The Arabs who approached us, having ridden straight into a trap for all they knew, for they had expected friends and found strangers, were even more than usually observant of formality.

They were fierce, fine-looking fellows, possessed of that dignity that only warfare with the desert breeds, and they saluted Grim with the punctilio of men who know the meaning of a fight to him who doubtless understands it too. A very different matter, that, to raising your Stetson on Broadway, with two cops on the corner and the Stars and Stripes floating from the hotel roof. They eyed Grim the while in the same sort of way that men who might be charged with trespa.s.s look at the game warden, waiting for him to speak first.

_"Allah ysabbak bilkhair!"_ he rolled out at last.

_"Allah y'a fik, ya Ali Higg!"_ they answered one after the other.

And then the oldest of them--a black-bearded stalwart with extremely aquiline nose and dark-brown eyes that fairly gleamed from under the linen head-dress, took on himself the role of spokesman.

"O Ali Higg! May Allah give you peace!"

"And to you peace!" Grim answered.

I could not see Grim's face, of course, since I stood behind him, but I did not detect the least movement of surprise or nervousness. He stood as if he were used to being called by that name, but the rest of us did not dare look at one another.

Once across that railway-line we were in the real Ali Higg's preserves. It occurred to me at the moment as vastly safer to pose as the U.S. President in Washington.

Still, Grim had not actually accepted the situation yet. I held my breath, trying to remember to look like a product of Lah.o.r.e University.

"We were on our way to El-Maan, O Ali Higg, not knowing that your honor had a hand in this affair."

"Since when is a lion not called a lion?" demanded Grim. "Who gave thee leave to name me?"

"Pardon, O Lion of Petra! But the woman yonder, boasting with proper pride that she is Your Honor's wife, bade us approach and pay respect."

On my left I heard Narayan Singh muttering obscenities through set teeth. On the right old Ali Baba wore a twinkle in a wicked eye; the rest of his face was as emotionless as the face of the desert; but when an old man is amused not even the crow's-feet can do less than advertise the fact.

"A woman's tongue is like a camel bell," said Grim. "It clatters unceasingly, and none can silence without choking it. But art thou a woman?"

"Pardon, O Lion of Petra!"

There followed a long pause. When men meet in the desert it is only those from the West who are in any hurry to betray their business. There being an infinity of time, that man is a liar who proclaims a shortage of it.

"Will the sun not rise tomorrow?" asks the East.

Grim stood like a statue; and, judging by my own feelings, who had nothing at all to do but look on, I should say that was a test of strength.

"Last week the train was punctual at El-Maan--three hours after sunrise," said the spokesman at last.

On lines where there is only one train a week it is not unusual for its arrival to be the chief social event on the country-side, but that hardly seemed to me to account for the way those five men had been driving their camels. However, as Grim knew no more of their business than the rest of us, and needed desperately to find out, he was careful to ask no questions.

No desert responds to the inquisitive folk who camp on its edge and demand to be told; but it will tell you all it knows if you keep quiet and govern yourself in accordance with its moods. The men who live in the desert are of the same pattern--fierce, hot, cold, intolerant, cruel, secretive, given to covering their tracks, and yet not without oases that are better than much fine gold to the man who knows how to find them. They enjoy a proverb better than some other men like promises.

"Allah marks the flight of birds. Shall He not decree a train's journey?" said Grim.

_"Inshallah,_ Lion of Petra! The train will come, when that is written, and that which is written shall befall. It is said there are sons of corruption on the train, who bear much wealth with them.

"It were a pity to leave all the looting to those who got to El-Maan soonest. They who slay will claim the booty.

"Or does Your Honor intend to arrive afterward and claim a share, leaving the labor to those who seek labor? In that case we crave permission to join Your Honor's party. It may be we can help enforce Your Honor's just demands, and be recompensed accordingly?"

_"Wallahi!"_ Grim answered after a long pause. "Who sets himself to plunder trains without my leave? Have I been such short time in Petra that men doubt who rules here? Have I not said the train shall pa.s.s El-Maan and come thus far? Who dares challenge me? Do I wait here for nothing? Shall I be satisfied with a string of empty cars?"

The Arab turned and conferred for a moment with his four friends.

They shook their heads.

"O Lord of the Desert," he said after a minute, "none has heard of this decree. Your Honor's messenger may have failed or have fallen into bad hands on the way. Word has not come that you reserve this train for your own profit. There will be fifty men at El-Maan now waiting to slay certain pa.s.sengers and plunder others."

Grim had evidently made up his mind and had set full sail on the course indicated. I confess I shuddered at the prospect; but I never saw a man look more pleased than Ali Baba, and Narayan Singh's face betrayed militant admiration. Nor have I ever heard such a streak of fulminous bad language as Grim swore then, calling earth and all its elements to witness the brimstone anger of a robber chief.

"Go ye," he thundered, "and tell those sons of swine that I say the train shall pa.s.s to this point. And as to what happens thereafter that is my affair. Bid any and all who chose to dispute my word to look first to their wives and goods. I have spoken."

The five men fell back a pace in consternation, no doubt partly affected for the sake of flattery; but they were quite obviously disconcerted.

_"Wallahi!_ If we go on such an errand who shall save our lives?

Who are we to come between wolves and their prey?"

"Say ye are my messengers," retorted Grim. "Let any touch a messenger of mine who dares."

"But they will not believe us."

"That is their affair. It is Allah's way to make blind those who it is written are to be destroyed."

"Nay, Lion of Petra, give a man to go with us--one whom they will know and recognize. Then all shall be well."

Have I ever said that Grim is a genius? He can take longer chances in a crisis with a more unerring aim than any man I ever knew. Surely he took one then.

"Nay," he laughed. "I will send them a woman. Let us see who will dare gainsay the woman."

That was simply supreme genius. It even pleased Narayan Singh, since the tables were turned on Ayisha. The only reason she could possibly have had for telling these men that Grim was Ali Higg was to score off him, either by capturing him for herself, or in the alternative by ruining him for rejecting her advances. It was not clear yet which of the two she hoped to accomplish; perhaps, little savage that she was, she would have been content with either alternative and had simply chosen to force the issue.

At any rate Grim had pa.s.sed the buck back to her. He sent me over to the rock to fetch her, and I found her smiling serenely, like the Sphinx, only with more than a modic.u.m of added mischief.

"Woman, the Lion of Petra summons you," said I.

She laughed at that as if the world were at her feet--got up, and stretched herself, and yawned like a lazy cat that sees the milk being set down in a saucer--straightened her dress, and nodded knowingly to her four men. She had evidently reached an understanding with them.

"I hasten to do my lord's bidding," she answered, and followed me back.

It calls for all your presence of mind to remember to walk in front of a woman who is addressed as often as not as princess; but if I had walked behind her they would have suspected me at once of being no true Moslem.

I returned and stood behind Grim, and she stood in front of him, so that I was able to see her face. It was as good as a show to see her swallow back surprise and wonder at him open-eyed, as he played the part she had foisted on him and loaded her with the responsibility.

"Go with these men, Ayisha, and tell those swine at El-Maan that I say the train shall pa.s.s unharmed as far as this point.

Moreover, say that none may trespa.s.s. What shall take place here is my affair. The range of my rifle is the measure of the line across which none may come.

"Stay with them, Ayisha, until the train leaves El-Maan. Then you may leave your camel and return hither on the train. That is my order."

She was bluffed. And she recognized it with a sort of dog-like glance of admiration. We had all her baggage, for one thing, and it represented more wealth than any Bedouin woman would let go willingly.
