Nikky saw a great light. When Peter Niburg put his hand to his breast-pocket, there was no longer room for doubt, nor, for that matter, time for thinking. As a matter of fact, never afterward could Nikky recall thinking at all. He moved away quietly, hidden by the shadows of the colonnade. Behind him, on the steps, the two men were talking. Peter Niburg’s nasal voice had taken on a whining note. Short, gruff syllables replied. Absorbed in themselves and their business, they neither heard nor saw the figure that slipped through the colonnade, and dropped, a bloodcurdling drop, from the high end of it to the street below.

Nikky’s first impulse, beside the car, was to cut a tire. By getting his opponent into a stooping position; over the damaged wheel, it would be easier to overcome him. But a hasty search revealed that he had lost his knife in the melee. And second thought gave him a better plan. After all, to get the letter was not everything. To know its destination would be important. He had no time to think further. The messenger was coming down the steps, not stealthily, but clattering, with the ring of nails in the heels of heavy boots.

Nikky flung his long length into the tonneau, and there crouched. It was dark enough to conceal him, but Nikky’s was a large body in a small place. However, the chauffeur only glanced at the car, kicked a tire with a practiced foot, and got in.

He headed for the open country. Very soon his passenger knew that he was in for a long ride possibly, a cold ride certainly. Within the city limits the car moved decorously, but when the suburbs were reached, the driver put on all his power. He drove carefully, too, as one who must make haste but cannot afford accident.

Nikky grew very uncomfortable. His long legs ached. The place between the shoulders where the concierge had landed his powerful blows throbbed and beat. Also he was puzzled, and he hated being puzzled. He was unarmed, too. He disliked that most of all. Generally speaking, he felt his position humiliating. He was a soldier, not a spy. His training had been to fight, not to hide and watch.

After a time he raised his head. He made out that they were going east, toward the mountains, and he cursed the luck that had left his revolver at home. Still he had no plan but to watch. Two hours’ ride, at their present rate, would take them over the border and into Karnia.

Nikky, although no thinker, was not a fool, and he knew rather better than most what dangers threatened the country from outside as well. Also, in the back of his impulsive head was a sort of dogged quality that was near to obstinacy. He had started this thing and he would see it through. And as the car approached the border, he began to realize that this was not of the Terrorists at home, but something sinister, abroad.

With a squealing of brakes the machine drew up at the frontier. Here was a chain across the highway, with two sets of guards. Long before they reached it, a sentry stepped into the road and waved his lantern.

Nikky burrowed lower into the car, and attempted to look like a rug. In the silence, while the sentry evidently examined a passport and flashed a lantern over the chauffeur, Nikky cursed the ticking of his watch, the beating of his own heart.

Then came a clanking as the chain dropped in the road. The car bumped over it, and halted again. The same formalities, this time by Karnian sentries. A bit more danger, too, for the captain in charge of the guard asked for matches, and dangled a careless hand over the side, within a few inches of Nikky’s head. Then the jerk following a hasty letting-in of the clutch, and they were off again.
