"That doesn't help us much," said the major.
"And it's all you know?" asked the colonel.
"No, not quite all," returned Calder, slowly; "I know, for instance, that the man we are talking about is staring me straight in the face."
At once everybody at the table turned towards the mess-room.
"Durrance!" cried the colonel, springing up.
"When did you get back?" said the major.
Durrance, with the dust of his journey still powdered upon his clothes, and a face burnt to the colour of red brick, was standing in the doorway, and listening with a remarkable intentness to the voices of his fellow-officers. It was perhaps noticeable that Calder, who was Durrance's friend, neither rose from his chair nor offered any greeting. He still sat watching Durrance; he still remained curious and perplexed; but as Durrance descended the three steps into the verandah there came a quick and troubled look of comprehension into his face.
"We expected you three weeks ago," said Dawson, as he pulled a chair away from an empty place at the table.
"The delay could not be helped," replied Durrance. He took the chair and drew it up.
"Does my story account for it?" asked Calder.
"Not a bit. It was the Greek musician I expected that night," he explained with a laugh. "I was curious to know what stroke of ill-luck had cast him out to play the zither for a night's lodging in a cafe at Tewfikieh. That was all," and he added slowly, in a softer voice, "Yes, that was all."
"Meanwhile you are forgetting your breakfast," said Dawson, as he rose. "What will you have?"
Calder leaned ever so slightly forward with his eyes quietly resting on Durrance. Durrance looked round the table, and then called the mess-waiter. "Moussa, get me something cold," said he, and the waiter went back into the mess-room. Calder nodded his head with a faint smile, as though he understood that here was a difficulty rather cleverly surmounted.
"There's tea, cocoa, and coffee," he said. "Help yourself, Durrance."
"Thanks," said Durrance. "I see, but I will get Moussa to bring me a brandy-and-soda, I think," and again Calder nodded his head.
Durrance ate his breakfast and drank his brandy-and-soda, and talked the while of his journey. He had travelled farther eastward than he had intended. He had found the Ababdeh Arabs quiet amongst their mountains. If they were not disposed to acknowledge allegiance to Egypt, on the other hand they paid no tribute to Mahommed Achmet. The weather had been good, ibex and antelope plentiful. Durrance, on the whole, had reason to be content with his journey. And Calder sat and watched him, and disbelieved every word that he said. The other officers went about their duties; Calder remained behind, and waited until Durrance should finish. But it seemed that Durrance never would finish. He loitered over his breakfast, and when that was done he pushed his plate away and sat talking. There was no end to his questions as to what had passed at Wadi Halfa during the last eight weeks, no limit to his enthusiasm over the journey from which he had just returned. Finally, however, he stopped with a remarkable abruptness, and said, with some suspicion, to his companion: "You are taking life easily this morning."
"I have not eight weeks' arrears of letters to clear off, as you have, Colonel," Calder returned with a laugh; and he saw Durrance's face cloud and his forehead contract.
"True," he said, after a pause. "I had forgotten my letters." And he rose from his seat at the table, mounted the steps, and passed into the mess-room.
Calder immediately sprang up, and with his eyes followed Durrance's movements. Durrance went to a nail which was fixed in the wall close to the glass doors and on a level with his head. From that nail he took down the key of his office, crossed the room, and went out through the farther door. That door he left open, and Calder could see him walk down the path between the bushes through the tiny garden in front of the mess, unlatch the gate, and cross the open space of sand towards his office. As soon as Durrance had disappeared Calder sat down again, and, resting his elbows on the table, propped his face between his hands. Calder was troubled. He was a friend of Durrance; he was the one man in Wadi Halfa who possessed something of Durrance's confidence; he knew that there were certain letters in a woman's handwriting waiting for him in his office. He was very deeply troubled. Durrance had aged during these eight weeks. There were furrows about his mouth where only faint lines had been visible when he had started out from Halfa; and it was not merely desert dust which had discoloured his hair. His hilarity, too, had an artificial air. He had sat at the table constraining himself to the semblance of high spirits. Calder lit his pipe, and sat for a long while by the empty table.
Then he took his helmet and crossed the sand to Durrance's office. He lifted the latch noiselessly; as noiselessly he opened the door, and he looked in. Durrance was sitting at his desk with his head bowed upon his arms and all his letters unopened at his side. Calder stepped into the room and closed the door loudly behind him. At once Durrance turned his face to the door.
"Well?" said he.
"I have a paper, Colonel, which requires your signature," said Calder. "It's the authority for the alterations in C barracks. You remember?"
"Very well. I will look through it and return it to you, signed, at lunch-time. Will you give it to me, please?"
He held out his hand towards Calder. Calder took his pipe from his mouth, and, standing thus in full view of Durrance, slowly and deliberately placed it into Durrance's outstretched palm. It was not until the hot bowl burnt his hand that Durrance snatched his arm away. The pipe fell and broke upon the floor. Neither of the two men spoke for a few moments, and then Calder put his arm round Durrance's shoulder, and asked in a voice gentle as a woman's: "How did it happen?"
Durrance buried his face in his hands. The great control which he had exercised till now he was no longer able to sustain. He did not answer, nor did he utter any sound, but he sat shivering from head to foot.
"How did it happen?" Calder asked again, and in a whisper.
Durrance put another question: "How did you find out?"
"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."
