A new thought, and she darted to the window, tore down the red worsted blind-cord, and ran back to the door. Down upon her knees with the stiff cord doubled, and a great loop thrust gently under to try and draw the key towards her.

Now it caught, drew it a little way, let it slip, and came through alone; now it thrust it back when the cord was again pushed through. Another trial, and the cord caught, the key grating over the oilcloth, but only to be checked once more by the double fold and lost.

Disappointment upon disappointment, and a great dread upon her mind that her gaoler would return, find out her attempt to escape, and defeat it by bearing away the key.

Another trial, and another, and another, and once more the key caught against that double in the oilcloth; but now a vigorous snatch and it had fallen over it and close to the door, and though the cord came through without, she could now plainly see the wards of the key—touch them with one of the splints—draw them towards her—touch them with a finger—hold the key in her hand—and be at liberty once more.

Her heart beat with excitement, and then seemed to come to a dead stop, for as she stood where she had leaped to her feet, there came once again the sound of footsteps, now descending, and the steps were stayed by the door, where it was evident that some one was listening.

Beat—beat—beat—beat—again her heart throbbed wildly for a few moments. Then again, heavy pulsations that seemed as if they would make her head split with each agonising pang. Then once more her heart seemed to stop.

Would whoever was listening there see that the key was gone, and ask for it? Would she be compelled to give it up, or would they keep watch at the door to see that she did not escape?

“Do you want anything?” said the voice of Mrs Walls.

“No—no!” was the answer, and the last speaker’s heart beat more wildly in dread lest her eagerness should excite suspicion.

No! there was no notice taken: the steps went on along the passage, and seemed to descend to an underground kitchen, while for some minutes the prisoner stood motionless as a statue.
