Why, I wondered, did the captain persist in following this route? He could not intend to stop at Buffalo, in the midst of a crowd of boats and shipping of every kind. If he meant to leave the lake by water, there was only the Niagara River to follow; and its Falls would be impassable, even to such a machine as this. The only escape was by the Detroit River, and the “Terror” was constantly leaving that farther behind.

Then another idea occurred to me. Perhaps the captain was only waiting for night to return to the shore of the lake. There, the boat, changed to an automobile, would quickly cross the neighboring States. If I did not succeed in making my escape, during this passage across the land, all hope of regaining my liberty would be gone.

True, I might learn where this Master of the World hid himself. I might learn what no one had yet been able to discover, assuming always that he did not dispose of me at one time or another—and what I expected his “disposal” would be, is easily comprehended.

I knew the northeast end of Lake Erie well, having often visited that section of New York State which extends westward from Albany to Buffalo. Three years before, a police mission had led me to explore carefully the shores of the Niagara River, both above and below the cataract and its Suspension Bridge. I had visited the two principal islands between Buffalo and the little city of Niagara Falls, I had explored Navy Island and also Goat Island, which separates the American falls from those of the Canadian side.

Thus if an opportunity for flight presented itself, I should not find myself in an unknown district. But would this chance offer? And at heart, did I desire it, or would I seize upon it? What secrets still remained in this affair in which good fortune or was it evil fortune—had so closely entangled me!

On the other hand, I saw no real reason to suppose that there was any chance of my reaching the shores of the Niagara River. The “Terror” would surely not venture into this trap which had no exit. Probably she would not even go to the extremity of the lake.

Such were the thoughts that spun through my excited brain, while my eyes remained fixed upon the empty horizon.

And always one persistent question remained insolvable. Why had the captain written to me personally that threatening letter? Why had he spied upon me in Washington? What bond attached him to the Great Eyrie? There might indeed be subterranean canals which gave him passage to Lake Kirdall, but could he pierce the impenetrable fortress of the Eyrie? No! That was beyond him!

Toward four o’clock in the afternoon, reckoning by the speed of the “Terror” and her direction, I knew we must be approaching Buffalo; and indeed, its outlines began to show some fifteen miles ahead. During our passage, a few boats had been seen, but we had passed them at a long distance, a distance which our captain could easily keep as great as he pleased. Moreover, the “Terror” lay so low upon the water, that at even a mile away it would have been difficult to discover her.

Now, however, the hills encircling the end of Lake Erie, came within vision, beyond Buffalo, forming the sort of funnel by which Lake Erie pours its waters into the channel of the Niagara river. Some dunes rose on the right, groups of trees stood out here and there. In the distance, several freight steamers and fishing smacks appeared. The sky became spotted with trails of smoke, which were swept along by a light eastern breeze.
