I remember reading a page of a book by Marc Olden while in a
bookstore. It was a guy, I think a criminal, thinking to himself that
he had to ask this woman to agree to do something illegal for him. He
thought that she, at first, wouldn’t do it, but bragged to himself
that after he took her to bed she would definitely go through with it.
 
It went along the lines of "Once she's clawing the sheets, then I know
she'll tell/do whatever I ask."

I’ve read the books Dai-Sho, Gai-Jin, and Krait by Olden, so it wasn’t
any of those.

This question has been asked before (ID 43603).

Which Marc Olden book does this thought monologue comes from, and in
which chapter is it?
