And yet, to the walls of the mind that he was trying so hard to cleanse from prejudice and prepossession--to school indeed to an inhuman fairness--there clung small circumstances and smaller details which could influence no one else, which would not constitute evidence before any tribunal, but which weighed more with Langholm himself than all the points arrayed in his note-book with so much primness and precision. There was Rachel's vain appeal to her husband, "Find out who _is_ guilty if you want people to believe that I am not." Why should so natural a petition have been made in vain, to a husband who after all had shown some solicitude for his wife's honor, and who had the means to employ the best detective talent in the world? Langholm could only conceive one reason: there was nothing for the husband to find out, but everything for him to hide. Langholm remembered the wide-eyed way in which Steel had looked at his wife before replying, and the man's embarrassment grew automatically in his mind. His lips had indeed shut very tight, but unconscious exaggeration made them tremble first. And then the fellow's manner to himself, his defiant taunts, his final challenge! Langholm was not sorry to remember the last; it relieved him from the moral incubus of the clandestine and the underhand; it bid him go on and do his worst; it set his eyes upon the issue as between himself and Steel, and it shut them to the final possibilities as touching the woman in the case. So Langholm came back from sultry London to a world of smoke and rain, with furnaces flaring through the blurred windows, and the soot laid with the dust in one of the grimiest towns in the island; but he soon shook both from his feet, and doubled back upon the local line to a rural station within a mile and a half of his cottage. This distance he walked by muddy ways, through the peculiarly humid atmosphere created by a sky that has rained itself out and an earth that can hold no more, and came finally to his dripping garden by the wicket at the back of the cottage. There he stood to inhale the fine earthy fragrance which atoned somewhat for a rather desolate scene. The roses were all washed away. William Allen Richardson clung here and there, in the shelter of the southern eaves, but he was far past his prime, and had better have perished with the exposed beauties on the tiny trees. The soaking foliage had a bluish tinge; the glimpse of wooded upland, across the valley through the gap in the hedge of Penzance briers, lay colorless and indistinct as a faded print from an imperfect negative. A footstep crunched the wet gravel at Langholm's back. "Thank God you've got back, sir!" cried a Yorkshire voice in devout accents; and Langholm, turning, met the troubled face and tired eyes of the woman next door, who kept house for him while living in her own.
