“And by accustoming her to that poison, you have endeavored to neutralize the effect of a similar poison?” Noirtier’s joy continued. “And you have succeeded,” exclaimed d’Avrigny. “Without that precaution Valentine would have died before assistance could have been procured. The dose has been excessive, but she has only been shaken by it; and this time, at any rate, Valentine will not die.”

A superhuman joy expanded the old man’s eyes, which were raised towards heaven with an expression of infinite gratitude. At this moment Villefort returned.

“Here, doctor,” said he, “is what you sent me for.”

“Was this prepared in your presence?”

“Yes,” replied the procureur.

“Have you not let it go out of your hands?”

“No.”

D’Avrigny took the bottle, poured some drops of the mixture it contained in the hollow of his hand, and swallowed them.

“Well,” said he, “let us go to Valentine; I will give instructions to everyone, and you, M. de Villefort, will yourself see that no one deviates from them.”
