sincerity, and that her object was what we now know it to have been, namely, to pledge France324 to a war with Spain, whilst her own hands were free. The “monk” Marchaumont, too, was equally undeceived and sick of the whole affair; blamed by Alen?on for his ill-success, and ceaselessly begging for his recall.

So when La Mothe Fénélon, on his way to Scotland, spoke to her about the relations between France and England, she gave him a piece of her
