"Whither do you fly with the white Egyptian?"

"If you come and see you will know, by the mercy of God!" answered
Mahmoud.

The next instant the dervishes charged. Macnamara marked his man, and the man with the jibbeh fell from his camel. Mahmoud fired his carbine, missed, and closed with his enemy. Macnamara, late of the 7th Hussars, swung his Arab sword as though it were the regulation blade and he in sword practice at Aldershot, and catching the blade of his desert foe, saved his own neck and gave the chance of a fair hand-to-hand combat.

He met the swift strokes of the dervish with a cool certainty. His weariness passed from him; the joy of battle was on him. He was wounded twice-in the shoulder and the head. Now he took the offensive. Once or twice he circled slowly round the dervish, whose eyes blazed, whose mouth was foaming with fury; then he came on him with all the knowledge and the skill he had got in little Indian wars. He came on him, and the dervish fell, his head cut through like a cheese.

Then Macnamara turned, to see Mahmoud and the third dervish on the ground, struggling in each other's arms. He started forward, but before he could reach the two, Mahmoud jumped to his feet with a reeking knife, and waved it in the air.

"He was a kinsman, but he had to die," said Mahmoud as they mounted. He turned towards the bodies, then looked at the camels flying down the desert towards Dongola.

"It is as God wills now," he said. "Their tribesmen will follow when they see the camels. See, my camel is wounded!" he added, with a gasp.

Two days following, towards evening, two wounded men on foot trudged through the desert haggard and bent. The feet of one—an Arab—had on a pair of red slippers, the feet of the other were bare. Mahmoud and Macnamara were in a bad way. They were in very truth "walking against time." Their tongues were thick in their mouths, their feet were lacerated and bleeding, they carried nothing now save their pistols and their swords, and a small bag of dates hanging at Macnamara's belt. Prepared for the worst, they trudged on with blind hope, eager to die fighting if they must die, rather than to perish of hunger and thirst in the desert. Another day, and they would be beyond the radius of the Khalifa's power: but would they see another day?

They thought that question answered, when, out of the evening pink and opal and the golden sand behind them, they saw three Arabs riding. The friends of the slain dervishes were come to take revenge, it seemed.
