Ali clapped a hand over his mouth to stifle a gasp. The Jackal was indeed playing for big stakes, one of the most colossal prizes in the history of brigandage, and he seemed in a fair position to get it. Fixed in the wall of The Kaaba, an edifice so ancient that some claimed it was here even before Mohammed, The Black Stone was possibly the holiest of Moslem shrines. In common with all other pilgrims, Ali had dutifully kissed it. As far as its physical aspects were concerned, it was a small, dark mass that at one time might have been part of a meteor. Should anyone ever succeed in stealing it, the Moslem world would pay a fantastic ransom for its safe return. If nobody stopped The Jackal and his accomplices, each of them could be so wealthy that the Pasha of Damascus would seem a beggar by comparison.

Ben Akbar swung his head to nudge Ali's shoulder with an inquiring nose, and Ali stroked the dalul's soft cheek. Accustomed to spending his nights in some peaceful pasture, Ben Akbar had no liking for this confined place, and he was telling his friend so.

Ali tried to conjure up a mental image of The Sacred Course, but he couldn't do it, in spite of the fact that he had run its length the stipulated seven times. Because he had hoped to find that in their faces which would tell him just why they had come to Mecca, and thus furnish some sure basis upon which he could build his own right motivation for coming, Ali had studied his fellow pilgrims and ignored the street. Who could imagine that he or anyone else might have to leave The Masa by the nearest and quietest path?

There had to be a way because there was always a way, but Ali was still seeking it when Ben Akbar, increasingly eager to be out of the city that he did not like and into the desert he did, expressed his impatience in a racking grunt.

Then there was just one way. Ali drew his dagger and waited.

Out in the night, there was sudden silence, but the very lack of noise was as lethal as and somehow remarkably similar to the desert adder that awaits its prey in complete silence and, in striking, makes no noise that is ever heard by the victim. Ali considered the situation.

Since it was most improbable that there'd be a camel at this place and hour without a camel driver, the conspirators knew they had been overheard. In addition, since every camel has its own distinctive voice, The Jackal had probably recognized Ben Akbar. Therefore, he knew that Ali had overheard him.

Swiftly, Ali weighed the advantages and disadvantages and considered possible ways to make the best use of the former, while yielding as little as possible to the latter.

Beyond any doubt, The Jackal knew that Ben Akbar accepted certain favored human beings and rejected all others, unless they foolishly tried to interfere with him. Then he showed his resentment, often violently. So only a fool would rush in, and The Jackal was no fool. Neither, Ali told himself, was he a coward who'd be swerved from his determined purpose by a threatening incident. He'd face a dozen Ben Akbars before he'd abandon his plan to steal The Black Stone and seek refuge in flight, but he'd face them in his own way. Ali took a calculated risk.

"Kneel," he whispered in the dalul's ear.
