“Very well. Then go.”

Margie bounded across the room and caught the doorknob wildly.

“Why don’t you open the door?” coolly asked Nora.

“Heavens, I cannot!”

“That’s the easiest way to find out. No, you can’t get out till I say so.”

Margie looked at the woman and then once more at the window between her and the street.

“I’ll call for help,” she exclaimed.

“All right, miss.”

In a moment the poor girl was at the window, but when she drew back the curtain she saw inner shutters of iron.

Truly she was in durance.
