cat's claws; as I spoke he said in a quick, sharp way:

"Eh!" I could hear the quick intake of his breath. Whilst I was stroking the now quiescent cat, the Doctor went to the table and tore off a piece of blotting-paper from the writing-pad and came back. He laid the paper on his palm and, with a simple "pardon me!" to Miss Trelawny, placed the cat's paw on it and pressed it down with his other hand. The haughty cat seemed to resent somewhat the familiarity, and tried to draw its foot away. This was plainly what the Doctor wanted, for in the act the cat opened the sheaths of its claws and and made several reefs in the soft paper. Then Miss Trelawny took her pet away. She returned in a couple of minutes; as she came in she said:

"It is most odd about that mummy! When Silvio came into the room first—indeed I took him in as a kitten to show to Father—he went on just the same way. He jumped up on the table, and tried to scratch and bite the mummy. That was what made Father so angry, and brought the decree of banishment on poor Silvio. Only his parole, given through me, kept him in the house."

Whilst she had been gone, Doctor Winchester had taken the bandage from her father's wrist. The wound was now quite clear, as the separate cuts showed out in fierce red lines. The Doctor folded the blotting-paper across the line of punctures made by the cat's claws, and held it down close to the wound. As he did so, he looked up triumphantly and beckoned us over to him.

The cuts in the paper corresponded with the wounds in the wrist! No explanation was needed, as he said:

"It would have been better if master Silvio had not broken his parole!"

We were all silent for a little while. Suddenly Miss Trelawny said:

"But Silvio was not in here last night!"

"Are you sure? Could you prove that if necessary?" She hesitated before replying:

"I am certain of it; but I fear it would be difficult to prove. Silvio sleeps in a basket in my room. I certainly put him to bed last night; I remember distinctly laying his little blanket over him, and tucking him in. This morning I took him out of the basket myself. I certainly never noticed him in here; though, of course, that would not mean much, for I was too concerned about poor father, and too much occupied with him, to notice even Silvio."

The Doctor shook his head as he said with a certain sadness:

"Well, at any rate it is no use trying to prove anything now. Any cat in the world would have cleaned blood-marks—did any exist—from his paws in a hundredth part of the time that has elapsed."

Again we were all silent; and again the silence was broken by Miss Trelawny:

"But now that I think of it, it could not have been poor Silvio that injured Father. My door was shut when I first heard the sound; and Father's was shut when I listened at it. When I went in, the injury had been done; so that it must have been before Silvio could possibly have got in." This reasoning commended itself, especially to me as a barrister, for it was proof to satisfy a jury. It gave me a distinct pleasure to have Silvio acquitted of the crime—possibly because he was Miss Trelawny's cat and was loved by her. Happy cat! Silvio's mistress was manifestly pleased as I said:

"Verdict, 'not guilty!'" Doctor Winchester after a pause observed:

"My apologies to master Silvio on this occasion; but I am still puzzled to know why he is so keen against that mummy. Is he the same toward the other mummies in the house? There are, I suppose, a lot of them. I saw three in the hall as I came in."

"There are lots of them," she answered. "I sometimes don't know whether I am in a private house or the British Museum. But Silvio never concerns himself about any of them except that particular one. I suppose it must be because it is of an animal, not a man or a woman."

"Perhaps it is of a cat!" said the Doctor as he started up and went across the room to look at the mummy more closely. "Yes," he went on, "it is the mummy of a cat; and a very fine one, too. If it hadn't been a special favourite of some very special person it would never have received so much honour. See! A painted case and obsidian eyes—just like a human mummy. It is an extraordinary thing, that knowledge of kind to kind. Here is a dead cat—that is all; it is perhaps four or five thousand years old—and another cat of another breed, in what is practically another world, is ready to fly at it, just as it would if it were not dead. I should like to experiment a bit about that cat if you don't mind, Miss Trelawny." She hesitated before replying:

"Of course, do anything you may think necessary or wise; but I hope it will not be anything to hurt or worry my poor Silvio." The Doctor smiled as he answered:

"Oh, Silvio would be all right: it is the other one that my sympathies would be reserved for."

"How do you mean?"

"Master Silvio will do the attacking; the other one will do the suffering."

"Suffering?" There was a note of pain in her voice. The Doctor smiled more broadly:

"Oh, please make your mind easy as to that. The other won't suffer as we understand it; except perhaps in his structure and outfit."

"What on earth do you mean?"

"Simply this, my dear young lady, that the antagonist will be a mummy cat like this one. There are, I take it, plenty of them to be had in Museum Street. I shall get one and place it here instead of that one—you won't think that a temporary exchange will violate your Father's instructions, I hope. We shall then find out, to begin with, whether Silvio objects to all mummy cats, or only to this one in particular."

"I don't know," she said doubtfully. "Father's instructions seem very uncompromising." Then after a pause she went on: "But of course under the circumstances anything that is to be ultimately for his good must be done. I suppose there can't be anything very particular about the mummy of a cat."

Doctor Winchester said nothing. He sat rigid, with so grave a look on his face that his extra gravity passed on to me; and in its enlightening perturbation I began to realise more than I had yet done the strangeness of the case in which I was now so deeply concerned. When once this thought had begun there was no end to it. Indeed it grew, and blossomed, and reproduced itself in a thousand different ways. The room and all in it gave grounds for strange thoughts. There were so many ancient relics that unconsciously one was taken back to strange lands and strange times. There were so many mummies or mummy objects, round which there seemed to cling for ever the penetrating odours of bitumen, and spices and gums—"Nard and Circassia's balmy smells"—that one was unable to forget the past. Of course, there was but little light in the room, and that carefully shaded; so that there was no glare anywhere. None of that direct light which can manifest itself as a power or an entity, and so make for companionship. The room was a large one, and lofty in proportion to its size. In its vastness was place for a multitude of things not often found in a bedchamber. In far corners of the room were shadows of uncanny shape. More than once as I thought, the multitudinous presence of the dead and the past took such hold on me that I caught myself looking round fearfully as though some strange personality or influence was present. Even the manifest presence of Doctor Winchester and Miss Trelawny could not altogether comfort or satisfy me at such moments. It was with a distinct sense of relief that I saw a new personality in the room in the shape of Nurse Kennedy. There was no doubt that that business-like, self-reliant, capable young woman added an element of security to such wild imaginings as my own. She had a quality of common sense that seemed to pervade everything around her, as though it were some kind of emanation. Up to that moment I had been building fancies around the sick man; so that finally all about him, including myself, had become involved in them, or enmeshed, or saturated, or... But now
