blank at the fiend's face.
Simultaneously there broke upon the astonished ears of both attackers and attacked a volley of shots from the gorge. With the sweetness of the voice of an angel from heaven the Europeans heard the sharp-barked commands of an English noncom. Even above the roars of the lions and the screams of the maniacs, those beloved tones reached the ears of Tarzan and the girl at the very moment that even the ape-man had given up the last vestige of hope.
Rolling the body of the warrior to one side Tarzan struggled to his feet, the spear still protruding from his shoulder. The girl rose too, and as Tarzan wrenched the weapon from his flesh and stepped out from behind the concealment of their refuge, she followed at his side. The skirmish that had resulted in their rescue was soon over. Most of the lions escaped but all of the pursuing Xujans had been slain. As Tarzan and the girl came into full view of the group, a British Tommy leveled his rifle at the ape-man. Seeing the fellow's actions and realizing instantly the natural error that Tarzan's yellow tunic had occasioned the girl sprang between him and the soldier. 'Don't shoot,' she cried to the latter, 'we are both friends.'
'Hold up your hands, you, then,' he commanded Tarzan. 'I ain't taking no chances with any duffer with a yellow shirt.'
At this juncture the British sergeant who had been in command of the advance guard approached and when Tarzan and the girl spoke to him in English, explaining their disguises, he accepted their word, since they were evidently not of the same race as the creatures which lay dead about them. Ten minutes later the main body of the expedition came into view. Smith-Oldwick's wounds were dressed, as well as were those of the ape-man, and in half an hour they were on their way to the camp of their rescuers.
That night it was arranged that the following day Smith-Oldwick and Bertha Kircher should be transported to British headquarters near the coast by aeroplane, the two planes attached to the expeditionary force being requisitioned for the purpose. Tarzan and Otobu declined the offers of the British captain to accompany his force overland on the return march as Tarzan explained that his country lay to the west, as did Otobu's, and that they would travel together as far as the country of the Wamabos.
'You are not going back with us, then?' asked the girl.
'No,' replied the ape-man. 'My home is upon the west coast. I will continue my journey in that direction.'
She cast appealing eyes toward him. 'You will go back into that terrible jungle?' she asked. 'We shall never see you again?'
He looked at her a moment in silence. 'Never,' he said, and without another word turned and walked away.
In the morning Colonel Capell came from the base camp in one of the planes that was to carry Smith-Oldwick and the girl to the east. Tarzan was standing some distance away as the ship landed and the officer descended to the ground. He saw the colonel greet his junior in command of the advance detachment, and then he saw him turn toward Bertha Kircher who was standing a few paces behind the captain. Tarzan wondered how the German spy felt in this situation, especially when she must know that there was one there who knew her real status. He saw Colonel Capell walk toward her with outstretched hands and smiling face and, although he could not hear the words of his greeting, he saw that it was friendly and cordial to a degree.
Tarzan turned away scowling, and if any had been close by they might have heard a low growl rumble from his chest. He knew that his country was at war with Germany and that not only his duty to the land of his fathers, but also his personal grievance against the enemy people and his hatred of them, demanded that he expose the girl's perfidy, and yet he hesitated, and because he hesitated he growled—not at the German spy but at himself for his weakness.
He did not see her again before she entered a plane and was borne away toward the east. He bid farewell to Smith-Oldwick and received again the oft-repeated thanks of the young Englishman. And then he saw him too borne aloft in the high circling plane and watched until the ship became a speck far above the eastern horizon to disappear at last high in air.
The Tommies, their packs and accouterments slung, were waiting the summons to continue their return march. Colonel Capell had, through a desire to personally observe the stretch of country between the camp of the advance detachment and the base, decided to march back his troops. Now that all was in readiness for departure he turned to Tarzan. 'I wish you would come back with us, Greystoke,' he said, 'and if my appeal carries no inducement possibly that of Smith-Oldwick 'and the young lady who just left us may. They asked me to urge you to return to civilization.'
'No;' said Tarzan, 'I shall go my own way. Miss Kircher and Lieutenant Smith-Oldwick were only prompted by a sense of gratitude in considering my welfare.'
'Miss Kircher?' exclaimed Capell and then he laughed, 'You know her then as Bertha Kircher, the German spy?'
Tarzan looked at the other a moment in silence. It was beyond him to conceive that a British officer should thus laconically speak of an enemy spy whom he had had within his power and permitted to escape. 'Yes,' he replied, 'I knew that she was Bertha Kircher, the German spy?'
'Is that all you knew?' asked Capell.
'That is all,' said the ape-man.
'She is the Honorable Patricia Canby,' said Capell, 'one of the most valuable members of the British Intelligence Service attached to the East African forces. Her father and I served in India together and I have known her ever since she was born.
'Why, here's a packet of papers she took from a German officer and has been carrying it through all her vicissitudes-single-minded in the performance of her duty. Look! I haven't yet had time to examine them but as you see here is a military sketch map, a bundle of reports, and the diary of one Hauptmann Fritz Schneider.'
'The diary of Hauptmann Fritz Schneider!' repeated Tarzan in a constrained voice. 'May I see it, Capell? He is the man who murdered Lady Greystoke.'
The Englishman handed the little volume over to the other without a word. Tarzan ran through the pages quickly looking for a certain date—the date that the horror had been committed—and when he found it he read rapidly. Suddenly a gasp of incredulity burst from his lips. Capell looked at him questioningly.
'God!' exclaimed the ape-man. 'Can this be true? Listen!' and he read an excerpt from the closely written page:
''Played a little joke on the English pig. When he comes home he will find the burned body of his wife in her boudoir-but he will only think it is his wife. Had von Goss substitute the body of a dead Negress and char it after putting Lady Greystoke's rings on it—Lady G will be of more value to the High Command alive than dead.''
'She lives!' cried Tarzan.
'Thank God!' exclaimed Capell. 'And now?'
'I will return with you, of course. How terribly I have wronged Miss Canby, but how could I know? I even told Smith-Oldwick, who loves her, that she was a German spy.
'Not only must I return to find my wife but I must right this wrong.'
'Don't worry about that,' said Capell, 'she must have convinced him that she is no enemy spy, for just before they left this morning he told me she had promised to marry him.'
