Reader, cast back your eye to that passage in this history when Lucretia Clavering took down the volume from the niche in the tapestried chamber at Laughton, and numbered, in thought, the hours left to her uncle’s life. Look back on the ungrateful thought; behold how it has swelled and ripened into the guilty deed! There, in that box, Death guards his treasure crypt. There, all the science of Hades numbers its murderous inventions. As she searched for the ingredients her design had pre-selected, something heavier than those small packets she deranged fell to the bottom of the box with a low and hollow sound. She started at the noise, and then smiled, in scorn of her momentary fear, as she took up the ring that had occasioned the sound,—a ring plain and solid, like those used as signets in the Middle Ages, with a large dull opal in the centre. What secret could that bauble have in common with its ghastly companions in Death’s crypt? This had been found amongst Olivier’s papers; a note in that precious manuscript, which had given to the hands of his successors the keys of the grave, had discovered the mystery of its uses. By the pressure of the hand, at the touch of a concealed spring, a barbed point flew forth steeped in venom more deadly than the Indian extracts from the bag of the cobar de capello,—a venom to which no antidote is known, which no test can detect. It corrupts the whole mass of the blood; it mounts in frenzy and fire to the brain; it rends the soul from the body in spasm and convulsion. But examine the dead, and how divine the effect of the cause! How go back to the records of the Borgias, and amidst all the scepticisms of times in which, happily, such arts are unknown, unsuspected, learn from the hero of Machiavel how a clasp of the hand can get rid of a foe! Easier and more natural to point to the living puncture in the skin, and the swollen flesh round it, and dilate on the danger a rusty nail—nay, a pin—can engender when the humours are peccant and the blood is impure! The fabrication of that bauble, the discovery of Borgia’s device, was the masterpiece in the science of Dalibard,—a curious and philosophical triumph of research, hitherto unused by its inventor and his heirs; for that casket is rich in the choice of more gentle materials: but the use yet may come. As she gazed on the ring, there was a complacent and proud expression on Lucretia’s face.

“Dumb token of Caesar Borgia,” she murmured,—“him of the wisest head and the boldest hand that ever grasped at empire, whom Machiavel, the virtuous, rightly praised as the model of accomplished ambition! Why should I falter in the paths which he trod with his royal step, only because my goal is not a throne? Every circle is as complete in itself, whether rounding a globule or a star. Why groan in the belief that the mind defiles itself by the darkness through which it glides on its object, or the mire through which it ascends to the hill? Murderer as he was, poisoner, and fratricide, did blood clog his intellect, or crime impoverish the luxury of his genius? Was his verse less melodious [It is well known that Caesar Borgia was both a munificent patron and an exquisite appreciator of art; well known also are his powers of persuasion but the general reader may not, perhaps, be acquainted with the fact that this terrible criminal was also a poet], or his love of art less intense, or his eloquence less persuasive, because he sought to remove every barrier, revenge every wrong, crush every foe?”

In the wondrous corruption to which her mind had descended, thus murmured Lucretia. Intellect had been so long made her sole god that the very monster of history was lifted to her reverence by his ruthless intellect alone,—lifted in that mood of feverish excitement when conscience, often less silenced, lay crushed, under the load of the deed to come, into an example and a guide.

Though at times, when looking back, oppressed by the blackest despair, no remorse of the past ever weakened those nerves when the Hour called up its demon, and the Will ruled the rest of the human being as a machine.

She replaced the ring, she reclosed the casket, relocked its depository; then passed again into the adjoining chamber.

A few minutes afterwards, and the dim light that stole from the heavens (in which the moon was partially overcast) through the casement on the staircase rested on a shapeless figure robed in black from head to foot,—a figure so obscure and undefinable in outline, so suited to the gloom in its hue, so stealthy and rapid in its movements, that had you started from sleep and seen it on your floor, you would perforce have deemed that your fancy had befooled you!

Thus darkly, through the darkness, went the Poisoner to her prey.

CHAPTER XVIII. RETROSPECT.

We have now arrived at that stage in this history when it is necessary to look back on the interval in Lucretia’s life,—between the death of Dalibard, and her reintroduction in the second portion of our tale.
