Read the excerpt from act 3 of A Doll’s House. Krogstad [with a searching look at her] : Is that what it all means?—that you want to save your friend at any cost? Tell me frankly. Is that it? Mrs. Linde: Nils, a woman who has once sold herself for another's sake, doesn't do it a second time. Krogstad: I will ask for my letter back. Mrs. Linde: No, no. Krogstad: Yes, of course I will. I will wait here until Helmer comes; I will tell him he must give me my letter back—that it only concerns my dismissal—that he is not to read it— Mrs. Linde: No, Nils, you must not recall your letter. Krogstad: But, tell me, wasn't it for that very purpose that you asked me to meet you here? Mrs. Linde: In my first moment of fright, it was. But twenty-four hours have elapsed since then, and in that time I have witnessed incredible things in this house. Helmer must know all about it. This unhappy secret must be disclosed; they must have a complete understanding between them, which is impossible with all this concealment and falsehood going on. Krogstad: Very well, if you will take the responsibility. But there is one thing I can do in any case, and I shall do it at once. Which evidence from the text best supports the theme that it is better if the truth comes out?
