"How old beards love to wag! Fool! Go ask him then! I call these men to witness I have given the order that he told me to give to you. I wash my hands!"

She began to make the gesture of washing hands, but thought better of it, for I might have mistaken that for a signal. Old Ibrahim ben Ah looked straight into her eyes, read resolution there, and bowed like a courtier to a queen. Then he turned on his heel, strode back to his camel, mounted, and returned to his men without another word to any one. Yet I dare bet that he had counted us, and knew we were all strangers, and dare say his thoughts would fill a good long chapter of a book.

Grim continued to sit his camel motionless until the raiders under Ibrahim ben Ah had formed into four long lines and ridden away westward, towing enough baggage-animals behind them for a week or two's supplies.

"One hundred and forty men," he announced when they were gone.
"The Lion of Petra can't have many left."

CHAPTER IX

"I Think We've Got the Lion of Petra on the Hip!"

Grim is one of those fellows who tell you their principles as grudgingly as they let out facts. He would make the poorest sort of propagandist or politician, for he doesn't advertise, and hates long arguments. What he knows he knows is so because it works; and he proceeds to put it to work.

Nor is he much of a teacher. He takes people as he finds them and adapts his plans accordingly. So it is only from observation extended over a considerable period in all sorts of circumstances that I can say I believe his first and underlying principle is to look for the positive, concrete usefulness in any one with whom he is associated, whether friend or enemy. And this I have heard him say several times.

"In secret service you limit yourself if you make plans. The game is to listen and watch. Presently the other fellow always tells his plans or else betrays them."

And he is no such fool as to be caught in the act of listening, or to forewarn his enemy by seeming to wish to listen.
