‘Evil is evil, Stregobor,’ said the witcher seriously as he got up. ‘Lesser, greater, middling, it’s all the same. Proportions are negotiated, boundaries blurred. I’m not a pious hermit, I haven’t done only good in my life. But if I’m to choose between one evil and another, then I prefer not to choose at all. Time for me to go. We’ll see each other tomorrow
