When this was done there could be no more doubt. Three fancy daggers were found, one of which had always hung in the chamber of the duchess. All of them were stained with blood. The duke had changed his clothes, and had tried to wash those he took off in the pail whose bloody water he had thrown away. Subsequently it was conjectured that his purpose had been to stab his wife in her sleep, and then by a strong pull to bring down upon her the heavy canopy. The bolt he had unscrewed permitted him at dead of night quietly to enter her chamber. The police were puzzled as to how they ought to treat the murderer. As he was a peer of France, they could not legally arrest him without authority from the Chamber of peers, or from the king. The royal family was at Dreux. The king was appealed to at once, and immediately gave orders to arrest the duke and to summon the peers for his trial. But meantime the duke, who had been guarded by the police in his own chamber, had contrived to take poison. He took such a quantity of arsenic that his stomach rejected it. He did not die at once, but lingered several days, and was carried to prison at the Luxembourg, where the poison killed him by inches. He died untried, having made no confession. His son, who was very young at the time of his parents' death, married an American lady when he grew to manhood. It was a long courtship, for the young duke's income went largely to keep in repair his famous Château de Vaux, where Fouquet had entertained Louis XIV. with regal magnificence. Finally a purchaser was found for the ancestral seat; and relieved of the obligations it involved, the duke married, and retired to his estates in Corsica. As to Mademoiselle de Luzy, she was tried for complicity in the murder of the duchess, and acquitted. There was no evidence whatever against her. But popular feeling concerning her as the inciting cause of the poor duchess's death was so strong that by the advice of her pastor--the Protestant M. Coquerel--she changed her name and came to America. She brought letters of introduction to a family in Boston, who procured her a situation as governess in Connecticut. There she soon after married a Congregational minister. It seems hard to imagine how such a tragedy could have borne its part among the causes of Louis Philippe's downfall; but those who look into Alison or Lamartine will see it set down as one of the events which greatly assisted in bringing about the revolution of February. Mobs, like women, are often swayed by persons rather than by principles. It was believed by the populace that court favor had prevented the duke from going to prison like any common criminal, and that the same influence had procured him the poison by which he escaped a public execution.
