"And will remain so two weeks?"
"If humored."
"You are sure she is implicated in this crime?"
"She was a witness to it."
"And that she speaks the truth when she declares that she is the only person who can point out the criminal?"
"Yes; that is, she is the only one who will do it. The attitude taken by the Van Burnams, especially by Howard just now in the presence of this girl, shows how little we have to expect from them."
"Yet you think they know as much as she does about it?"
"I do not know what to think. For once I am baffled, Superintendent. Every passion which this woman possesses was roused by her unexpected meeting with Howard Van Burnam, and yet their indifference when confronted, as well as her present action, seems to argue a lack of connection between them which overthrows at once the theory of his guilt. Was it the sight of Franklin, then, which really affected her? and was her apparent indifference at meeting him only an evidence of her self-control? It seems an impossible conclusion to draw, and indeed there are nothing but hitches and improbable features in this case. Nothing fits; nothing jibes. I get just so far in it and then I run up against a wall. Either there is a superhuman power of duplicity in the persons who contrived this murder or we are on the wrong tack altogether."
"In other words, you have tried every means known to you to get at the truth of this matter, and failed."
"I have, sir; sorry as I may be to acknowledge it."
