And forasmuch as crouching under the lee of a hauled-up boat on a night when it blew cold and strong, and when the weather was varied with blasts of hail at times, might be wearisome to amateurs, the reporter closed with the recommendation that the two gentlemen should remain, for a while at any rate, in their present quarters, which were weather-tight and warm.
They were not inclined to dispute this recommendation, but they wanted to know where they could join the watchers when so disposed.

Rather than trust to a verbal description of the place, which might mislead, Eugene (with a less weighty sense of personal trouble on him than he usually had) would go out with Mr Inspector, note the spot, and come back.
On the shelving bank of the river, among the slimy stones of a causeway--not the special causeway of the Six Jolly Fellowships, which had a landing-place of its own, but another, a little removed, and very near to the old windmill which was the denounced man's dwelling-place--were a few boats; some, moored and already beginning to float; others, hauled up above the reach of the tide.

Under one of these latter, Eugene's companion disappeared.

And when Eugene had observed its position with reference to the other boats, and had made sure that he could not miss it, he turned his eyes upon the building where, as he had been told, the lonely girl with the dark hair sat by the fire.
He could see the light of the fire shining through the window.

Perhaps it drew him on to look in.
