We strained to listen. Through Ali’s black basalt window-frame crept a rustling, which was the stirring of the night-wind in the withered palms, an intermittent rustling, like English rain on yet-crisp fallen leaves. Then the cries came again and again and again, rising slowly in power, till they sobbed round the walls in deep waves to die away choked and miserable. At such times our men pounded the coffee harder while the Arabs broke into sudden song to occupy their ears against the misfortune. No Bedouin would lie outside in wait for the mystery, and from our windows we saw nothing but the motes of water in the dank air which drove through the radiance of our firelight. So it remained a legend: but wolves or jackals, hyaenas, or hunting dogs, their ghost-watch kept our ward more closely than arms could have done.
