His wonder vanished before the necessity for action, as Professor Helmuth appeared at the entrance to her tent, a small wicker suitcase in her hand. Hammer took it as she reached his side, and motioned her to fall in ahead of him.

"Go ahead, Mohammed," he said. "You next, bos'n, with Jenson—no, you go with Mohammed, professor; I want to keep an eye on these two beauties. I guess Potbelly can take care of his own getaway."

The girl made no protest, but joined the native, and all five left the camp and the staring Kiswahili behind. A last backward glance showed Hammer that Potbelly was slowly retreating down the hill, and then the jungle had closed in about him and all behind was lost to sight, with only the green tangle on every hand and the backs of Baumgardner and Jenson in front, while through the shadow-haunted, sun-creeping mass of foliage came to him occasional glints of the white dress of Professor Helmuth.

Cyrus Hammer felt quite pleased with himself for once. He had bearded the lion in his den and had got clean off with the bone—meaning Jenson. As to Sara Helmuth, that was another matter and not one with which Hammer was not now greatly concerned. If she had been in trouble, she was out of it, and enough said.

But Jenson was going over the road, the American told himself grimly. To tell the truth, he was angry, more because the pallid little secretary had played with him than because he had committed perjury, and he was now intent on reopening the case of Schlak. Either Jenson or Solomon could tell who had killed the second mate, and why there had been a double perjury afterward.

As they tramped along, stumbling over vines and creepers, with the jungle wall dark and impenetrable on either hand, Hammer caught the two men ahead talking, and warned them against it with such savage intensity in his voice that they obeyed.

The American was perfectly well aware of the dangerous quality of the secretary by this time, and was surprised that Dr. Krausz had stood up for the man so boldly, even to defying the law.

For that matter, Krausz was apt to prove extremely dangerous himself, now that his open antagonism must have been aroused.

Hammer chuckled at the delight which had been so evident in the face of Potbelly.

The fellow had the quality, rare in natives, of acting on his own initiative, and the American hoped that he would get away in safety from the German party.
