"Yes, the portress caught Victoire listening to Daubrecq's conversation with me on the telephone; and the Masher, who was watching the house, saw you go out. I suspected, therefore, that you would follow Daubrecq that evening."

"And the woman who came here, late one afternoon ... "

"Was myself. I felt disheartened and wanted to see you."

"And you intercepted Gilbert's letter?"

"Yes, I recognized his writing on the envelope."

"But your little Jacques was not with you?"

"No, he was outside, in a motor-car, with the Masher, who lifted him up to me through the drawing-room window; and he slipped into your bedroom through the opening in the panel."

"What was in the letter?"

"As ill-luck would have it, reproaches. Gilbert accused you of forsaking him, of taking over the business on your own account. In short, it confirmed me in my distrust; and I ran away."

Lupin shrugged his shoulders with irritation:

"What a shocking waste of time! And what a fatality that we were not able to come to an understanding earlier! You and I have been playing at hide-and-seek, laying absurd traps for each other, while the days were passing, precious days beyond repair."

"You see, you see," she said, shivering, "you too are afraid of the future!"

"No, I am not afraid," cried Lupin. "But I am thinking of all the useful work that we could have done by this time, if we had united our efforts. I am thinldng of all the mistakes and all the acts of imprudence which which we should have been saved, if we had been working together. I am thinking that your attempt to-night to search the clothes which Daubrecq was wearing was as vain as the others and that, at this moment, thanks to our foolish duel, thanks to the din which we raised in his house, Daubrecq is warned and will be more on his guard than ever."

Clarisse Mergy shook her head:

"No, no, I don't think that; the noise will not have roused him, for we postponed the attempt for twenty-four hours so that the portress might put a narcotic in his wine." And she added, slowly, "And then, you see, nothing can make Daubrecq be more on his guard than he is already. His life is nothing but one mass of precautions against danger. He leaves nothing to chance... Besides, has he not all the trumps in his hand?"

Lupin went up to her and asked:

"What do you mean to convey? According to you, is there nothing to hope for on that side? Is there not a single means of attaining our end?"

"Yes," she murmured, "there is one, one only... "

He noticed her pallor before she had time to hide her face between her hands again. And again a feverish shiver shook her frame.

He seemed to understand the reason of her dismay; and, bending toward her, touched by her grief:

"Please," he said, "please answer me openly and frankly. It's for Gilbert's sake, is it not? Though the police, fortunately, have not been able to solve the riddle of his past, though the real name of Vaucheray's accomplice has not Leaked out, there is one man, at least, who knows it: isn't that so? Daubrecq has recognized your son Antoine, through the alias of Gilbert, has he not?"

“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 certificates, 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.”
