Sue—Yes, do come. [Goes with him to the door.] Can you see your way?
Sue—Good night. [She closes the door and comes back to Nat. The Doctor’s footsteps die out.]
Nat—[Savagely.] That damned old fool! What is he doing, sneaking around here all the time? I’ve grown to hate the sight of him.
Sue—Nat! You can’t mean that. Think of how kind he’s been.
Nat—Yes—kindness with a purpose.
Sue—Don’t be silly. What purpose could he have except wanting to help us?
Nat—To find out things, of course, you simpleton. To pump Pa when he’s not responsible for what he’s saying.
Sue—[Indignantly.] Nat!
Nat—Much good it’s done him! I know Pa. Sane or not, he won’t tell that to anyone—not even you or me, Sue. [With sudden fury.] I’m going away—but before I go I’m going to make him tell me! He won’t refuse this time when he knows I’m leaving for good. He’ll be glad then. He’s been so afraid I’d find out, so scared to speak to me even—locking himself up here. But I’ll make him tell—yes, I will!
