He hurried along with John at the head of the party through the desolate blackened street until he reached the palm-trees, where he expected to find the camp. To his surprise there was no sign of an encampment having been there, nor, looking round, could he discover Challis or any of the boys. "What does this mean, John?" he asked, feeling very uneasy. John looked puzzled for a moment or two; then his face lightened as the explanation struck him. "Boys 'fraid of debbils, sah," he said. "Massa Chally find 'nother place." Somewhat relieved, Royce hastened on with the man, hoping to see his friend at no great distance. In a few minutes they caught sight of the scattered material of the zariba. In the enclosure was a round mark upon the ground, indicating where the tent had stood, and blackened spots where the men had kindled their fires. But all the baggage was gone, except one tent-peg. There was nothing else save a number of empty banana skins. Royce paused in dismay. John looked about with the air of a man in fear. And then there was a sudden cry from one of the carriers, as they came up toiling under their loads. They halted, dropped their burdens, and, collecting in a group, stood staring at the ground. Royce and John hurried to them, wondering what had attracted their attention. They were looking with terror at some dull reddish splashes on the soil. Royce's heart sank. It was inconceivable that Challis had moved camp of his own accord. He must have been attacked. The bloodstains seemed to indicate that there had been a fight; yet they were very few, and all at one spot. He looked about, dreading to see dead bodies in the neighbourhood of the enclosure. The relief he felt at finding none was smothered by a great anxiety. It seemed only too certain that, fight or no fight, the camp had been captured, and all within it carried away. For some little time they all stood silent. Then the headman suddenly started, threw up his arms, and with a howl of fright took to his heels, and ran fleetly back along the way he had come. Instantly his companions followed him; in a few seconds they had disappeared. Royce was left alone with John. The Hausa had already discovered the cause of their sudden stampede. He had caught sight of a black form skulking among some thin bush at no great distance from the camp. Just as he pointed him out to his master, looking much inclined to bolt after the carriers, the figure moved towards them, hastening its steps, and revealing itself to be that of one of their own men. The carriers, no doubt, had supposed him to be one of the party who had rushed the camp, and feared that the rest were somewhere near.
