised at you, Dr. von Horn,” he continued in a more level voice. “You must indeed have forgotten yourself to thus attack a stranger upon our island until you know whether he be friend or foe. Come! Escort my daughter to the camp, while I make the proper apologies to this gentleman.” As he saw that both Virginia and von Horn hesitated, he repeated his command in a peremptory tone, adding; “Quick, now; do as I bid you.”
