Of course, no one dreams to-day of accusing the duke of having knowingly played any part in the fabrication of the anonymous letters; but there is no doubt that, with his utter absence of discretion, his lack of intellectual brilliancy, and the thoroughly royal predilection for gossip and tittle-tattle, which monopolize to this day his interest, he imparted to her, in the course of his daily visits, a vast amount of news and information which she could not possibly have obtained from any one else. Dissipated, foolish and indiscreet to an incredible extent, the duke is nevertheless an honorable man, and in spite of the suspicions entertained at one time concerning him by the Schraders, the Hohenaus, the Anhalts, and the Reischachs, there is no doubt that he had not the slightest conception of the manner in which the gossip which he retailed day by day to his _inamorata_ was used by her for the fabrication of her anonymous letters. It was Baron von Kotze's cousin, Captain Dietrich Kotze, mentioned in the preceding chapter as having espoused the cause of his unfortunate relative with particular vigor, to whom belongs the credit of having discovered the culprit. He accomplished this more through a piece of good fortune than by design, for he was put on the right scent by a mere chance remark which he happened to overhear at a dinner party in Paris. The information which he obtained was imparted to the emperor, and the latter without a moment's hesitation gave orders that his palace police should visit the "Grande Dame's" residence during the following night, take possession of all her papers and correspondence, and convey her to a small town, near the Belgian frontier, where she was to be kept by the police under strict surveillance, without being permitted to see any one, until further orders. It is impossible to say exactly what was discovered among these papers, but it is generally understood that the police recovered possession of the missing diary of Princess Charlotte, and obtained ample proofs of the fact that the fair foreigner was the author of all the anonymous letters. After a twenty-four hours' detention, she was conducted to the frontier by the police, and warned against returning to Germany. If no severer measures were taken against her, it is because it would have resulted in a more or less public disclosure of the indiscreet rôle played by the duke in the matter, and likewise because she really knew too much! In fact, there is scarcely a secret pertaining to the reigning family, or to the Court of Prussia, with which she is not acquainted, and the fact that she should have refrained from making any attempt to publish them to the world, gives rise to the presumption that means of a financial character, or else some threats of terrorism, have been used to insure her silence.
