He raised a shade and window, then, and sat in the dark. The night was cloudy and very dark; and the lake was smooth with barely a ripple. Near at hand a steamer passed, blazing with lights, and further out he saw the mast-head light of some other steamer. The lake was still ice-locked at its northern end, and so the farther of these steamers, he knew, was bound to some southern Michigan port; the nearer was one of the Chicago-Milwaukee boats. For some moments after it had passed, the waves of its wake washed in and sounded on the shore at the foot of the bluff. Next Eaton made out the hum of a motor-car approaching the house. It was Avery, who evidently had been out and was now returning; the chauffeur spoke the name in his reply to some question as the car swung away to the garage. Eaton still sat in the dark. By degrees all noises ceased in the house, even in the servants' quarters. Twice Eaton leaned forward looking out of the window and found all quiet; but both times he settled back in his chair and waited. The wash of waves, as from a passing boat, sounded again on the shore. Eaton leaned nearer the window and stared out. There was no light in sight showing any boat; but the waves on the shore were distinct; indeed, they had been more distinct than those from the steamer. They must have been made by a large vessel or from a small ship close in and moving fast. The waves came in first on the north and swept south; Eaton strained his eyes and now saw a vague blur off to the south and within half a mile of shore--a boat without lights. If it had passed at high speed, it had stopped now. He watched this for some time; but he could make out no more, and soon he could not be sure even that the blur was there. He gazed at the south wing of the house; it was absolutely dark and quiet; the windows of the first floor were closed and the curtains drawn; but to-night there was no light in the room. The windows of the room on the second floor were open; Basil Santoine was undoubtedly asleep. Eaton gazed again at the lower room. Then in the dark he moved to the table where he had left his overcoat, and distributed in his pockets and within his clothing the articles he had brought; and now he felt again in the overcoat and brought out a short, strong bar of steel curved and flattened at one end--a "jimmy" for forcing the windows.
