There was a long silence. Then Winter, bending over her, spoke almost in the whisper of those who share a shameful secret.

"You say that Mr. Furneaux was her husband? You know it?"

She trembled violently, but nerved herself to answer:

"Yes, I know it."

"Tell me everything. You must! Do you understand? I order you."

"She told me herself when we were friends. She was married to him in the church of St. Germain l'Auxerrois in Paris on the 7th of November in the year '98. But she soon left him, since he had not the means to support her. I have her marriage certificate in my trunk."

Winter sat some minutes spellbound, his big round eyes staring at the girl, but not seeing her, his forehead glistening. This, then, supplied the long-sought motive. The unfaithful wife was about to marry another. This was the key. An affrighting callousness possessed him. He became the cold, unbending official again.

"You must get up at once, and give me that certificate," he said in the tone of authority, and went out of the room. In a little while she placed the paper in his hands, and he went away with it. Were she not so distraught she might have seen that it shook in his fingers.

Now he, like Clarke, held all the threads of an amazing case.

The next afternoon Furneaux was to arrest Osborne—it was for him, Winter, then, to anticipate such an outrage by the swift arrest of Furneaux. But was he quite ready? He wished he could secure another day's grace to collate and systematize each link of his evidence, and he hurried to Osborne's house in order to give Osborne a hint to vanish again for a day or two. Nevertheless, when at the very door, he paused, refrained, thought that he would manage things differently, and went away.
