Callon could not quite keep the relief which he felt out of his eyes or the smile from his lips. Pamela noticed the change with amusement. She was not in the mind to spare him uneasiness, and she said, looking at the wall above the mantelpiece--
"This is an old mirror, don't you think? From what period would you date it?"
Callon's thoughts had been so intent upon the stairs that he had paid no heed to the ornaments above the mantelshelf. Now, however, he took note of them with a face grown at once anxious. The mirror was of an oval shape and framed in gold. Under the pretence of admiring it, he moved and stood behind Pamela, looking into the mirror over her shoulder, seeing what she could see, and wondering how much she had seen. He was to some extent relieved. The stairs were ill-lighted, the panelling of the wall dark mahogany; moreover, the stairs bent round into the hall just below the level of the roof, and at the bend the lady on the stairs had stopped. Pamela could not have seen her face. Pamela, indeed, had seen nothing more than a black satin slipper arrested in the act of taking a step, and a black gown with some touches of red at the waist. She had, however, noticed the attitude of the wearer of the dress when the warning voice had brought her to a stop. The lady had stooped down and had cautiously peered into the hall. In this attitude she had been able to see, and yet had avoided being seen.
Pamela, however, did not relieve Mr. Callon of his suspense. She walked into the drawing-room and waited, with an amused curiosity, for the appearance of the black dress. It was long in coming, however. Pamela had no doubt that it would come last, and in a hurry, as though its wearer had been late in dressing. But Pamela was wrong. Millicent Stretton came into the room dressed in a frock of white lace, and at once dinner was announced. Pamela turned to Frances Millingham with a startled face--
"Are we all here?"
Frances Millingham looked round.
"Yes;" and Lord Millingham at that moment offered his arm to Pamela. As she took it, she looked at Millicent, who was just rising from her chair. Millicent was wearing with her white dress black shoes and stockings. She might be wearing them deliberately, of course; on the other hand, she might be wearing them because she had not had time to change them. It was Millicent, certainly, who had come down last. "I beg your pardon, Miss Mardale," Callon had said, and it was upon the "Miss Mardale" that his voice had risen. The emphasis of his warning had been laid upon the name.
As she placed her hand on her host's arm, Pamela said--
"It was very kind of Frances to ask Millie Stretton here."
"Oh no," Lord Millingham replied. "You see, Frances knew her. We all knew, besides, that she is a great friend of yours."
