Having examined the knots in the rope, which were very well done, indeed, and having gagged the chauffeur securely, Nikky prepared to go. In his goggles, with the low-visored cap and fur coat, he looked not unlike his late companion. But he had a jaunty step as he walked toward the car, a bit of swagger that covered, perhaps, just a trifle of uneasiness.

For Nikky now knew his destination, knew that he was bound on perilous work, and that the chances of his returning were about fifty-fifty, or rather less.

Nevertheless, he was apparently quite calm as he examined the car. He would have chosen, perhaps, a less perilous place to attempt its mysteries, but needs must. He climbed in, and released the brakes. Then, with great caution, and considerable noise, he worked it away from the brink of the chasm, and started off.

He did not know his way. Over the mountains it was plain enough, for there was but one road. After he descended into the plain of Karnia, however, it became difficult. Sign-posts were few and not explicit. But at last he found the railroad, which he knew well—that railroad without objective, save as it would serve to move troops toward the border. After that Nikky found it easier.

But, with his course assured, other difficulties presented themselves. To take the letter to those who would receive it was one thing. But to deliver it, with all that it might contain, was another. He was not brilliant, was Nikky. Only brave and simple of heart, and unversed in the ways of darkness.

If, now, he could open the letter and remove it, substituting—well, what could he substitute? There were cigarette papers in his pocket. Trust Nikky for that. But how to make the exchange?

Nikky pondered. To cut the side of the envelope presented itself. But it was not good enough. The best is none too good when one’s life is at stake.

The engine was boiling hard, a dull roaring under the hood that threatened trouble. He drew up beside the road and took off the water-cap. Then he whistled. Why, of course! Had it not been done from time immemorial, this steaming of letters? He examined it. It bore no incriminating seal.

He held the envelope over the water-cap, and was boyishly pleased to feel the flap loosen. After all, things were easy enough if one used one’s brains. He rather regretted using almost all of his cigarette papers, of course. He had, perhaps, never heard of the drop of nicotine on the tongue of a dog.

As for the letter itself, he put it, without even glancing at it, into his cap, under the lining. Then he sealed the envelope again and dried it against one of the lamps. It looked, he reflected, as good as new.
