"Should your conclusions be such as have been forced upon myself, further deliberation will yet be required with reference to the course to be pursued; a point on which, in such case, I confess myself almost equally unable to advise. Whether in a matter so surrounded with suspicion, it might not be well, in any event, to resist the claim, is certainly a question to be considered. On the other hand, even assuming the fullest proof of the terrible crimes involved, it is a matter calling for no less careful consideration, whether they would be found of a nature to bring the criminal within reach of the law. For the present, however, our concern is with the facts of the case, and ulterior questions had better be left on one side until that issue is decided, when, I conclude, I shall hear further from you on the subject. "In conclusion, I must trouble you with a few words on a point which seems to require explanation. I allude to the apparent prominence I have been compelled to afford to the workings of what is called 'Mesmeric Agency.' Those, indeed, who are so unfortunate as to be the victims of this delusion, would doubtless find in it a simple, though terrible solution of the mystery we are endeavouring to solve. But while frankly admitting that it was the passage from the 'Zoist Magazine,' quoted in the course of the evidence, which first suggested to my mind the only conclusion I have as yet been able to imagine, I beg at the outset most distinctly to state, that I would rather admit my own researches to have been baffled by an illusory coincidence, than lay myself open to the imputation of giving the slightest credit to that impudent imposture. We must not, however, forget that those whose lives have been passed in the deception of others, not unfrequently end by deceiving themselves. There is, therefore, nothing incredible in the idea that the Baron R** may have given sufficient credence to the statement of the 'Zoist,' above-mentioned, for the suggestion to his own mind of a design, which by the working of a true, though most mysterious, law of Nature, may really have been carried out. Such, at least, is the only theory by which I can attempt, in any way, to elucidate this otherwise unfathomable mystery.
