Trevelyan was left alone at Turin when Mr Glascock went on to Florence with his fair American friends. It was imperatively necessary that he should remain at Turin, though he had no business there of any kind whatever, and did not know a single person in the city. And of all towns in Italy Turin has perhaps less of attraction to offer to the solitary visitor than any other. It is new and parallelogrammatic as an American town is very cold in cold weather, very hot in hot weather, and now that it has been robbed of its life as a capital is as dull and uninteresting as though it were German or English. There is the Armoury, and the river Po, and a good hotel. But what are these things to a man who is forced to live alone in a place for four days, or perhaps a week? Trevelyan was bound to remain at Turin till he should hear from Bozzle. No one but Bozzle knew his address; and he could do nothing till Bozzle should have communicated to him tidings of what was being done at St. Diddulph’s.

There is perhaps no great social question so imperfectly understood among us at the present day as that which refers to the line which divides sanity from insanity. That this man is sane and that other unfortunately mad we do know well enough; and we know also that one man may be subject to various hallucinations — may fancy himself to be a teapot, or what not — and yet be in such a condition of mind as to call for no intervention either on behalf of his friends, or of the law; while another may be in possession of intellectual faculties capable of lucid exertion for the highest purposes, and yet be so mad that bodily restraint upon him is indispensable. We know that the sane man is responsible for what he does, and that the insane man is irresponsible; but we do not know, we only guess wildly, at the state of mind of those who now and again act like madmen, though no court or council of experts has declared them to be mad. The bias of the public mind is to press heavily on such men till the law attempts to touch them, as though they were thoroughly responsible; and then, when the law interferes, to screen them as though they were altogether irresponsible. The same juryman who would find a man mad who has murdered a young woman, would in private life express a desire that the same young man should be hung, crucified, or skinned alive, if he had moodily and without reason broken faith to the young woman in lieu of killing her. Now Trevelyan was, in truth, mad on the subject of his wife’s alleged infidelity. He had abandoned everything that he valued in the world, and had made himself wretched in every affair of life, because he could not submit to acknowledge to himself the possibility of error on his own part. For that, in truth, was the condition of his mind. He had never hitherto believed that she had been false to her vow, and had sinned against him irredeemably; but he had thought that in her regard for another man she had slighted him; and, so thinking, he had subjected her to a severity of rebuke which no high-spirited woman could have borne. His wife had not tried to bear it, in her indignation had not striven to cure the evil. Then had come his resolution that she should submit, or part from him; and, having so resolved, nothing could shake him. Though every friend he possessed was now against him including even Lady Milborough he was certain that he was right. Had not his wife sworn to obey him, and was not her whole conduct one tissue of disobedience? Would not the man who submitted to this find himself driven to submit to things worse? Let her own her fault, let her submit, and then she should come back to him.

He had not considered, when his resolutions to this effect were first forming themselves, that a separation between a man and his wife once effected cannot be annulled, and as it were cured, so as to leave no cicatrice behind. Gradually, as he spent day after day in thinking on this one subject, he came to feel that even were his wife to submit, to own her fault humbly, and to come back to him, this very coming back would in itself be a new wound. Could he go out again with his wife on his arm to the houses of those who knew that he had repudiated her because of her friendship with another man? Could he open again that house in Curzon Street, and let things go on quietly as they had gone before? He told himself that it was impossible, that he and she were ineffably disgraced, that, if reunited, they must live buried out of sight in some remote distance. And he told himself, also, that he could never be with her again night or day without thinking of the separation. His happiness had been shipwrecked.

Then he had put himself into the hands of Mr Bozzle, and Mr Bozzle had taught him that women very often do go astray. Mr Bozzle’s idea of female virtue was not high, and he had opportunities of implanting his idea on his client’s mind. Trevelyan hated the man. He was filled with disgust by Bozzle’s words, and was made miserable by Bozzle’s presence. Yet he came gradually to believe in Bozzle. Bozzle alone believed in him. There were none but Bozzle who did not bid him to submit himself to his disobedient wife. And then, as he came to believe in Bozzle, he grew to be more and more assured that no one but Bozzle could tell him facts. His chivalry, and love, and sense of woman’s honour, with something of manly pride on his own part, so he told himself, had taught him to believe it to be impossible that his wife should have sinned. Bozzle, who knew the world, thought otherwise. Bozzle, who had no interest in the matter, one way or the ............
