KROGSTAD: Your father died on the 29th of September. But, look here; your father has dated his signature the 2nd of October. It is a discrepancy, isn’t it? (NORA is silent.) Can you explain it to me? (NORA is still silent.) It is a remarkable thing, too, that the words "2nd of October," as well as the year, are not written in your father’s handwriting but in one that I think I know.
