In these persons there appear to have been as few redeemable points as can be found in Human Nature, so far as such points may be traced in the kindly instincts and generous passions which do sometimes accompany the perpetration of great crimes, and, without excusing the individual, vindicate the species. Yet, on the other hand, their sanguinary wickedness was not the dull ferocity of brutes; it was accompanied with instruction and culture,—nay, it seemed to me, on studying their lives and pondering over their own letters, that through their cultivation itself we could arrive at the secret of the ruthless and atrocious pre- eminence in evil these Children of Night had attained; that here the monster vanished into the mortal, and the phenomena that seemed aberrations from Nature were explained.
I could not resist the temptation of reducing to a tale the materials which had so engrossed my interest and tasked my inquiries. And in this attempt, various incidental opportunities have occurred, if not of completely carrying out, still of incidentally illustrating, my earlier design,—of showing the influence of Mammon upon our most secret selves, of reproving the impatience which is engendered by a civilization that, with much of the good, brings all the evils of competition, and of tracing throughout, all the influences of early household life upon our subsequent conduct and career. In such incidental bearings the moral may doubtless be more obvious than in the delineation of the darker and rarer crime which forms the staple of my narrative. For in extraordinary guilt we are slow to recognize ordinary warnings,—we say to the peaceful conscience, "This concerns thee not!" whereas at each instance of familiar fault and commonplace error we own a direct and sensible admonition. Yet in the portraiture of gigantic crime, poets have rightly found their sphere and fulfilled their destiny of teachers. Those terrible truths which appall us in the guilt of Macbeth or the villany of Iago, have their moral uses not less than the popular infirmities of Tom Jones, or the every-day hypocrisy of Blifil. Incredible as it may seem, the crimes herein related took place within the last seventeen years. There has been no exaggeration as to their extent, no great departure from their details; the means employed, even that which seems most far- fetched,—the instrument of the poisoned ring,—have their foundation in literal facts. Nor have I much altered the social position of the criminals, nor in the least overrated their attainments and intelligence. In those more salient essentials which will most, perhaps, provoke the Reader's incredulous wonder, I narrate a history, not invent a fiction [These criminals were not, however, in actual life, as in the novel, intimates and accomplices. Their crimes were of similar character, effected by similar agencies, and committed at dates which embrace their several careers of guilt within the same period; but I have no authority to suppose that the one was known to the other.]. All that Romance which our own time affords is not more the romance than the philosophy of the time. Tragedy never quits the world,—it surrounds us everywhere. We have but to look, wakeful and vigilant, abroad, and from the age of Pelops to that of Borgia, the same crimes, though under different garbs, will stalk on our paths. Each age comprehends in itself specimens of every virtue and every vice which has ever inspired our love or mowed our horror.
