The stranger returned my stare with perfect composure, and in a second or two during which we regarded each other I had time to observe his appearance. He was well dressed, all in black, with a modern, black broadcloth frockcoat buttoned close. He was very tall and strongly built, his face was sallow and heavy featured, and he wore a short, black beard. I bowed and addressed him: "I'm sorry! I didn't know any one was waiting. Do you wish to see me or my husband?" I said politely. The man made no reply, but at once began to glide, not walk, towards a closed glass door leading to a conservatory on the left. His eyes never left mine. Without opening the door he passed through it and vanished. Then I realized and darted after him, throwing open the door and staring beyond. Nothing! Nothing physical could have passed through a glass door without shattering it, and that is all there is to this story. The man had no connection with us nor, so far as we could learn, with the former occupants of the house. A very old friend of mine, Mrs. Sinclair, wife of the late Sir Tollemache Sinclair's second son, told me of an experience she and her mother once had when visiting a cousin, Major Fetherston Dilke, of Maxstoke Castle, Warwickshire. The Castle is ancient and surrounded by a moat, and within the moat lies a tennis court. In order to reach their rooms on the ground floor, Mrs. Sinclair and her mother had to pass through a great stone hall filled with fine old oak and armor. Beyond that their way lay through the remains of an old chapel, which once had been extensively damaged by fire. One evening after playing tennis till rather late, Mrs. Sinclair and her mother hastened indoors to change for dinner. As they passed through the chapel Mrs. Sinclair saw her mother suddenly shrink back against the wall; at the same time she exclaimed, "Oh, May, stand aside and let that person pass." Mrs. Sinclair looked round, but could see no one. Again her mother cried out insistently: "Oh, do let her pass." "But no one is here," Mrs. Sinclair assured her. Then seeing that her mother looked terrified she took her by the arm and hurried her to their rooms. When the door was shut Mrs. Sinclair tried to soothe her mother's agitation, and asked her what she had seen, and why she was so disturbed. Her mother replied: "There was a young woman in the corner who was trying hard to escape observation, and the sight of her gave me the most uncomfortable feeling. She was not a maidservant, and wore no cap. She was dressed in a mauve print gown with a violet sprig upon it. She might have been a needle-woman." Mrs. Sinclair calmed her mother as well as she could, and they went down to dinner together. During the meal what was her horror to hear her mother say to their host, "Oh, William, I feel sure there are ghosts in the Castle. I've seen one to-night." There was a most uncomfortable silence after this, and Major Fetherston Dilke looked terribly agitated.
