As we got near we saw through the palm-trees flame, and the flame-lit smoke of many fires, while the hollow ground reechoed with the roaring of thousands of excited camels, and volleying of shots or shoutings in the darkness of lost men, who sought through the crowd to rejoin their friends. As we had heard in Yenbo that the Nakhl were deserted, this tumult meant something strange, perhaps hostile. We crept quietly past an end of the grove and along a narrow street between man-high mud walls, to a silent group of houses. Abd el Kerim forced the courtyard door of the first on our left, led the camels within, and hobbled them down by the walls that they might remain unseen. Then he slipped a cartridge into the breech of his rifle and stole off on tiptoe down the street towards the noise to find out what was happening. We waited for him, the sweat of the ride slowly drying in our clothes as we sat there in the chill night, watching.
