"Let him go, I say. What harm can he do?"

"We slugged him to get him here. He can report it to the police, and have you arrested, and these two men."

"And what evidence would he have?" she asked. "Who would testify that he was telling the truth? These two men can keep out of sight for the present. He has not seen your face because of your mask. And to charge me with slugging him would be ridiculous."

"This house——"

"Is vacant, so far as the neighbors know; it is owned by a man whose wife died, and who has been gone for more than a year. The agent who rented it to us furnished, is one of us. We can simply close it up and not come here again. If he complained, and the police investigated, they would find the house closed, and the nearest neighbors would declare that it had been closed since the owner went away. The furniture is not even dusted."

"That part is all right."

"And that attack on Prale in the Park during the afternoon!" she went on. "That was a mistake. Suppose Detective Farland managed to connect that with us. I tell you we must not break a law, or Sidney Prale may get the advantage!"

"We can't handle an affair like this with kid gloves!" the masked man declared.

"We do as I say, or I shall go to Sidney Prale and tell him everything and rob you of your vengeance!"

"You would do that!" the masked man cried, springing from his chair.
