"If you take any step with the obvious intention of fixing Dora into some position or forcing her to act in some way, she re-acts contrariwise. ... She has at present, so far as we know, no motive for not making the Decree Absolute. ... If you withhold the costs, you supply such a motive; which she would be all the more ready to act on, because the withholding of the costs would not involve her own detriment. She would be in the happy position of being able to spite your face without cutting off her own nose."
