Yes, my dear friend, I am perfectly clear upon that point. HELMER. Well? RANK. At the next masquerade I shall be invisible. HELMER. What a comical idea! RANK. There’s a big black hat—haven’t you heard of the invisible hat? It comes down all over you, and then no one can see you. HELMER. [_With a suppressed smile._] No, you’re right there. RANK. But I’m quite forgetting what I came for. Helmer, give me a cigar—one of the dark Havanas. HELMER. With the greatest pleasure. [_Hands cigar-case._ RANK. [_Takes one and cuts the end off._] Thank you. NORA. [_Striking a wax match._] Let me give you a light. RANK. A thousand thanks. [_She holds the match. He lights his cigar at it._ RANK. And now, good-bye! HELMER. Good-bye, good-bye, my dear fellow. NORA. Sleep well, Doctor Rank. RANK. Thanks for the wish. NORA. Wish me the same. RANK. You? Very well, since you ask me—Sleep well. And thanks for the light. [_He nods to them both and goes out._ HELMER. [_In an undertone._] He’s been drinking a good deal. NORA. [_Absently._] I daresay. [HELMER _takes his bunch of keys from his pocket and goes into the hall._] Torvald, what are you doing there? HELMER. I must empty the letter-box; it’s quite full; there will be no room for the newspapers to-morrow morning. NORA. Are you going to work to-night? HELMER. You know very well I am not.—Why, how is this? Some one has been at the lock. NORA. The lock——? HELMER. I’m sure of it. What does it mean? I can’t think that the servants——? Here’s a broken hair-pin. Nora, it’s one of yours. NORA. [_Quickly._] It must have been the children—— HELMER. Then you must break them of such tricks.—There! At last I’ve got it open. [_Takes contents out and calls into the kitchen._] Ellen!—Ellen, just put the hall door lamp out. [_He returns with letters in his hand, and shuts the inner door._ HELMER. Just see how they’ve accumulated. [_Turning them over._] Why, what’s this? NORA. [_At the window._] The letter! Oh no, no, Torvald!
