Major Walters pointed out his arm to the white empty desert across the river.
"If he had travelled that way, westward, I might agree," he said. "But Durrance went east through the mountain country toward Berenice and the Red Sea. The tribes he went to visit were quiet, even in the worst times, when Osman Digna lay before Suakin."
The colonel, however, took no comfort from Walters's confidence. He tugged at his moustache and repeated, "He is three weeks overdue."
Lieutenant Calder knocked the ashes from his pipe and refilled it. He leaned forward in his chair as he pressed the tobacco down with his thumb, and he said slowly:—
"I wonder. It is just possible that some sort of trap was laid for Durrance. I am not sure. I never mentioned before what I knew, because until lately I did not suspect that it could have anything to do with his delay. But now I begin to wonder. You remember the night before he started?"
"Yes," said Dawson, and he hitched his chair a little nearer. Calder was the one man in Wadi Halfa who could claim something like intimacy with Durrance. Despite their difference in rank there was no great disparity in age between the two men, and from the first when Calder had come inexperienced and fresh from England, but with a great ardour to acquire a comprehensive experience, Durrance in his reticent way had been at pains to show the newcomer considerable friendship. Calder, therefore, might be likely to know.
"I too remember that night," said Walters. "Durrance dined at the mess and went away early to prepare for his journey."
"His preparations were made already," said Calder. "He went away early, as you say. But he did not go to his quarters. He walked along the river-bank to Tewfikieh."
Wadi Halfa was the military station, Tewfikieh a little frontier town to the north separated from Halfa by a mile of river-bank. A few Greeks kept stores there, a few bare and dirty cafés faced the street between native cook-shops and tobacconists'; a noisy little town where the negro from the Dinka country jolted the fellah from the Delta, and the air was torn with many dialects; a thronged little town, which yet lacked to European ears one distinctive element of a throng. There was no ring of footsteps. The crowd walked on sand and for the most part with naked feet, so that if for a rare moment the sharp high cries and the perpetual voices ceased, the figures of men and women flitted by noiseless as ghosts. And even at night, when the streets were most crowded and the uproar loudest, it seemed that underneath the noise, and almost appreciable to the ear, there lay a deep and brooding silence, the silence of deserts and the East.
"Durrance went down to Tewfikieh at ten o'clock that night," said Calder. "I went to his quarters at eleven. He had not returned. He was starting eastward at four in the morning, and there was some detail of business on which I wished to speak to him before he went. So I waited for his return. He came in about a quarter of an hour afterwards and told me at once that I must be quick, since he was expecting a visitor. He spoke quickly and rather restlessly. He seemed to be labouring under some excitement. He barely listened to what I had to say, and he answered me at random. It was quite evident that he was moved, and rather deeply moved, by some unusual feeling, though at the nature of the feeling I could not guess. For at one moment it seemed certainly to be anger, and the next moment he relaxed into a laugh, as though in spite of himself he was glad. However, he bundled me out, and as I went I heard him telling his servant to go to bed, because, though he expected a visitor, he would admit the visitor himself."
