less than ten days he was a corpse! His death seemed so much the result of disease, that no suspicions were excited.

When the two brothers arrived from the provinces to render the last sad duties to their sire, they found their sister as grieved, to all outward appearance, as even filial affection could desire: but the young men only came to perish. They stood between Sainte Croix and the already half-clutched go]d, and their doom was sealed. A man, named La Chaussée, was hired by Sainte Croix to aid in administering the poisons; and, in less than six weeks’ time, they had both gone to their long home.

Suspicion was now excited; but so cautiously had all been done, that it found no one upon whom to attach itself. The Marquise had a sister, and she was entitled, by the death of her relatives, to half the property. Less than the whole would not satisfy Sainte Croix, and he determined that she should die the same death as her father and brothers. She was too distrustful, however; and, by quitting Paris, she escaped the destruction that was lurking for her.

The Marquise had undertaken these murders to please her lover. She was now anxious to perpetrate another on her own account. She wished to marry Sainte Croix; but, though separated from her husband, she was not divorced. She thought it would be easier to poison him than to apply to the tribunals for a divorce, which might, perhaps, be refused. But Salute Croix had no longer any love for his guilty instrument. Bad men do not admire others who are as bad as themselves. Though a villain himself, he had no desire to marry one, and was not at all anxious for the death of the Marquis. He seemed, however, to enter into the plot, and supplied her with poison for her husband: but he took care to provide a remedy. La Brinvilliers poisoned him one day, and Sainte Croix gave him an antidote the next. In this manner he was buffetted about between them for some time, and finally escaped with a ruined constitution and a broken heart.

But the day of retribution was at hand, and a terrible mischance brought the murders to light. The nature of the poisons compounded by Salute Croix was so deadly, that, when working in his laboratory, he was obliged to wear a mask, to preserve himself from suffocation. One day, the mask slipped off, and the miserable wretch perished in his crimes. His corpse was found, on the following morning, in the obscure lodging where he had fitted up his laboratory. As he appeared to be without friends or relatives, the police took possession of his effects. Among other things was found a small box, to which was affixed the following singular document:—

“I humbly beg, that those into whose hands this box may fall, will do me the favour to deliver it into the hands only of the Marchioness de Brinvilliers, who resides in the Rue Neuve St. Paul, as everything it contains concerns her, and belongs to her alone; and as, besides, there is nothing in it that can be of use to any person but her. In case she shall be dead before me, it is my wish that it be burned, with everything it contains, without opening or altering anything. In order that no one may plead ignorance, I swear by the God that I adore, and by all that is held most sacred, that I assert nothing but the truth: and if my intentions, just and reasonable as they are, be thwarted in this point by any persons, I charge their consciences with it, both in this world and that which is to come, in order that I may unload mine. I protest that this is my last will. Done at Paris, the 25th of May, 1672.

(Signed) Sainte Croix.”

This earnest solicitation, instead of insuring respect as was intended, excited curiosity. The box was opened, and found to contain some papers, and several vials and powders. The latter were handed to a chemist for analysis, and the documents were retained by the police, and opened. Among them was found a promissory note of the Marchioness de Brinvilliers, for thirty thousand francs, to the order of Sainte Croix. The other papers were of greater importance, as they implicated both her and her servant, La Chaussée, in the recent murders. As soon as she was informed of the death of Sainte Croix, she made an attempt to gain possession of his papers and the box; but, being refused, she saw that there was no time to be lost, and immediately quitted. Next morning the police were on her trail; but she succeeded
