Quote context

[...]

- Yes, but when you awaken in the morning, what do you remember of the night before? Of your visits to the Englishwoman?

- Sometimes at night, I tend her. I help her when she feels ill. I loosen the nightgown at her throat.

- At her throat. That you remember.

- Can you remember dreams? Can a Vorvolaka in her human form remember the evil that she did at night?

- How can you be so sure?

- This much we know: You walk at night. You arise in the morning refreshed and filled with life, and your friend, every day she goes paler, listless, weaker.

- It is best that you stay away from the others.

- I hope that I'm wrong. I hope that everything that Kyra said is untrue, but until I know, I must watch you.

- Were you ill before?

- Before? Before I came to work for you?

- Yes, I was ill for a long time before.

- But since I came, you've been worse?

- Yes, that was to be expected.

- Why do you ask? You're not thinking that you're at fault? It isn't that, is it?
