The same casket contained ample evidence of the marchioness's share in these transactions. There were a number of letters from her to St. Croix, and the deed of promise which she had executed in his favour for thirty thousand livres. When the marchioness heard that St. Croix was dead, and that his repositories had been sealed up, she showed the utmost anxiety to get possession of the casket. At ten o'clock at night she came to the house of the commissary who had affixed and taken off the seals, and desired to speak with him. Being told by his clerk that he was asleep, she said she had come to inquire about a casket which belonged to her, and which she wished to get back, and would return next day. When she came back, she was told that the casket could not be given up to her. Thinking it high time, therefore, to take care of herself, she went off during the following night, and took refuge in Liege; leaving, however, a power to an attorney to appear for her and contest the validity of the promise she had given to St. Croix. La Chaussée, too, had the impudence to put in a claim to certain sums of money, which, as he pretended, belonged to him, and which were deposited, in places which he mentioned, in St. Croix's study. This proved that La Chaussée was acquainted with the localities of a place into which it was to be presumed that St. Croix admitted none but his confidants and confederates; and La Chaussée was arrested on suspicion, which was greatly strengthened by the confusion he betrayed when informed of the discoveries made at the removal of the seals.
