The Tower of the Swallow (The Witcher, #6)

by Andrzej Sapkowski

When Regis, for the third time, gave her an answer to a question as she was halfway through asking, she cursed him roundly, using words and expressions capable of making even a hoary mercenary blush in embarrassment. Surprisingly enough it worked; the vampire lost his annoying mannerism in the blink of an eye. The conclusion thus being that the most effective defence against intellectual domination is roundly to affront the domineering intellectual.
