of native soldiers by Tarzan and Numa, the lion, upon that memorable night that the ape-man had loosed a famishing man-eater among the superstitious and terror-stricken blacks. The Second Rhodesian Regiment had immediately taken possession of the abandoned trench and from this position their flanking fire had raked contiguous sections of the German line, the diversion rendering possible a successful night attack on the part of the balance of the British forces.
Weeks had elapsed. The Germans were contesting stubbornly every mile of waterless, thorn-covered ground and clinging desperately to their positions along the railway. The officers of the Second Rhodesians had seen nothing more of Tarzan of the Apes since he had slain Underlieutenant von Goss and disappeared toward the very heart of the German position, and there were those among them who believed that he had been killed within the enemy lines.
"They may have killed him," assented Colonel Capell; "but I fancy they never captured the beggar alive."
Nor had they, nor killed him either. Tarzan had spent those intervening weeks pleasantly and profitably. He had amassed a considerable fund of knowledge concerning the disposition and strength of German troops, their methods of warfare, and the various ways in which a lone Tarmangani might annoy an army and lower its morale.
At present he was prompted by a specific desire. There was a certain German spy whom he wished to capture alive and take back to the British. When he had made his first visit to German headquarters, he had seen a young woman deliver a paper to the German general, and later he had seen that same young woman within the British lines in the uniform of a British officer. The conclusions were obvious—she was a spy.
And so Tarzan haunted German headquarters upon many nights hoping to see her again or to pick up some clew as to her whereabouts, and at the same time he utilized many an artifice whereby he might bring terror to the hearts of the Germans. That he was successful was often demonstrated by the snatches of conversation he overheard as he prowled through the German camps. One night as he lay concealed in the bushes close beside a regimental headquarters he listened to the conversation of several Boche officers. One of the men reverted to the stories told by the native troops in connection with their rout by a lion several weeks before and the simultaneous appearance in their trenches of a naked, white giant whom they were perfectly assured was some demon of the jungle.
"The fellow must have been the same as he who leaped into the general's headquarters and carried off Schneider," asserted one. "I wonder how he happened to single out the poor major. They say the creature seemed interested in no one but Schneider. He had von Kelter in his grasp, and he might easily have taken the general himself; but he ignored them all except Schneider. Him he pursued about the room, seized and carried off into the night. Gott knows what his fate was."
"Captain Fritz Schneider has some sort of theory," said another. "He told me only a week or two ago that he thinks he knows why his brother was taken—that it was a case of mistaken identity. He was not so sure about it until von Goss was killed, apparently by the same creature, the night the lion entered the trenches. Von Goss was attached to Schneider's company. One of Schneider's men was found with his neck wrung the same night that the major was carried off and Schneider thinks that this devil is after him and his command—that it came for him that night and got his brother by mistake. He says Kraut told him that in presenting the major to Fräulein Kircher the former's name was no sooner spoken than this wild man leaped through the window and made for him."
Suddenly the little group became rigid—listening. "What was that?" snapped one, eyeing the bushes from which a smothered snarl had issued as Tarzan of the Apes realized that through his mistake the perpetrator of the horrid crime at his bungalow still lived—that the murderer of his wife went yet unpunished.
For a long minute the officers stood with tensed nerves, every eye riveted upon the bushes from whence the ominous sound had issued. Each recalled recent mysterious disappearances from the heart of camps as well as from lonely out-guards. Each thought of the silent dead he had seen, slain almost within sight of their fellows by some unseen creature. They thought of the marks upon dead throats—made by talons or by giant fingers, they could not tell which—and those upon shoulders and jugulars where powerful teeth had fastened and they waited with drawn pistols.
Once the bushes moved almost imperceptibly and an instant later one of the officers, without warning, fired into them; but Tarzan of the Apes was not there. In the interval between the moving of the bushes and the firing of the shot he had melted into the night. Ten minutes later he was hovering on the outskirts of that part of camp where were bivouacked for the night the black soldiers of a native company commanded by one Hauptmann Fritz Schneider. The men were stretched upon the ground without tents; but there were tents pitched for the officers. Toward these Tarzan crept. It was slow and perilous work, as the Germans were now upon the alert for the uncanny foe that crept into their camps to take his toll by night, yet the ape-man passed their sentinels, eluded the vigilance of the interior guard, and crept at last to the rear of the officers' line.
Here he flattened himself against the ground close behind the nearest tent and listened. From within came the regular breathing of a sleeping man—one only. Tarzan was satisfied. With his knife he cut the tie strings of the rear flap and entered. He made no noise. The shadow of a falling leaf, floating gently to earth upon a still day, could have been no more soundless. He moved to the side of the sleeping man and bent low over him. He could not know, of course, whether it was Schneider or another, as he had never seen Schneider; but he meant to know and to know even more. Gently he shook the man by the shoulder. The fellow turned heavily and grunted in a thick guttural.
"Silence!" admonished the ape-man in a low whisper. "Silence—I kill."
The Hun opened his eyes. In the dim light he saw a giant figure bending over him. Now a mighty hand grasped his shoulder and another closed lightly about his throat.
"Make no outcry," commanded Tarzan; "but answer in a whisper my questions. What is your name?"
"Luberg," replied the officer. He was trembling. The weird presence of this naked giant filled him with dread. He, too, recalled the men mysteriously murdered in the still watches of the night camps. "What do you want?"
"Where is Hauptmann Fritz Schneider?" asked Tarzan, "Which is his tent?"
"He is not here," replied Luberg. "He was sent to Wilhelmstal yesterday."
"I shall not kill you—now," said the ape-man. "First I shall go and learn if you have lied to me and if you have your death shall be the more terrible. Do you know how Major Schneider died?"
Luberg shook his head negatively.
"I do," continued Tarzan, "and it was not a nice way to die—even for an accursed German. Turn over with your face down and cover your eyes. Do not move or make any sound."
The man did as he was bid and the instant that his eyes were turned away, Tarzan slipped from the tent. An hour later he was outside the German camp and headed for the little hill town of Wilhelmstal, the summer seat of government of German East Africa.
Fräulein Bertha Kircher was lost. She was humiliated and angry—it was long before she would admit it, that she, who prided herself upon her woodcraft, was lost in this little patch of country between the Pangani and the Tanga railway. She knew that Wilhelmstal lay southeast of her about fifty miles; but, through a combination of untoward circumstances, she found herself unable to determine which was southeast.
In the first place she had set out from German headquarters on a well-marked road that was being traveled by troops and with every reason to believe that she would follow that road to Wilhelmstal. Later she had been warned from this road by word that a strong British patrol had come down the west bank
