What share in the production of this decision Lady H---- may have had I do not know, but I have a notion that she had much to do with it; for it is certain beyond all doubt that the loss of her jewelry preyed upon her spirits, and exasperated her to the last pitch of intensity. Being rather shrewishly inclined, she would, I verily believe, have inflicted summary vengeance on the stoutest of the thieves if she could have clutched him. Lord H----'s solicitors were somewhat annoyed at the failure of the police in the discovery of the criminals. They communicated with me upon the subject, and I at length was employed. It was a teasing and difficult job. It gave me ten times more trouble than many a greater and more important business. Yet, having undertaken it, I was determined to go through with it. I would not, I felt, be baffled. For a long while I could obtain no clue. At length I did get a scent of my prey, and from that moment the result was certain, although it could only be overtaken by a circuitous and uneven track. I at length hunted down the principal delinquent. The whole robbery had been effected by one man and one woman. The woman fled as soon as the man was arrested. I might have secured her before, but in doing so must have lost the man. Her arrest would have given him notice of his peril; and, in truth, I was almost careless about the female's escape if I could catch her companion. Lord H---- was more exasperated than ever when he ascertained who the criminal was; although he assured his solicitors, as they informed me, that he had not the slightest knowledge of the man, nor did he suppose the delinquent had any knowledge of him beyond that which all thieves of London might have in common of a nobleman. I suspected that some mysterious cause inspired this desire for vengeance in his lordship, besides the natural influence of his loss upon his mind. That was sufficient to account for much revengefulness, but it did not appear to me an adequate motive for the sudden increase of such an emotion since the disclosure of the identity of the criminal. I do not, however, know that my suspicions were correct. It is possible that they were incorrect. The offender was brought before the magistrate, in the usual course, and remand upon remand was applied for and obtained. The prisoner's attorney resisted the application with all his argumentative power and force of advocacy, but in vain. The prosecution was thought by the bench to be entitled to every opportunity for discovering their property, and so involving the prisoner in the evidence of his guilt as to render his escape through the meshes of the law impossible. At length the case was brought home with sufficient clearness to the prisoner, not only to warrant his committal for trial, but to secure his conviction when that trial took place. He was accordingly committed.
