The Three Musketeers
How we cite our quotes:
She rather feared that her preceding operations in England might have been discovered. Buckingham might have guessed that it was she who had cut off the two studs, and avenge himself for that little treachery; but Buckingham was incapable of going to any excess against a woman, particularly if that woman was supposed to have acted from a feeling of jealousy. (50.2)
Milady understands that Buckingham would never avenge himself upon a woman, especially if that woman was said to be acting due to jealousy.
