Du Bosse was interrupted in his narrative by the counsel of the Marquis, who contended that the circumstances alleged tending to criminate his client, the proceeding was both irrelevant and illegal. He was answered that it was not irrelevant, and therefore not illegal; for that the circumstances which threw light upon the character of the Marquis, affected his evidence against La Motte. Du Bosse was suffered to proceed.
D'Aunoy then said that the Marquis had ordered him to dispatch her, but that, as he had been used to see her from her infancy, he could not find in his heart to do it, and wrote to tell him so. The Marquis then commanded him to find those who would, and this was the business for which he wanted us. My brother and I were not so wicked as this came to, and so we told D'Aunoy; and I could not help asking why the Marquis resolved to murder his own child rather than expose her mother to the risque of suffering death. He said the Marquis had never seen his child and that, therefore, it could not be supposed he felt much kindness towards it, and still less that he could love it better than he loved its mother.
Du Bosse proceeded to relate how much he and his brother had endeavoured to soften the heart of D'Aunoy towards the Marquis's daughter, and that they prevailed with him to write again and plead for her. D'Aunoy went to Paris to await the answer, leaving them and the young girl at the house on the heath, where the former had consented to remain, seemingly for the purpose of executing the orders they might receive, but really with a design to save the unhappy victim from the sacrifice.
It is probable that Du Bosse, in this instance, gave a false account of his motive; since, if he was really guilty of an intention so atrocious as that of murder, he would naturally endeavour to conceal it. However this might be, he affirmed, that on the night of the twenty-sixth of April, he received an order from D'Aunoy for the destruction of the girl, whom he had afterwards delivered into the hands of La Motte.
La Motte listened to this relation in astonishment; when he knew that Adeline was the daughter of the Marquis, and remembered the crime to which he had once devoted her, his frame thrilled with horror. He now took up the story, and added an account of what had passed at the abbey between the Marquis and himself, concerning a design of the former upon the life of Adeline, and urged, as a proof of the present prosecution originating in malice, that it had commenced immediately after he had effected her escape from the Marquis. He concluded, however, with saying, that as the Marquis had immediately sent his people in pursuit of her, it was possible she might yet have fallen a victim to his vengeance.
Here the Marquis's counsel again interfered, and their objections were again overruled by the court. The uncommon degree of emotion which his countenance betrayed during the narrations of Du Bosse and De La Motte was generally observed. The court suspended the sentence of the latter, ordered that the Marquis should be put under immediate arrest, and that Adeline (the name given by her fostermother) and Jean D'Aunoy should be sought for.
The Marquis was accordingly seized at the suit of the crown, and put under confinement till Adeline should appear, or proof could be obtained that she died by his order; and till D'Aunoy should confirm or destroy the evidence of De La Motte.
Madame, who at length obtained intelligence of her son's residence from the town where he was formerly stationed, had acquainted him with his father's situation, and the proceedings of the trial; and as she believed that Adeline, if she had been so fortunate as to escape the Marquis's pursuit, was still in Savoy, she desired Louis would obtain leave of absence, and bring her to Paris, where her immediate presence was requisite to substantiate the evidence, and probably to save the life of La Motte.
On the receipt of her letter, which happened on the morning appointed for the execution of Theodore, Louis went immediately to the commanding officer to petition for a respite till the king's further pleasure should be known. He founded his plea on the arrest of the Marquis, and showed the letter he had just received. The commanding officer readily granted a reprieve; and Louis, who, on the arrival of this letter had forborne to communicate its contents to Theodore, lest it should torture him with false hope, now hastened to him with this comfortable news.
