"But surely," and her voice was broken by the shortness of her breathing, "surely you never thought this of me?"

But Bat did not deny it.

"What else was I to do when things piled up as they did? Some of them I don't understand at this minute, and maybe I'll never understand them. But there are others," and he looked at her with frank inquiry in his face, "that you can explain; and, Nora, I'm looking to you to do it."

And with that he told her of the things he had heard from Big Slim and of those he had seen at Bohlmier's hotel. She listened with many little gasps and surprised gestures.

"To think of that man being so near to me that night," she said, when he had done, "and watching me with such an intent. And now, poor Bat," with a little sound in her voice which was part a sob and part a laugh, "because he saw so much and understood so little, and told it all to you, I will have to speak of something I never expected to make known to any one. You know how I have always dreaded and detested divorce; how the thought of it almost sickened me? Well, Bat, two years ago I felt I could endure Tom Burton no longer, and had all the preliminary papers for a proceeding made out."

"What!" said Scanlon. "You, Nora!"

"I did. But then all my old feeling against the thing overtook me, and I laid the papers away in a little silver box which I kept in a drawer in my room. When Tom Burton struck and robbed me that night, I was in a perfect whirl of feeling. I resolved to be free of him forever. And I'd do it at once. What I was seen to take from the drawer, Bat, was the little silver box holding those papers; I rushed from the house meaning to go to my lawyer. And I was a half dozen blocks away when I came out of the state I was in, realized the hour and the impossibility of the whole situation, and returned home."

"That's it," said Bat, with the sigh of a man relieved of a heavy burden. "That's it. I might have known that it would be something of that sort. Then you did not go to Stanwick at all that night?"

"I never dreamed of such a thing. And when I first heard of this man you call Big Slim," went on Nora, "it was in a letter he wrote me after the murder, and of which he spoke guardedly. I felt that this was a clue that if followed I might be able to show poor Frank Burton to be innocent after all. So I did what I otherwise would never have done; I went to the place mentioned, which was the hotel kept by that fiendish old man Bohlmier."

"What did they want?"
