“You are a pig, and the son of a pig,” replied Dimoussi calmly. “Have you any powder?”

He changed his ninth dollar and bought some powder.

“You will need bullets, too,” said Mustapha. “I will sell you them very cheap. Oh, you are lucky! Do you see those signs upon the barrel? The pistol is charmed and cannot miss.”

Dimoussi looked at the signs engraved one above the other on the barrel. There was a crown, and a strange letter, and a lion. He had long wondered what those signs meant. He was very glad now that he understood.

“But I will not buy lead bullets,” said Dimoussi wisely. “The pistol may be enchanted so that it cannot miss, but there are also enchantments against lead bullets so that they cannot hurt.”

So Dimoussi walked away, and begged a lump of rock salt from another booth instead. He cut down the lump until it fitted roughly into the hexagonal barrel of his pistol. Then he loaded the pistol, and hiding the weapon in the wide sleeve of his jellaba, sauntered to the great square before the Renegade’s Gate. There were groups of people standing about watching the tents, and the inevitable ring of sentries. But while Dimoussi was still loitering—he would have loitered for a fortnight if need be, for there were no limits to Dimoussi’s patience—Arden came out of the tent with his camera, and Challoner followed with a tripod stand.

The two consools passed the line of guards and set up the camera in front of the Renegade’s Gate. Dimoussi was quite impartial which of the two should be sacrificed to begin the djehad, but again an ironical fate laid its hand upon him. It was Arden who was to work the camera. It was Arden, therefore, who was surrounded by the idlers, and was safe. Challoner, on the other hand, had to stand quite apart, so as to screen the lens from the direct rays of the sun.

“A little more to the right, Challoner,” said Arden. “That’ll do.”

He put his head under the focussing cloth, and the next instant he heard a loud report, followed by shouts and screams and the rush of feet; and when he tore the focussing cloth away he saw Challoner lying upon the ground, the sentries agitatedly rushing this way and that, and the bystanders to a man in full flight.

Dimoussi had chosen his opportunity well. He stood between two men, and rather behind them, and exactly opposite Challoner. All eyes were fixed upon the camera, even Challoner’s. It was true that he did see the sun glitter suddenly upon something bright, that he did turn, that he did realise that the bright thing was the brass barrel of a big flintlock pistol. But before he could move or shout, the pistol was fired, and a heavy blow like a blow from a cudgel struck him full on the chest.
