Capper laughed like the philosopher who has just discovered the absolute of life's futility. The ticket—his ticket from the Wilhelmstrasse which Louisa had procured for him; Louisa wanted that for other purposes, and used him as the dummy to obtain it. She wanted it before he could arrive at Malta—and she got it before he left Marseilles. Even Louisa, the wise, had played without discounting the Double 0 on the wheel—fate's percentage in every game; she could not know the Vendée would be warned from lingering at Malta because of the exigency of war, and that Billy Capper would reach Alexandria, after all.
The green logic in the glass carried Capper along with mathematical exactness of deduction. As he sipped, his mind became a thing detached and, looking down from somewhere high above earth, reviewed the blundering course of Billy Capper's body from Berlin to Alexandria—the poor deluded body of a dupe. With this certitude of logic came the beginnings of resolve. Vague at first and intangible, then, helped by the absinth to focus, was this new determination. Capper nursed it, elaborated on it, took pleasure in forecasting its outcome, and viewing himself in the new light of a humble hero. It was near morning, and the Tavern of Thermopylæ was well-nigh deserted when Capper paid his score and blundered through the early-morning crowd of mixed races to his hotel. His legs were quite drunk, but his mind was coldly and acutely sober.
"Very drunk, master," was the report Cæsar, the Numidian, delivered to Doctor Koch at the Ramleh villa. The doctor, believing Cæsar to be a competent judge, chuckled in his beard. Cæsar was called off from the trail.
Across the street from Doctor Koch's home on Queen's Terrace was the summer home of a major of fusileers, whose station was up the Nile. But this summer it was not occupied. The major had hurried his family back to England at the first mutterings of the great war, and he himself had to stick by his regiment up in the doubtful Sudan country. Like Doctor Koch's place, the major's yard was surrounded by a high wall, over which the fronds of big palms and flowered shrubs draped themselves. The nearest villa, aside from the Kochs' across the street, was a hundred yards away. At night an arc light, set about thirty feet from Doctor Koch's gate, marked all the road thereabouts with sharp blocks of light and shadow. One lying close atop the wall about the major's yard, screened by the palms and the heavy branches of some night-blooming ghost flower, could command a perfect view of Doctor Koch's gateway without being himself visible.
At least, so Billy Capper found it on the night following his visit to the German physician's and his subsequent communion with himself at the Tavern of Thermopylæ. Almost with the falling of the dark, Capper had stepped off the train at Ramleh station, ferried himself by boat down the canal that passed behind the major's home, after careful reconnoitering, discovered that the tangle of wildwood about the house was not guarded by a watchman, and had so achieved his position of vantage on top of the wall directly opposite the gateway of No. 32. He was stretched flat. Through the spaces between the dry fingers of a palm leaf he could command a good view of the gate and of the road on either side. Few pedestrians passed below him; an automobile or two puffed by; but in the main, Queen's Terrace was deserted and Capper was alone. It was a tedious vigil. Capper had no reliance except his instinct of a spy familiar with spy's work to assure that he would be rewarded for his pains. Some sixth sense in him had prompted him to come thither, sure in the promise that the night would not be misspent. A clock somewhere off in the odorous dark struck the hour twice, and Capper fidgeted. The hard stone he was lying on cramped him.
The sound of footsteps on the flagged walk aroused momentary interest. He looked out through his screen of green and saw a tall well-knit figure of a man approach the opposite gate, stop and ring the bell. Instantly Capper tingled with the hunting fever of his trade. In the strong light from the arc he could study minutely the face of the man at the gate—smoothly shaven, slightly gaunt and with thin lips above a strong chin. It was a striking face—one easily remembered. The gate opened; beyond it Capper saw, for an instant, the white figure of the Numidian he had bumped into at the alley's mouth. The gate closed on both.
Another weary hour for the ferret on the wall, then something happened that was reward enough for cramped muscles and taut nerves. An automobile purred up to the gate; out of it hopped two men, while a third, tilted over like one drunk, remained on the rear seat of the tonneau. One rang the bell. The two before the gate fidgeted anxiously for it to be opened. Capper paid not so much heed to them as to the half-reclining figure in the machine. It was in strong light. Capper saw, with a leap of his heart, that the man in the machine was clothed in the khaki service uniform of the British army—an officer's uniform he judged by the trimness of its fitting, though he could not see the shoulder straps. The unconscious man was bareheaded and one side of his face was darkened by a broad trickle of blood from the scalp.
When the gate opened, there were a few hurried words between the Numidian and the two who had waited. All three united in lifting an inert figure from the car and carrying it quickly through the gate. Consumed with the desire to follow them into the labyrinth of the doctor's yard, yet not daring, Capper remained plastered to the wall.
Captain Woodhouse, sitting in the consultation room with the doctor, heard the front door open and the scuffle of burdened feet in the hall. Doctor Koch hopped nimbly to the folding doors and threw them back. First, the Numidian's broad back, then, the bent shoulders of two other men, both illy dressed, came into view. Between them they carried the form of a man in officer's khaki. Woodhouse could not check a fluttering of the muscles in his cheeks; this was a surprise to him; the doctor had given no hint of it.
"Good—good!" clucked Koch, indicating that they should lay their burden on the operating chair. "Any trouble?"
