"Interest you?" he said, in some exasperation. He had expected her to fly into a passion. "Don't you take me seriously, madam?"

"As far as you have gone, yes."

Mr. Wrandall could hold in no longer. He was most uncomfortable.

"See here, Smith, out with it. Let us have your story. My daughter-in-law is not in the least alarmed. You've been on the wrong track, of course. But that isn't the point. What we want now is to find out just where we stand."

"You put it in a rather compromising way, Mr. Wrandall. The pronoun 'we' is somewhat general, if you will permit me to say so. Do you expect me to discuss my findings in the presence of Mrs. Wrandall and her counsel?"

"Certainly, sir, certainly. You need have no hesitancy on that score. I dare say you came here knowing that what you were to say would go no further than these four walls."

"Would you say that, sir, if I were to submit proof that would make it look so black for Mrs. Wrandall that you couldn't very well doubt her complicity in the crime, even though you saw fit to let it go no further than these four walls?"

Mr. Wrandall hesitated. A heavy frown appeared between his eyes; his fingers worked nervously on the arm of the chair.

"I may say to you, Mr. Smith, that if you produce conclusive proof I shall do my duty as a law-respecting citizen. I would not hesitate on that score."

Sara looked at him through half-closed lids. His jaws were firmly set.
