When, presently, the Arab ceased, his tongue positively lolling out of his mouth like that of a thirsty dog, Sir Richard turned to Anstice with an air of determination.

"Things have been moving, with a vengeance, in our absence," he said grimly. "It seems that yesterday morning early young Garnett found a couple of Bedouins prowling about his place and helping themselves to his choicest produce; and being a hotheaded young fool he let fly at them with his revolver, the result being that by a most unlucky chance he winged one of the rascals and the other assisted him off, vowing vengeance on the whole little English colony of eight souls. It was not an empty threat either; for when Hassan, feeling uneasy at the idea of harm coming to Iris, slunk into the village to find out, if possible, what mischief was afoot, he ran slick into a conclave of the brutes, and hiding behind a rock heard their plans."

"They were pretty deadly, I suppose?"

"They merely embraced the wholesale massacre, under cover of night, of the English men and women who had been fools enough to trust their good faith," returned Sir Richard shortly. "Well, Hassan, whose wits are as sharp as his ears are long, lost no time in going back to his mistress with the information; and between them they evolved a plan which might, with the most marvellous luck, be successful."

"And that plan, sir?" Anstice's tone was tense.

"Aided by Hassan, at the approach of night the whole little group of white people crept safely into the Fort of which I told you; and when, a couple of hours later, the Bedouins came forth intent on reprisals, they found the houses of the English empty, and realized, too late, that the Fort was quite a different nut to crack."

"It is a fairly safe building?"

"Well, it has certain natural advantages, I grant." Sir Richard spoke rather dubiously. "We went over it one day, in a spirit of curiosity; and I have a pretty clear recollection of the place. To begin with, as I told you the Bedouin encampment is a sort of oasis in a valley at the foot of some quite respectably high rocks. You know the desert is not, as some people imagine, merely a flat expanse of sand. Here and there are ranges of hills, limestone, and so on—and now and then one comes across quite a chain of rocky places which in another country would be looked upon as precipices."

He paused; and Anstice waited eagerly for him to continue.

"Well, this Fort is, very luckily, built on a plateau overlooking the valley. On one side the ground slopes gently down to the little colony, but on the other the Fort overlooks a high precipice of rock which of course affords no means of transit from the ground below; so that on that side the place is absolutely impregnable."
