It appears that the Duc de Richelieu was not in the conspiracy of
the Duc and Duchesse du Maine, but had a plot of his own, which has
put him in the Bastille. He took it into his head that he was so
considerable a person he could not be refused a certain marriage far
above his just pretensions. When that hope vanished, he began, in his
vexation, to plot. He is an arch-debauchee, and a coward; he believes
in neither God nor His word; in all his life he never has done, and
never will do a worthy thing; he is ambitious and false as the devil.
He is not yet twenty-four years old. I do not think him as handsome as
the Court women do, who are mad about him. He has a pretty figure and
fine hair, an oval face and very brilliant eyes, but everything about
him indicates a rascal; he is graceful and is not without cleverness,
but his insolence is great; he is the worst of spoiled youths. The
first time he was put in the Bastille was for saying he was an actual
lover of the Duchesse de Bourgogne and all her young ladies; which was
a horrible lie.
