The Berber gave him a thoughtful glance. Kit was angry and his naive honesty was obvious. The Berber was subtle, but it did not look as if he doubted. Kit thought he weighed something; and then he looked up with a start.

He had heard a sharp report, and a thin streak of smoke curled about the automatic pistol. Sheep ran across the stubble, a camel got up, and Kit saw a small hole in the tent.

"Noo I ken what's wrang with his gun," Macallister remarked.

Holding the pistol in front he advanced towards the Berbers. None moved and the headman's look was imperturbable. Kit wondered whether the magazine held another cartridge and hoped nobody would move. He knew Macallister. The engineer stopped opposite the headman, and for a moment their glances met. Then he held out the pistol, with the butt to the other.

"For a camel thief, ye're a trustful person," he said dryly.

Kit had not seen a Berber laugh, but when Simon translated it looked as if the headman smiled. He signalled and across the wady a man with a modern rifle got up from behind a stone and another crawled out of the sand. Kit thought they were picked shots and had marked the range. All the same, he doubted if the headman knew there was a cartridge in the magazine. Macallister, stopping by the other, opened the pistol.

"Noo," he said, "ye see——"

His lingua franca was uncouth, but when he took some pieces from the pistol with his pocket knife it looked as if the headman saw. He was obviously interested, something of his reserve vanished, and presently he signed one of the others back and Macallister sat down on the piece of carpet by his side. The engineer gave Kit a smile he understood. It was as if he had said, "Ye dinna ken old Peter yet!"

Kit mused. He had borne some strain and was languid, and the headman was occupied. It was strange, but Macallister, by luck or talent, generally took the middle of the stage. Kit was not like that, but now chance had given him a leading part, the part must be played, and he weighed the arguments he had used. He had stated that he was poor and Wolf had vanished. If the chief were satisfied about this, there was obviously no use in his holding the party for ransom or to force payment of Wolf's debt. Then he had hinted that the Spanish government might send soldiers to search the country, and the Berber admitted that he had enemies who intrigued with the white men. Kit did not know another argument; perhaps he had said enough, and he waited.

By and by the headman talked to the interpreter, who said: "He wants to know why you landed the guns when you had not brought all."
