"I renounce everything!" he cried. "I admit my guilt, and ask you to forgive me. I will give up all claim to a share in the treasure. I swear to be faithful to you, if you will only get me out of this alive."
"We do not think of the treasure," said Urquhart. "We are here to establish the innocence of an injured man and to checkmate von Hardenberg."
"It was he who stole the Sunstone," uttered Klein.
"I know that," said Harry. "That is why we have followed him. He may have the Black Dog of the Cameroons to aid him, but we have these two gallant fellows, who do not seem to know what it is to fear, to hesitate, or to give up hope."
He half turned, and with a motion of the hand indicated the two brothers, who were seated side by side.
Fernando slowly shook his head.
"As you will," said he. "You have yet to learn that the Cameroons is no place for clemency. I had a plan to trick the Black Dog. It was a cruel plan perhaps. I meant to sacrifice this cur like a kid tied to a stake to snare a tiger. However, let that pass. From to-night, I warn you fairly, we will be even in greater danger than before. We have an enemy to reckon with in the sheikh. At this very moment he waits on the hill-side for his victim." Fernando pointed to Peter Klein.
"He means to take my life!" cried Klein, who was now pacing to and fro, wringing his hands like one demented. "The moment they saw I was likely to be of no use to them, that I was a coward who could neither handle a rifle nor do a long day's march without fatigue, they schemed to do away with me. And what a place for a crime, these unknown, savage hills! In these parts a human life is of no more importance than that of a mosquito."
The man was overwrought, his nerves had been sadly shaken. He was on the verge of lunacy with panic and alarm.
And yet, what he said was obviously the truth. To von Hardenberg his presence was worse than useless, a mere encumbrance on the line of march. In all probability Fernando was right; the Black Dog waited on the hill-side to fall upon the poor, blind fool whom avarice had led so far from the land where he could spy and inform in safety.
