The young man had said nothing about old Mrs. Thomson. The detective had never even suspected any mystery in that quarter, though he was a man of mystery, and it was his business to suspect every thing. This was what he was thinking when he went back to the fire in his office, and stretched his hands over the blaze. Emotion of any kind somehow chills the physical frame; but when one of the detained clerks came to inform him of the patient brougham which waited outside, and which Sara, by reason of the cold, had sent for him, it was the opinion of the young man that Mr. Brownlow was beginning to age rapidly, and that he looked quite old that evening. But he did not look old; he looked, if any one had been there with eyes to see it, like a man for the first time in his life driven to bay. Some men come to that moment in their lives sooner, some later, some never at all. John Brownlow had been more than five-and-fifty years in the world, and yet he had never been driven to bay before. And he was so now; and except to stand out and resist, and keep his face to his enemies, he did not, in the suddenness of the occurrence, see as yet what he was to do. In the mean time, however, he had to stoop to ordinary necessities and get into his carriage and be driven home, through the white gleaming country which shone under the moonlight, carrying with him a curious perception of how different it would have been had the house in High Street been home--had he had nothing more to do than to go up to the old drawing-room, his mother’s drawing-room, and find Sara there; and eat his dinner where his father had eaten his, instead of this long drive to the great country-house, which was so much more costly and magnificent than any thing his forefathers knew; but then his father, what would he have thought of this complication? What would he have advised, had it been any client of his; nay, what, if it was a client, would Mr. Brownlow himself advise? These thoughts kept turning over in his mind half against his will as he lay back in the corner of the carriage and saw the ghostly trees glimmer past in their coating of snow. He was very late, and Sara was anxious about him; nay, even Jack was anxious, and had come down to the park gates to look out for the carriage, and also to ask how the little invalid was at Mrs. Swayne’s. Jack, having this curiosity in his mind, did not pay much attention to his father’s looks; but Sara, with a girl’s quick perception, saw there was something unusual in his face; and with her usual rapidity she leaped to the conclusion that the bank must have broken or the railway gone wrong of which she had dreamed in the morning. Thus they all met at the table with a great deal on their minds; and this day, which I have recorded with painstaking minuteness, in order that there may be no future doubt as to its importance in the history, came to an end with outward placidity but much internal perturbation--at least came to an end as
