"You seem to know more than I imagined," she said. "Perhaps I shall understand better when I know what brings you here. But Carl Sartoris is my brother."

"So he has gone back to his mother's maiden name! Does an honest man want to do anything of that kind? But for the expression of your face, which is sweet and fair as ever, I should say that you were in this business. But I have only to glance at you to feel assured on that point. You say that your brother is more sinned against than sinning. Can you look me in the face and say that he has no past behind him, that he is not making a mystery now?"

The girl's face grew pale and she cast down her eyes. Berrington kept down his rising passion.

"You cannot answer me," he went on. "You find it impossible to do so. You are running great risks for a worthless creature who is as crooked in mind as he is in body."

"Oh, don't," Mary Sartoris said. "Don't say such terrible things, please; they hurt me."

"My dear girl, I am sorry, but it is best to state these things plainly. You may not know everything, but you can guess a great deal. Otherwise, why did you try and see Sir Charles Darryll the night before his death, why did you write him the note that was

found in his bedroom? And again, why did you stay in the hotel that night and try to warn the servants on night duty? You see, Mary, it is quite useless to try to keep the secret from me."

Mary Sartoris looked at the speaker with dilated eyes. For a moment she could not speak. And yet there were no signs of guilty terror on her face.

"I did not imagine that you knew so much," she said.

"I know more, but I would far rather know a great deal more," Berrington admitted. "Mind you, matters are out of my hands and the police are hot on the track. Why do you not confess everything and save yourself, Mary? For instance, you stand a chance of being placed in the dock on a charge of being concerned in the disappearance of Sir Charles Darryll's body."
