If those who are interested in the subject will carefully read what I have quoted, they will not be able to detect any word or hint from my father that it was upon the Mystery alone that he relied for the interest and originality of his idea. The originality was to be shown, as he tells us, in what we may call the psychological description the murderer gives us of his temptations, temperament, and character, as if told by another; and my father speaks openly of the ring to Mr. Forster. Moreover, he refers to it often in his story, and we all recognise it, whatever our other convictions may be, as the instrument by which Jasper’s wickedness and guilt are to be established in the end. I do not mean to imply that the mystery itself had no strong hold on my father’s imagination; but, greatly as he was interested in the intricacies of that tangled skein, the information he voluntarily gave to Mr. Forster, from whom he had withheld nothing for thirty-three years, certainly points to the fact that he was quite as deeply fascinated and absorbed in the study of the criminal Jasper, as in the dark and sinister crime that has given the book its title. And he also speaks to Mr. Forster of the murder of a nephew by an uncle. He does not say that he is uncertain whether he shall save the nephew, but has evidently made up his mind that the crime is to be committed. And so he told his plot to Mr. Forster, as he had been accustomed to tell his plots for years past; and those who knew him must feel it impossible to believe that in this, the last year of his life, he should suddenly become underhand, and we might say treacherous, to his old friend, by inventing for his private edification a plot that he had no intention of carrying into execution. This is incredible, and the nature of the friendship that existed between Mr. Forster and himself makes the idea unworthy of consideration.
