Presently he said, "I suppose you know that all this is very wrong."
"Why is it wrong?"
"For one thing, you're aiding an escaped criminal, which is wrong in itself, and doubly wrong in your father's daughter. And for another — and this is much worse — if I were what they think me you'd be in the gravest danger at this minute. You shouldn't do things like that, you know."
"If you were a murderer it wouldn't help you much to commit another one just to keep me from saying I saw you."
"If you've committed one, I suspect you don't easily stop at another. You can only be hanged once. And so you don't think I did it?"
"I'm quite sure you didn't."
"What makes you so sure?"
"You're not capable of it."
"Thank you," he said gratefully.
"I didn't mean it that way."
