"You stood in the mess-room doorway listening to discover whose voice spoke from where. When I raised my head and saw you, though your eyes rested on my face there was no recognition in them. I suspected then. When you came down the steps into the verandah I became almost certain. When you would not help yourself to food, when you reached out your arm over your shoulder so that Moussa had to put the brandy-and-soda safely into your palm, I was sure."
"I was a fool to try and hide it," said Durrance. "Of course I knew all the time that I couldn't for more than a few hours. But even those few hours somehow seemed a gain."
"How did it happen?"
"There was a high wind," Durrance explained. "It took my helmet off. It was eight o'clock in the morning. I did not mean to move my camp that day, and I was standing outside my tent in my shirt-sleeves. So you see that I had not even the collar of a coat to protect the nape of my neck. I was fool enough to run after my helmet; and—you must have seen the same thing happen a hundred times—each time that I stooped to pick it up it skipped away; each time that I ran after it, it stopped and waited for me to catch it up. And before one was aware what one was doing, one had run a quarter of a mile. I went down, I was told, like a log just when I had the helmet in my hand. How long ago it happened I don't quite know, for I was ill for a time, and afterwards it was difficult to keep count, since one couldn't tell the difference between day and night."
Durrance, in a word, had gone blind. He told the rest of his story. He had bidden his followers carry him back to Berber, and then, influenced by the natural wish to hide his calamity as long as he could, he had enjoined upon them silence. Calder heard the story through to the end, and then rose at once to his feet.
"There's a doctor. He is clever, and, for a Syrian, knows a good deal. I will fetch him here privately, and we will hear what he says. Your blindness may be merely temporary."
The Syrian doctor, however, pursed up his lips and shook his head. He advised an immediate departure to Cairo. It was a case for a specialist. He himself would hesitate to pronounce an opinion; though, to be sure, there was always hope of a cure.
"Have you ever suffered an injury in the head?" he asked. "Were you ever thrown from your horse? Were you wounded?"
"No," said Durrance.
The Syrian did not disguise his conviction that the case was grave; and after he had departed both men were silent for some time. Calder had a feeling that any attempt at consolation would be futile in itself, and might, moreover, in betraying his own fear that the hurt was irreparable, only discourage his companion. He turned to the pile of letters and looked them through.
