“If one would give me six lines written by the hand of the most honest man, I would find something in them to have him hanged.”
More generally known as Cardinal Richelieu.

but a quick perusal of de Motteville's bio suggests she had been exiled from court at Richelieu's behest, so she may not exactly be a disinterested observer, but was probably very aware of court politics in the years before her arrival.
For what it's worth, I haven't been able to find (Isaac de?) "Laffemas" via full-text search of any of the scans of her memoires I've turned up. (Two of them I searched for "innocent", a word seemingly rare in court memoirs, but no luck there either.) Gallica has a much longer scan (about 50% more pages) but it doesn't seem to have been OCR'ed, and I'm not going to manually check 630pp.
