"You are certainly an admirable witness," said Holmes. "I may need some of these dates which you have noted."
"I learned method among other things from my great teacher. From the time that I observed abnormality in his behaviour I felt that it was my duty to study his case. Thus I have it here that it was on that very day, July 2d, that Roy attacked the professor as he came from his study into the hall. Again, on July 11th, there was a scene of the same sort, and then I have a note of yet another upon July 20th. After that we had to banish Roy to the stables. He was a dear, affectionate animal — but I fear I weary you."
Mr. Bennett spoke in a tone of reproach, for it was very clear that Holmes was not listening. His face was rigid and his eyes gazed abstractedly at the ceiling. With an effort he recovered himself.
"Singular! Most singular!" he murmured. "These details were new to me, Mr. Bennett. I think we have now fairly gone over the old ground, have we not? But you spoke of some fresh developments."
The pleasant, open face of our visitor clouded over, shadowed by some grim remembrance. "What I speak of occurred the night before last," said he. "I was lying awake about two in the morning, when I was aware of a dull muffled sound coming from the passage. I opened my door and peeped out. I should explain that the professor sleeps at the end of the passage—"
"The date being?" asked Holmes.
Our visitor was clearly annoyed at so irrelevant an interruption.
"I have said, sir, that it was the night before last — that is, September 4th."
Holmes nodded and smiled.
"Pray continue," said he.
"He sleeps at the end of the passage and would have to pass my door in order to reach the staircase. It was a really terrifying experience, Mr. Holmes. I think that I am as strong-nerved as my neighbours, but I was shaken by what I saw. The passage was dark save that one window halfway along it threw a patch of light. I could see that something was coming along the passage, something dark and crouching. Then suddenly it emerged into the light, and I saw that it was he. He was crawling, Mr. Holmes — crawling! He was not quite on his hands and knees. I should rather say on his hands and feet, with his face sunk between his hands. Yet he seemed to move with ease. I was so paralyzed by the sight that it was not until he had reached my door that I was able to step forward and ask if I could assist him. His answer was extraordinary. He sprang up, spat out some atrocious word at me, and hurried on past me, and down the staircase. I waited about for an hour, but he did not come back. It must have been daylight before he regained his room."
"Well, Watson, what make you of that?" asked Holmes with the air of the pathologist who presents a rare specimen.
"Lumbago, possibly. I have known a severe attack make a man walk in just such a way, and nothing would be more trying to the temper."
"Good, Watson! You always keep us flat-footed on the ground. But we can hardly accept lumbago, since he was able to stand erect in a moment."
"He was never better in health," said Bennett. "In fact, he is stronger than I have known him for years. But there are the facts, Mr. Holmes. It is not a case in which we can consult the police, and yet we are utterly at our wit's end as to what to do, and we feel in some strange way that we are drifting towards disaster. Edith — Miss Presbury— feels as I do, that we cannot wait passively any longer."
"It is certainly a very curious and suggestive case. What do you think, Watson?"
"Speaking as a medical man," said I, "it appears to be a case for an alienist. The old gentleman's cerebral processes were disturbed by the love affair. He made a journey abroad in the hope of breaking himself of the passion. His letters and the box may be connected with some other private transaction — a loan, perhaps, or share cenificates, which are in the box."
"And the wolfhound no doubt disapproved of the financial bargain. No, no, Watson, there is more in it than this. Now, I can only suggest—"
What Sherlock Holmes was about to suggest will never be known, for at this moment the door opened and a young lady was shown into the room. As she appeared Mr. Bennett sprang up with a cry and ran forward with his hands out to meet those which she had herself outstretched.
"Edith, dear! Nothing the matter, I hope?"
"I felt I must follow you. Oh, Jack, I have been so dreadfully frightened! It is awful to be there alone."
"Mr. Holmes, this is the young lady I spoke of. This is my fiancee."
"We were gradually coming to that conclusion, were we not, Watson?" Holmes answered with a smile. "I take it, Miss Presbury, that there is some fresh development in the case, and that you thought we should know?"
Our new visitor, a bright, handsome girl of a conventional English type, smiled back at Holmes as she seated herself beside Mr. Bennett.
"When I found Mr. Bennett had left his hotel I thought I should probably find him here. Of course, he had told me that he would consult you. But, oh, Mr. Holmes, can you do nothing for my poor father?"
"I have hopes, Miss Presbury, but the case is still obscure. Perhaps what you have to say may throw some fresh light upon it."
"It was last night, Mr. Holmes. He had been very strange all day. I am sure that there are times when he has no recollection of what he does. He lives as in a strange dream. Yesterday was such a day. It was not my father with whom I lived. His outward shell was there, but it was not really he."
"Tell me what happened."
"I was awakened in the night by the dog barking most furiously. Poor Roy, he is chained now near the stable. I may say that I always sleep with my door locked; for, as Jack — as Mr. Bennett — will tell you, we all have a feeling of impending danger. My room is on the second floor. It happened that the blind was up in my window, and there was bright moonlight outside. As I lay with my eyes fixed upon the square of light, listening to the frenzied barkings of the dog, I was amazed to see my father's face looking in at me. Mr. Holmes, I nearly died of surprise and horror. There it was pressed against the windowpane, and one hand seemed to be raised as if to push up the window. If that window had opened, I think I should have gone mad. It was no delusion, Mr. Holmes. Don't deceive yourself by thinking so. I dare say it was twenty seconds or so that I lay paralyzed and watched the face. Then it vanished, but I could not — I could not spring out of bed and look out after it. I lay cold and shivering till morning. At breakfast he was sharp and fierce in manner, and made no allusion to the adventure of the night. Neither did I, but I gave an excuse for coming to town— and here I am."
Holmes looked thoroughly surprised at Miss Presbury's narrative.
"My dear young lady, you say that your room is on the second floor. Is there a long ladder in the garden?"
"No, Mr. Holmes, that is the amazing part of it. There is no possible way of reaching the window — and yet he was there."
"The date being September 5th," said Holmes. "That certainly complicates matters."
It was the young lady's turn to look surprised. "This is the second time that you have alluded to the date, Mr. Holmes," said Bennett. "Is it possible that it has any bearing upon the case?"
"It is possible — very possible — and yet I have not my full material at present."
"Possibly you are thinking of the connection between insanity and phases of the moon?"
"No, I assure you. It was quite a different line of thought. Possibly you can leave your notebook with me, and I will check the dates. Now I think, Watson, that our line of action is perfectly clear. This young lady has informed us — and I have the greatest confidence in her intuition — that her father remembers little or nothing which occurs upon certain dates. We will therefore call upon him as if he had given us an appointment upon such a date. He will put it down to his own lack of memory. Thus we will open our campaign by having a good close view of him."
