This day, the 8th June, passed in the most perfect calm for the inhabitants of Donnay. Mme. Acquet did not leave La Bijude. In the afternoon a tanner of Placy, called Brazard, passed the house and called to Hébert whom he saw in the garden. He told him that when he got up that morning he had found four horses tied to his hedge. The gendarmes from Langannerie had come and claimed them saying "they belonged to the Falaise-Caen coach which had been attacked in the night by Chouans." Hébert was much astonished; Mme. Acquet did not believe it; but the report spread and by evening the news was known to the whole village.
Acquet had remained invisible for a month; his instinct of hatred and some information slyly obtained, warned him that his wife was working her own ruin, and he would do nothing to stop her good work. Some days before, Aumont, his gardener, had remarked one morning that the dew was brushed off the grass of the lawn, and showed footsteps leading to the cellar of the château, but Acquet did not seem to attach any importance to these facts.
He learned from his servant of the robbery of the coach. The next day, Redet, the butcher of Meslay, said that ten days previously, when he was passing the ruins of the Abbey of Val "his mare shied, frightened at the sight of seven or eight men, who came out from behind a hedge;" they asked him the way to Rouen. Redet, without answering, made off, and as he told every one of this encounter, Hébert the liegeman of Mme. de Combray, had instantly begged him not to spread it about. If Acquet had retained any doubt, this would have satisfied him. He hurried to Meslay to consult with his friend Darthenay, and the next day, he wrote to the commandant of gendarmerie inviting him to search the Château of Donnay.
The visit took place on Friday, 12th June, and was conducted by Captain Pinteville. Acquet offered to guide him, and the search brought some singular discoveries. Certain doors of this great house, long abandoned, were found with strong locks recently put on; others were nailed up and had to be broken in. "In a dark, retired loft that it was difficult to enter" (Acquet conducted the gendarmes) "a pile of hay still retained the impress of six men who had slept on it"; some fresh bones, scraps of bread and meat, and the dirt bore witness that the band had lived there; some sheets of paper belonging to a memoir printed by Hely de Bonnœil, brother of Mme. Acquet were rolled into cartridges and hidden in a corner under the tiles. They also found the sacks that the Buquets had hidden there after the theft; in the floor of the cellar a hole, "two and a half feet square, and of the same depth had been dug to hold the money;" they had taken the precaution to tear up the flooring above so that the depôt could be watched from there. The idea of hiding the treasure here had been abandoned, as we know, in favour of Buquets'; but the discovery was important and Pinteville drew up a report of it.
But things went no further. What suspicion could attach to the owners of Donnay? The brigands, it is true, had made use of their house, but there were no grounds for an accusation of complicity in that. Neither Pinteville nor Caffarelli, who transmitted the report to the minister, thought of pushing their enquiries any further.
Fouché knew no more about it, but he thought that the affair was being feebly conducted. It seemed evident that the attempt at Quesnay would swell the already long list of thefts of public funds, by those who would forever remain unpunished. Réal, instinctively scenting d'Aché in the business, remembered Captain Manginot who at the time of Georges Cadoudal's plot, had succeeded in tracing the stages of the conspirators between Biville and Paris, and to whom they owed the discovery of the rôle played by d'Aché in the conspiracy.
Manginot then received an order to proceed to Calvados immediately. On the 23d June he arrived at Caffarelli's bearing this letter of introduction: "The skill, the zeal and good fortune of this officer in these cases, is well known; they were proved in a similar affair, and I ask you to welcome him as he deserves to be welcomed." The préfet was quite willing; he knew too well the habits of the Chouans, and their cleverness in disappearing to have any personal illusions as to the final result of the adventure, but he said nothing and on the contrary showed the greatest confidence in the dexterity of a man who stood so well at court.
Manginot began with a fresh search at Donnay; and, as his reputation obliged him to be successful, and as he was not unwilling to astonish the authorities of Calvados by the quickness of his perceptions, he caused Acquet de Férolles to be arrested. It was he who had first warned the gendarmes of the sojourn of the brigands at Donnay, and this seemed exceedingly suspicious; the same day he gave the order to take Hébert. Several people in the village insinuated that Acquet and Hébert were irreconcilable enemies and that Manginot was on the wrong track; but the detective's head was now swelled with importance and he would not draw back. Following his extravagant deductions he decided that the complicity of Gousset, convicted of drinking and playing skittles the whole way, was undoubted, and the poor man was arrested in his village where he had returned to his wife and children to recover from his excitement. At last Manginot, evidently animated by his blunders, took it into his head that Dupont d'Aisy himself might well have kept Pinteville at dinner and excited the peasants in order to secure the retreat of the brigands, and issued a warrant against him to the stupefaction of Caffarelli who thus saw imprisoned all those whose conduct he had praised, and whom he had given as examples of devotion. Thus, in a region where he had only to touch, so to say, to catch a criminal, Captain Manginot was unlucky enough to incarcerate only the innocent, and to complete the irony, these innocent prisoners made such a poor face before the court of enquiry that his suspicions were justified. Acquet was very anxious to denounce his wife, but he would not speak without certainty and the magistrate before whom he appeared at Falaise notes that in the course of interrogations "he contradicted himself; his replies were far from satisfactory, though he arranged them with the greatest care and reflected long before speaking." At the first insinuation he made against Mme. de Combray and her daughter, the judge indignantly silenced him, and sent him well-guarded to Caen where he was put in close custody. As to Hébert, not wishing to compromise the ladies of La Bijude to whom he was completely devoted, he scarcely replied to the questions put to him; all, even to Dupont d'Aisy lent themselves to the suspicions of Manginot. Sixty guns were found at the mayor's house, which seemed an excessive number, even for the great sportsman he prided himself on being, and here again all indications tended to convince Manginot that he was on the right track.
Mme. Acquet, meanwhile feigned the greatest security. Seeing things straying from the right way, she might indeed imagine that she was removed from all danger, and she had besides, other anxieties. The Chevalier had been waiting in Paris since the 7th of June for the money he so urgently needed, and as nothing appeared in spite of his reiterated demands, he decided to come and fetch it himself; he did not dare, however, to appear near Falaise, so arranged a meeting at Laigle with Lefebre, earnestly entreating him to bring him all the money he possibly could. But the Buquets, with whom the 60,000 francs had been left on the 7th June, obstinately refused to give it up in spite of Mme. Acquet's entreaties; they had removed the money from their garden and hidden it in various places which they jealously kept secret. However, through her influence over Joseph, Mme. Acquet succeeded in obtaining 3,300 francs which she gave the lawyer to take to Le Chevalier, but Lefebre, as soon as he got hold of the money, declared that he had been promised 12,000 francs for his assistance, and that he would keep this on account. He went to meet Le Chevalier at Laigle however, and to calm his impatience told him that Dusaussay was going to start for Paris immediately with 60,000 francs which he would give him intact. Mme. Acquet was desperate; prudence forbade her trying to overcome the Buquets' obstinacy, and they, in order to keep the money, asserted that it belonged to the royal exchequer, and they were responsible for it; so the unhappy woman found that she had committed a crime that the obstinacy of these rapacious peasants rendered useless. She was ready to abandon all in order to rejoin Le Chevalier, ready even to expatriate herself with him, when they heard that Mme. de Combray, hearing rumours of what had happened in Lower Normandy, had decided to come to Falaise, to plead the cause of her farmer, Hébert. She had left Tournebut on the 13th July and taken the Caen coach to Evreux.
