"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.
