During dinner Mrs. Grant remained in the room, and with her Sergeant Daw, who wished to complete a minute examination which he had undertaken of everything in the room and near it. At nine o'clock Miss Trelawny and I went in to relieve the Doctor. She had lain down for a few hours in the afternoon so as to be refreshed for her work at night. She told me that she had determined that for this night at least she would sit up and watch. I did not try to dissuade her, for I knew that her mind was made up. Then and there I made up my mind that I would watch with her—unless, of course, I should see that she really did not wish it. I said nothing of my intentions for the present. We came in on tiptoe, so silently that the Doctor, who was bending over the bed, did not hear us, and seemed a little startled when suddenly looking up he saw our eyes upon him. I felt that the mystery of the whole thing was getting on his nerves, as it had already got on the nerves of some others of us. He was, I fancied, a little annoyed with himself for having been so startled, and at once began to talk in a hurried manner as though to get over our idea of his embarrassment:

"I am really and absolutely at my wits' end to find any fit cause for this stupor. I have made again as accurate an examination as I know how, and I am satisfied that there is no injury to the brain, that is, no external injury. Indeed, all his vital organs seem unimpaired. I have given him, as you know, food several times and it has manifestly done him good. His breathing is strong and regular, and his pulse is slower and stronger than it was this morning. I cannot find evidence of any known drug, and his unconsciousness does not resemble any of the many cases of hypnotic sleep which I saw in the Charcot Hospital in Paris. And as to these wounds"—he laid his finger gently on the bandaged wrist which lay outside the coverlet as he spoke, "I do not know what to make of them. They might have been made by a carding–machine; but that supposition is untenable. It is within the bounds of possibility that they might have been made by a wild animal if it had taken care to sharpen its claws. That too is, I take it, impossible. By the way, have you any strange pets here in the house; anything of an exceptional kind, such as a tiger–cat or anything out of the common?" Miss Trelawny smiled a sad smile which made my heart ache, as she made answer:

"Oh no! Father does not like animals about the house, unless they are dead and mummied." This was said with a touch of bitterness—or jealousy, I could hardly tell which. "Even my poor kitten was only allowed in the house on sufferance; and though he is the dearest and best–conducted cat in the world, he is now on a sort of parole, and is not allowed into this room."

As she was speaking a faint rattling of the door handle was heard. Instantly Miss Trelawny's face brightened. She sprang up and went over to the door, saying as she went:

"There he is! That is my Silvio. He stands on his hind legs and rattles the door handle when he wants to come into a room." She opened the door, speaking to the cat as though he were a baby: "Did him want his movver? Come then; but he must stay with her!" She lifted the cat, and came back with him in her arms. He was certainly a magnificent animal. A chinchilla grey Persian with long silky hair; a really lordly animal with a haughty bearing despite his gentleness; and with great paws which spread out as he placed them on the ground. Whilst she was fondling him, he suddenly gave a wriggle like an eel and slipped out of her arms. He ran across the room and stood opposite a low table on which stood the mummy of an animal, and began to mew and snarl. Miss Trelawny was after him in an instant and lifted him in her arms, kicking and struggling and wriggling to get away; but not biting or scratching, for evidently he loved his beautiful mistress. He ceased to make a noise the moment he was in her arms; in a whisper she admonished him:

"O you naughty Silvio! You have broken your parole that mother gave for you.
