The warring tiger does not move slowly. Half-a-minute after his would-be captor had crashed headlong to the hard cobbles of Aix-la-Chapelle, Dalroy was creeping between two wagons, completing a hasty toilet by tearing off collar and tie, and smearing his face and hands with oil and grease from lamp and cap. Even as he went he heard a window of the waiting-room being flung open, and the excited cries which announced the discovery of a half-naked body lying beneath in the gloom. He saw now that to every van was harnessed a pair of horses, their heads deep in nose-bags, while men in the uniform of the Commissariat Corps were grouped around an officer who was reading orders. The vans were sheeted in black tarpaulins. With German attention to detail, their destination, contents, and particular allotment were stencilled on the covers in white paint: "Liège, baggage and fodder, cavalry division, 7th Army Corps." He learnt subsequently that this definite legend appeared on front and rear and on both sides. Thinking quickly, he decided that the burly person whose outer garments he was now wearing had probably been taking a short cut to the station entrance when he received the surprise of his life. Somewhat higher up on the right, therefore, Dalroy went back to the narrow pavement close to the wall, and saw some soldiers coming through a doorway a little ahead. He made for this, growled a husky "Good-morning" to a sentry stationed there, entered, and mounted a staircase. Soon he found himself on the main platform; he actually passed a sergeant and some Bavarian soldiers, bent on recapturing the escaped prisoner, rushing wildly for the same stairs. None paid heed to him as he lumbered along, swinging the lamp. A small crowd of officers, among them the youthful prince in the silver _Pickel-haube_, had collected near the broken window and now open door of the waiting-room from which the "spy" had vanished. Within was the fat lieutenant of reserves, gesticulating violently at a pallid sentry. The prince was laughing. "He can't get away," he was saying. "A bold rascal. He must be quieted with a bayonet-thrust. That's the best way to inoculate an Englishman with German _Kultur_." Of course this stroke of rare wit evoked much mirth. Meanwhile, Dalroy was turning the key in the lock which held Irene Beresford in safe keeping until Von Halwig had discharged certain pressing duties as a staff officer. The girl, who was seated, gave him a terrified glance when he entered, but dropped her eyes immediately until she became aware that this rough-looking visitor was altering the key. Dalroy then realised by her startled movement that his appearance had brought fresh terror to an already overburthened heart. Hitherto, so absorbed was he in his project, he had not given a thought to the fact that he would offer a sinister apparition.
