"I got warm after I had the tea, and soon fell fast asleep," said Maria, in a voice hushed and trembling. "I knew nothing more until I awoke, suddenly and completely, with the strange feeling, which most people have experienced at one time or another, that some one was bending over me. My eyes opened widely, as though of their own accord; and there, bending down and gazing earnestly into my face, was the face of Katherine Keen."

"Maria!"

"I recognised it in a moment. The room was bright with firelight, and I could not be mistaken. There was the fair hair, with the soft appealing eyes and the sad and serious look in them that I remember so well."

"Did you speak?"

"For a moment or two we gazed at each other; then I think my lips formed her name, but whether any sound came from them I cannot tell. The next thing I knew was that she was no longer there. I started up and saw a black-robed figure vanish through the open doorway and the door close noiselessly behind it. For an instant I thought I should have died."

"Black-robed," repeated Ella mechanically, remembering that this apparition had been always so described.

"She was in black from head to foot. Something black covered her head, which she held with the fingers of one hand under the chin. With her disappearance I sprang to the door, opened it, and rushed into the corridor."

"After her! You had courage, Maria."

"I had no courage. I was too terrified to remain alone, and was hastening to you. She was not to be seen; she had disappeared. A lamp was burning at the farther end of the passage, but the passage was quite empty, quite still; not a sound in it, save the beating of my own heart. Oh Ella! I have heard the mysteries of Heron Dyke spoken of, but I never thought to witness anything myself."

"Yes, Heron Dyke has no doubt its unhappy mysteries; has had them for some time now," sighed Ella, catching up her breath with a sob. "And I know not how to solve them."
