Two or three times she lost her way by turning down the wrong corridor and was obliged to ramble up and down until she found the right one; but at last she reached her own floor again, though she was some distance from her own room and did not know exactly where she was.
"I believe I have taken a wrong turning again," she said, standing still at what seemed the end of a short passage with tapestry on the wall.

"I don't know which way to go.

How still everything is!" It was while she was standing here and just after she had said this that the stillness was broken by a sound.

It was another cry, but not quite like the one she had heard last night; it was only a short one, a fretful, childish whine muffled by passing through walls.
"It's nearer than it was," said Mary, her heart beating rather faster.
"And it _is_ crying." She put her hand accidentally upon the tapestry near her, and then sprang back, feeling quite startled.

The tapestry was the covering of a door which fell open and showed her that there was another part of the corridor behind it, and Mrs.Medlock was coming up it with her bunch of keys in her hand and a very cross look on her face.
"What are you doing here ?" she said, and she took Mary by the arm and pulled her away.
