Miss Pengarvon stood stock still for a moment or two and shuddered. Then, hesitating no longer, she strode swiftly forward until she reached the Green Parlor. The door was wide open; she had shut and locked it carefully, as she always did, before retiring for the night. She gazed around with anxious eyes, and for the first moment or two, so faint was the light shed by her candle, it seemed to her that the room was empty, but a second glance revealed to her her sister's figure, clad in a dark-grey dressing-gown, crouching on the floor against the old carved bureau that stood in one corner of the room, with her fevered face pressed to its cold, polished panels. Miss Pengarvon put down her candlestick, walked across the floor, and laid a hand gently on her sister's shoulder. "Letitia, what are you doing here?" she asked. Miss Letitia rose to her feet with a sigh, and pushed back her long locks, streaked with grey, which had fallen over her forehead. "Where is Isabel? I followed her here, and now I can't find her," she said, gazing questioningly at her sister, with eyes that were full of an eager, burning light--the light of fever. "This is nonsense, Letitia. You have been dreaming. Come back to your room at once," answered Miss Pengarvon, coldly. "Dreaming, Barbara! Oh, no, it was far too vivid for a dream. I had been fast asleep for I don't know how long, when suddenly I was awakened by hearing my name pronounced quite close to me, as if the speaker were bending over my bed. A second time my name was spoken, and then I knew that it was Isabel who was calling me. I sat up and gazed around, but no one was visible. Then Isabel called me again, and this time the voice seemed to come from outside the door. I got out of bed, put on my dressing-gown, and went out into the corridor. Still, no one was there. Then the voice spoke again, simply calling my name, nothing more; but this time it sounded further away--away down the corridor, and near the head of the stairs. While I was looking and listening, I seemed to see a white figure, very faint and vaguely defined, standing in the dim starlight, near the staircase window, and beckoning to me to follow it. I followed without hesitation, for I had no fear; and yet that seems very strange. As I advanced the figure vanished, and then, when I reached the head of the stairs, I heard my name spoken again, as if from below. Then I descended the stairs and followed the voice till it led me here--here, Barbara! Do you not understand?" Miss Pengarvon's sallow cheeks grew still more sallow. She understood only too well. But before she could say a word, Miss Letitia went on in a strangely eager way: "But now that I am here she does not speak. I have called her, but she will not answer; and yet she must be in trouble, for it was enough to make one weep to hear the way she spoke my name. It is strange--very strange! She has brought me all the way here, and now she hides herself from me."
