There was no sound as the man beast sprang upon the back of his prey and bore it to the ground for steel fingers closed simultaneously upon the soldier's throat, effectually stifling any outcry. By the neck Tarzan dragged his victim well into the concealment of the bushes.

"Make no sound," he cautioned in the man's own tribal dialect as he released his hold upon the other's throat.

The fellow gasped for breath, rolling frightened eyes upward to see what manner of creature it might be in whose power he was. In the darkness he saw only a naked brown body bending above him; but he still remembered the terrific strength of the mighty muscles that had closed upon his wind and dragged him into the bushes as though he had been but a little child. If any thought of resistance had crossed his mind he must have discarded it at once, as he made no move to escape.

"What is the name of the officer who killed the woman at the bungalow where you fought with the Waziri?" asked Tarzan.

"Hauptmann Schneider," replied the black when he could again command his voice.

"Where is he?" demanded the ape-man.

"He is here. It may be that he is at headquarters. Many of the officers go there in the evening to receive orders."

"Lead me there," commanded Tarzan, "and if I am discovered I will kill you immediately. Get up!"

The black rose and led the way by a roundabout route back through the camp. Several times they were forced to hide while soldiers passed; but at last they reached a great pile of baled hay from about the corner of which the black pointed out a two-story building in the distance.

"Headquarters," he said. "You can go no farther unseen. There are many soldiers about."

Tarzan realized that he could not proceed farther in company with the black. He turned and looked at the fellow for a moment as though pondering what disposition to make of him.

"You helped to crucify Wasimbu, the Waziri," he accused in a low yet none the less terrible tone.

The black trembled, his knees giving beneath him. "He ordered us to do it," he plead.

"Who ordered it done?" demanded Tarzan.

"Underlieutenant von Goss," replied the soldier. "He, too, is here."

"I shall find him," returned Tarzan, grimly. "You helped to crucify Wasimbu, the Waziri, and, while he suffered, you laughed."

The fellow reeled. It was as though in the accusation he read also his death sentence. With no other word Tarzan seized the man again by the neck. As before there was no outcry. The giant muscles tensed. The arms swung quickly upward and with them the body of the black soldier who had helped to crucify Wasimbu, the Waziri, described a circle in the air—once, twice, three times, and then it was flung aside and the ape-man turned in the direction of General Kraut's headquarters.

A single sentinel in the rear of the building barred the way. Tarzan crawled, belly to the ground, toward him, taking advantage of cover as only the jungle-bred beast of prey can do. When the sentinel's eyes were toward him, Tarzan hugged the ground, motionless as stone; when they were turned away, he moved swiftly forward. Presently he was within charging distance. He waited until the man had turned his back once more and then he rose and sped noiselessly down upon him. Again there was no sound as he carried the dead body with him toward the building.

The lower floor was lighted, the upper dark. Through the windows Tarzan saw a large front room and a smaller room in rear of it. In the former were many officers. Some moved about talking to one another, others sat at field tables writing. The windows were open and Tarzan could hear much of the conversation; but nothing that interested him. It was mostly about the German successes in Africa and conjectures as to when the German army in Europe would reach Paris. Some said the Kaiser was doubtlessly already there, and there was a great deal of damning Belgium.

In the smaller back room a large, red-faced man sat behind a table.
