“Vengeance!” cried Piero, furiously; “vengeance on the murderess of Carlotta!”
“Yes—vengeance shalt thou have, comrade,” returned the deep, sonorous voice of Stephano.
But scarcely were those words uttered, when the loud clanging of the bell struck up; and the abbess exclaimed joyfully, “We are saved! we are saved!”
CHAPTER XXXII.
THE MYSTERY OF THE CHAIR—THE CATASTROPHE.
The reader will recollect that when Flora Francatelli was released from the chair at the bottom of the pit or well, Sister Alba had led her along a narrow, dark passage communicating with the chamber of penitence.
In a small dome-like cavity, hollowed out of the roof of this passage, hung a large bell; and in a cell opening from the side of the passage immediately beneath the dome, dwelt an old nun, who, for some dreadful misdeed committed in her youth, had voluntarily consigned herself to the convent of the Carmelites, and, having passed through the ordeal of the chamber of penitence, had accepted the office of sextoness in that department of the establishment.
It was her duty to keep the chamber of penitence clean, maintain tapers constantly burning before the altar, supply also the cells of the penitents themselves with lights, and toll the bell whenever occasion required. She it was who had visited Flora’s cell the first night of her arrival at the convent, to renew the taper that burnt before her crucifix, and to exchange the maiden’s attire for the conventual garb.
This old nun it was, then, who suddenly tolled the bell, at the moment when Piero and Stephano were menacing the abbess and Sister Alba with their vengeance, and when the Marquis of Orsini was bearing away Flora to the robbers’ hold, that she might have the companionship of Giulia.
The way in which the old nun rang the bell was such that the inmates of the convent would perceive it to be an alarm; and moreover, so sudden was its startling clang, that Stephano and Piero abandoned their hold upon the abbess and Sister Alba, and retreated a few paces, uncertain how to act; hence the exclamation of the superior of the convent, “We are saved! we are saved!”
But little did that stern, imperious woman know of the desperate characters of those with whom she had now to deal. Ashamed of their momentary hesitation, Stephano and Piero rushed on the abbess and Sister Alba, and dragged them, in spite of their deafening screams, into that fatal cell, where they threw them headlong over the lifeless corpse of their victim.
