After that Mr. Brownlow went away. He had got no information, no satisfaction, and yet he had made no discovery, which was a kind of negative comfort in its way; but it was clear that his mother-in-law, though she made so much use of Phœbe Thomson’s name, was utterly unable to give him any assistance either in discovering the real Phœbe Thomson or in exposing any false pretender. He went across the market place over the crisp snow in the sunshine with all his faculties, as it were, crisped and sharpened like the air he breathed. This was all the effect as yet which the frosts of age had upon him. He had all his powers unimpaired, and more entirely serviceable and under command than ever they were. He could trust himself not to betray himself, to keep counsel, and act with deliberation, and do nothing hastily. Thus, though his enemies were as yet unknown and unrecognized, and consequently all the more dangerous, he had confidence in his own army of defense, which was a great matter. He returned to his office, and to his business, and was as clearheaded and self-possessed, and capable of paying attention to the affairs of his clients, as if he had nothing particular in his own to occupy him. And the only help he got from circumstances was that which was given him by the frost, which had happily interfered this day of all others to detain Jack. Jack was not his father’s favorite child; he was not, as Sara was, the apple of John Brownlow’s eye; and yet the lawyer appreciated, and did justice to, as well as loved, his son, in a just and natural way. He felt that Jack’s quick eye would have found out that there was something more than usual going on. He knew that his visit to Mrs. Fennell and his unexplained conference with the man of mystery would not have been passed over by Jack without notice; and at the young man’s hasty, impetuous time of life, prudence was not to be expected or even desired. If Jack thought it possible that Phœbe Thomson was to be found within a hundred miles, no doubt he would make off without a moment’s thought and hunt her up, and put his own fortune, and, what was more, Sara’s, eagerly into her hands. This was what Jack would do, and Mr. Brownlow was glad in his heart that Jack would be sure to do it; but yet it might be a very different course which he himself, after much thought and consideration, might think it best to take.
