Thus it came that the garden was made a little larger, and two rooms were added to the house, with other modest improvements, to accommodate Auntie Sue's grown-up boys and girls when they came to visit her. But never was there a hired servant, so that her guests must do their own household tasks, because, Auntie Sue said, that was good for them and mostly what they needed. It should also be said here that among her many pupils who lived beyond the sky-line of the far, blue hills, not one knew more of the real secret of Auntie Sue's life and character than did the Ozark mountaineers of the Elbow Rock district, among whom she had chosen to pass the evening of her day. Then came one who learned the secret. He learned--but that is my story. I must not tell the secret here. CHAPTER II. THE MAN IN THE DARK. A man stood at a window, looking out into the night. There was no light in the room. The stars were hidden behind a thick curtain of sullen clouds. The house was a wretchedly constructed, long-neglected building of a type common to those old river towns that in their many years of uselessness have lost all civic pride, and in their own resultant squalor and filth have buried their self-respect. A dingy, scarcely legible sign over the treacherous board walk, in front, by the sickly light of a smoke-grimed kerosene lantern, announced that the place was a hotel. Dark as it was, the man at the window could see the river. The trees that lined the bank opposite the town were mere ghostly shadows against the gloomy masses of the low hills that rose from the water's edge, indistinct, mysterious, and unreal, into the threatening sky. The higher mountains that reared their crests beyond the hills were invisible. The stream itself swept sullenly through the night,--a resistless flood of dismal power, as if, turbid with wrecked souls, with the lost hopes and ruined dreams of men, it was fit only to bear vessels freighted with sorrow, misfortune, and despair. The manner of the man at the window was as if some woeful spirit of the melancholy scene were calling him. With head bowed, and face turned a little to one side, he listened intently as one listens to voices that are muffled and indistinct. He pressed his face close to the glass, and with straining eyes tried to see more clearly the ghostly trees, the sombre hills, and the gloomy river. Three times he turned from the window to pace to and fro in the darkened room, and every time his steps brought him again to the casement, as if in obedience to some insistent voice that summoned him. The fourth time, he turned from the window more quickly, with a gesture of assenting decision.
