King Louis XIV. had been failing for some time, though every one pretended not to notice it; and the Duchess of Maine, ever anxious for the greatness of her family, was very eager to know his testamentary intentions.  Enough was ascertained, by the help of Madame de Maintenon, to show that the King’s dispositions were in favour of the Duke of Orleans, and the mistake was made of confiding to the Duke his future advantage.  As the illness progressed, a council of regency was formed with the Duke of Orleans at its head, and when the King died the Duke was appointed Regent by Parliament, and the Duke of Maine was entrusted with the education of the young King.

The Duchess of Maine, who had come up to Paris for this anxious time, suffered a good deal from insomnia, and now called me in to read to her every night.  But there was more conversation than reading, and she poured out to me in entire confidence all her secrets, projects, complaints and regrets.  This touching confidence made me very deeply attached to her; and when she and her husband removed to the Tuilleries to superintend the King’s education, they took me with them.

In defence of the interests of her family in the succession to the Crown, which were threatened by the Duke of Orleans, Cardinal Polignac and others undertook the preparation of a very learned memoir, based on a great mass of historical and legal precedents; the Duchess threw herself into the most laborious researches to assist them, and I was set to study ancient volumes and to correspond with all kinds of authorities.  The great work was finished at last; it was a fine, well-written production; but it did not repay the trouble it had cost.  The question was decided against the family of Maine, the edict conferring on them the succession to the Crown was revoked, and the rank of princes of the blood was taken from them.

It is impossible to describe the sorrow of my mistress at this sudden overthrow of the fortunes of her family.  She was wholly unable to acquiesce in it, and her illtreatment in France suggested to her the idea of seeking help from the King of Spain.  The Baron de Walef, who was going to that court, undertook to represent her case there, and the Duchess of Maine held secret interviews with the Spanish ambassador in Paris.  Several other persons became implicated in these intrigues; the Duchess became more deeply compromised than she had at first intended; and her interests became interwoven with other chimerical projects, including the restoration of the Pretender in England.  These movements became known to the Duke of Orleans, and my mistress’s intrigues were soon brought to an end.

On December 9, 1718, we were informed that the house of the Spanish Ambassador was surrounded by troops, and a day or two later we learned that our arrest, on the charge of inciting to revolution, might be expected at any moment.  On the 29th, we were awakened early in the morning to find the house full of soldiers; the Duchess was carried off to imprisonment at Dijon, and the Duke of Maine was immured in the citadel of Dourlans in Picardy.
