She had made the round of the garden, which was a long piece of ground, more than half of it grass, and of a very woodland aspect for anything so near London, and was about passing the side of the house on her way back, when Janet’s attention was suddenly roused in a very extraordinary way. The house was square, of the commonest comfortable form, but on the western side there had been built on to it, at some previous period, a wing, which projected in front, making a gable, and slightly outpassing the _corps du logis_. This wing, however, was not, so far as Janet knew, ever used at all. If used, it was as a lodging or workshop, whatever his employment might be, for the mysterious Vicars, who yet was not mysterious at all--the man-servant of whom more had been seen since Dolff’s return home, and who, Janet had vaguely understood, lived in some corner of the house, carrying on his own avocations, whatever they were, but at hand when he was wanted for any special service--a privilege given by the kindness of Mrs. Harwood to an old servant, but also a convenience to herself. It was after Janet had seen this personage carrying through an open door, which had all the appearance at other times of being hermetically closed, a tray covered with dainties, that Mrs. Harwood herself had explained the position of Vicars to the governess, thus settling the question. Nothing could possibly be more uninhabited, more shut-up and empty, than the wing. It had two long windows on the upper floor, facing the garden, which were so grown over with ivy that it was clearly apparent no light could enter, or human uses be served by them. The ivy was carefully trained, and perhaps a little thinner than usual at this time of the year. As Janet came opposite the windows, something--she could not tell what--made her look up. The moonlight was streaming full upon them, showing white crevices and reflections in the half-covered window-panes which never showed by day. She stopped short, struck by an alarm and horror which seemed to freeze the blood in her veins. At the nearest window, in an opening made by the curvature of a great ivy branch half denuded of leaves, there appeared to her the face of an old man with white hair and a long, white beard--a white image so like the moonlight that, after the first dreadful realization of what she saw as a face, Janet, in her terror, tried to persuade herself that it was only some effect of the white light shining upon the panes, which were covered by dust and the droppings of the heavy foliage. If she had hurried away then, flying indoors, as was her first impulse, no doubt she would have been able to persuade herself that this was the case. But she was, on the other hand, too much frightened, too much excited, to fly. She stood still, scarcely able to draw her breath.
