As soon as she arrived at the Conciergerie, Licquet, without showing himself, had gone to "study" his prisoner. Like an old, caged lioness, this woman of sixty-seven behaved with surprising energy; she showed no evidence of depression or shame; she did as she liked in the prison, complained of the food, grumbled all day, and raged at the gaolers. There was no reason to hope that she would belie her character, nor to count on an emotion she did not feel to obtain any information from her. The prefect had her brought in a carriage to his house on August 23d, and interrogated her for two days. With the experience and astuteness of an old offender, the Marquise assumed complete frankness; but she only confessed to things she could not deny with success. Licquet asked several questions; she did not reply until she had caused them to be repeated several times, under pretence that she did not understand them. She struggled desperately, arguing, quibbling, fighting foot by foot. If she admitted knowing d'Ache and having frequently offered him hospitality, she positively denied all knowledge of his actual residence. In short, when Savoye-Rollin and Licquet sent her back to the Conciergerie, they felt that they had had the worst of it and gained nothing. Bonnoeil, when his turn came told them nothing but what they already knew, and Placide d'Ache flew into a rage and denied everything. The prefect and his acolyte were feeling somewhat abashed at their failure, when the concierge who had taken Mme. de Combray back to the Palais asked to speak to them. He told them that in the carriage the Marquise had offered him a large sum if he would take some letters to one of the prisoners. Accustomed to these requests he had said neither yes nor no, but had told "the Combray woman" that he would see her at night, when going the rounds, and he had come to get the prefect's orders concerning this correspondence. Licquet urged that the concierge be authorised to receive the letters. He hoped by intercepting them to learn much from the confidences and advice the Marquise would give her fellow-prisoners. The idea was at first very repugnant to Savoye-Rollin, but the Marquise's proposal seemed to establish her guilt so thoroughly, that he did not feel obliged to be delicate and consented, not without throwing on his secretary-general (one of Licquet's titles) the responsibility for the proceeding. Having obtained this concession Licquet took hold of the enquiry, and found it a good field for the employment of his particular talents. No duel was ever more pitiless; never did a detective show more ingenuity and duplicity. From "love of the art," from sheer delight in it, Licquet worked himself up against his prisoners with a passion that would be inexplicable, did not his letters reveal the intense joy the struggle gave him. He felt no hatred towards his victims, but only a ferocious satisfaction in seeing them
