All through the first three winter months, twice a day, Caroline and the stranger thus saw each other for so long as it took him to traverse the piece of road that lay along the length of the door and three windows of the house. Day after day this brief interview had the hue of friendly sympathy which at last had acquired a sort of fraternal kindness. Caroline and the stranger seemed to understand each other from the first; and then, by dint of scrutinizing each other’s faces, they learned to know them well. Ere long it came to be, as it were, a visit that the Unknown owed to Caroline; if by any chance her Gentleman in Black went by without bestowing on her the half-smile of his expressive lips, or the cordial glance of his brown eyes, something was missing to her all day. She felt as an old man does to whom the daily study of a newspaper is such an indispensable pleasure that on the day after any great holiday he wanders about quite lost, and seeking, as much out of vagueness as for want of patience, the sheet by which he cheats an hour of life. But these brief meetings had the charm of intimate friendliness, quite as much for the stranger as for Caroline. The girl could no more hide a vexation, a grief, or some slight ailment from the keen eye of her appreciative friend than he could conceal anxiety from hers. “He must have had some trouble yesterday,” was the thought that constantly arose in the embroideress’ mind as she saw some change in the features of the “Black Gentleman.” “Oh, he has been working too hard!” was a reflection due to another shade of expression which Caroline could discern. The stranger, on his part, could guess when the girl had spent Sunday in finishing a dress, and he felt an interest in the pattern. As quarter-day came near he could see that her pretty face was clouded by anxiety, and he could guess when Caroline had sat up late at work; but above all, he noted how the gloomy thoughts that dimmed the cheerful and delicate features of her young face gradually vanished by degrees as their acquaintance ripened. When winter had killed the climbers and plants of her window garden, and the window was kept closed, it was not without a smile of gentle amusement that the stranger observed the concentration of the light within, just at the level of Caroline’s head. The very small fire and the frosty red of the two women’s faces betrayed the poverty of their home; but if ever his own countenance expressed regretful compassion, the girl proudly met it with assumed cheerfulness.
