Read the excerpt from Fernley House by Laura E. Richards. Then, answer the question that follows.
"No, miss, no; we see her go with Mrs. Peyton, and we never thought but she was all right."
"She may not be there after all!" said Peggy. "Her room is on the other side, isn't it, Margaret? Come on!"
They ran round to the other side of the house. This was apparently still untouched, though the fiery tongues came darting over the rooftree every now and then, hissing and lapping, and the roof itself was covered with sparks and great patches of burning tinder, fragments of the costly stuffs and tissues that the house-owner had so dearly prized. The windows were closed and silent, but all was bright as day in the red glare of the fire.
"Call, Peggy!" whispered Margaret. "I have no voice."
Even as she spoke, a window in the second story was thrown up, and there stood Grace herself, very pale, but quiet as usual.
"There's a young woman faint here," she said. "Too much smoke. The stairs are gone. Is there a ladder, Peggy? Ah, rope! Much better. Clever child! When I say three—throw!"
