It is to be regretted that we have no details of this expedition. In what costume did Licquet appear at Caen? What personality did he assume? How did he carry out his manoeuvres between Mme. Acquet's friends, his confederate Delaitre and the Prefect Caffarelli, without arousing any one's suspicion or wounding their susceptibilities? It is impossible to disentangle this affair; he was an adept at troubling water that he might safely fish in it, and seemed jealous to such a degree of the means he employed, that he would not divulge the secret to any one. With an instinctive love of mystification, he kept up during his journey an official correspondence with his prefect and a private one with Real. He told one what he would not confess to the other; he wrote to Savoye-Rollin that he was in a hurry to return to Rouen, while by the same post he asked Real to get him recalled to Paris during the next twenty-four hours. "If you adopt this idea, Monsieur, you must be kind enough to select a pretext which will not wound or even scratch any one's amour-propre." The "any one" mentioned here is Savoye-Rollin. What secret had Licquet discovered, that he did not dare to confide, except orally, and then only to the Imperial Chief of Police? We believe that we are not wrong in premising that scarcely had he arrived at Caen when he laid hands on a witness so important, and at the same time so difficult to manipulate, that he was himself frightened at this unexpected _coup de theatre_. Whilst ferreting about in the prisons to which he had obtained access that he might talk to Lanoe and the Buquets, he met Acquet de Ferolles, who had been forgotten there for three months. Whether Mme. de Placene was, as Vannier suspected, employed by the police and knew Licquet's real personality, or whether the latter found another intermediary, it is certain that he obtained Acquet de Ferolles' confidence from the beginning, and that he got the credit of having him set at liberty. It was after this interview that Licquet asked Real to recall him to Paris for twenty-four hours. His journey took place in the early days of November, and on the 12th, on an order from Real Acquet was rearrested and taken in a post-chaise from Donnay to Paris, escorted by a sergeant of police. On the 16th he was entered in the Temple gaol-book, and Real, who hastened to interrogate him, showed him great consideration, and promised that his detention should not be long. A note, which is still to be found among the papers connected with this affair, seems to indicate that this incarceration was not of a nature to cause great alarm to the Lord of Donnay: "M. Acquet has been taken to Paris that he may not interfere with the proceedings against his wife.... It is known that he is unacquainted with his wife's offence, but M. Real believes it necessary to keep him at a distance." That was not the tone in which the police of that period usually spoke of their ordinary prisoners, and it
