“How absurd!” said Cicely, and the honesty of her tone seemed to verify Fessenden’s conviction that whatever guilty knowledge this girl might possess, she herself was innocent of crime.

“If it is an absurd idea, then why not return to Mapleton and answer any queries that may be put to you? You are innocent, therefore you have nothing to fear.”

“I have a great deal to fear.”

The girl spoke gently, even sadly, now. She seemed full of anxiety and sorrow, that yet showed no trace of apprehension for herself.

All at once a light broke upon Fessenden. She was shielding somebody. Nor was it hard to guess who it might be!

“Miss Dupuy,” began Rob again, eagerly this time, “I have succeeded in establishing, practically, Mr. Carleton’s innocence. May I not likewise establish your own?”

“Mr. Carleton’s innocence!” repeated the girl, clasping her hands. “Oh, is that true? Then who did do it?”

“We don’t know yet,” went on Rob, hastening to make the most of the advantage he had gained; “but having assured you that it was not Schuyler Carleton, will you not tell me what it is you have been keeping secret?”

“How do you know Mr. Carleton is innocent? Have you proved it? Has some one else confessed?”

“No, no one has confessed. And, indeed, I may as well own up that no one is quite so sure of Mr. Carleton’s innocence as I am myself. But I am sure of it, and I’m going to prove it. Now, will you not help me to do so?”
