Safety lay in their making the best speed they could. Should any of the Arabs wake, he would almost certainly discover the absence of the prisoner, but it would be impossible to track him in the dark. With the dawn, however, the tracks would be easily picked up, and then their horses, refreshed, would regain the start if the pursuit was carried far enough. The dervish suggested that pursuit was unlikely. His captors belonged to a tribe that was in Turkish pay, and the neighbourhood of Meshed Ali, where the revolutionaries were strong, was by no means safe for supporters of the Padishah. But Ibrahim, unwilling to run risks, struck off from the highway into a stony district with which he had become familiar in the course of his business journeys. Here, even if they were pursued, it would be difficult to track them.

"I owe you my life," said the dervish to Burnet as they rode on, "and I thank you."

"I am only too glad. You helped me out of a hobble not so long ago; I never imagined I should have a chance of doing anything in return. But surely your life was not in danger?"

"There can't be much doubt of it. I heard that that old ruffian the chief Halil had gone to Bagdad, and knowing that there was some difference of opinion among his tribesmen as to his wisdom in siding with the Turks, I took advantage of his absence to visit them, in order to learn the strength of the opposition party and to do what I could to increase it—to foment treason, in fact. Some of Halil's people suspected me: they were quite right: and they only waited the return of their chief to denounce me. He came back unexpectedly. I had warning only just in time, and decamped. I had begun to think myself safe when those four fellows rode me down. No doubt there are scores more of the tribesmen hunting me in all directions. Halil has an old grudge against me: I crossed him once before."

"Then I am doubly lucky. Halil's business in Bagdad was to arrange an attack on Rejeb's people. He is back sooner than I thought possible, and I am glad to know it, as I should not have done but for meeting you. It is one more item in my budget of news for headquarters."

The conversation was conducted in Arabic. The identity of the dervish was known only to the headquarters staff and to Firouz Ali, and he always took particular care not to let fall the slightest hint that he was other than an Arab, even to fellow-workers in the same cause.

Ibrahim allowed his animals to finish their interrupted rest during the small hours, and the travellers started again at dawn. When they were still a mile or two distant from Meshed Ali, within sight of the glittering dome of its mosque towering high above the walls, the dervish dismounted.

"It will be better for us all if I enter the city alone," he said. "I shall not be long after you. But if we meet within the walls, let it be as strangers."

"You are a wise man, O dervish," said Ibrahim, "and I perceive that the spirit of Firouz Ali is in you. Allah will bring us all together openly in his good time."

Burnet and Ibrahim reached the city about an hour before noon, and passing through the one gate in its high brick walls, and along the crowded bazar, came to the khan or inn where Ibrahim had decided that they should part. After the Arab had attended to his beasts, he returned to the chief room, where traders, camel-drivers and others were squatting around the walls, ordered a meal, and then carried out the instructions of Firouz Ali.
