“Do you go out much in society?”

“Arthur does. Mary and I stay at home. We neither of us care for it.”

“That is unusual in a young girl.”

“She is of a quiet nature. Besides, she is not so very young. She is four-and-twenty.”

“This matter, from what you say, seems to have been a shock to her also.”

“Terrible! She is even more affected than I.”

“You have neither of you any doubt as to your son’s guilt?”

“How can we have when I saw him with my own eyes with the coronet in his hands.”

“I hardly consider that a conclusive proof. Was the remainder of the coronet at all injured?”

“Yes, it was twisted.”

“Do you not think, then, that he might have been trying to straighten it?”

“God bless you! You are doing what you can for him and for me. But it is too heavy a task. What was he doing there at all? If his purpose were innocent, why did he not say so?”

“Precisely. And if it were guilty, why did he not invent a lie? His silence appears to me to cut both ways. There are several singular points about the case. What did the police think of the noise which awoke you from your sleep?”

“They considered that it might be caused by Arthur’s closing his bedroom door.”

“A likely story! As if a man bent on felony would slam his door so as to wake a household. What did they say, then, of the disappearance of these gems?”

“They are still sounding the planking and probing the furniture in the hope of finding them.”

“Have they thought of looking outside the house?”

“Yes, they have shown extraordinary energy. The whole garden has already been minutely examined.”

“Now, my dear sir,” said Holmes. “is it not obvious to you now that this matter really strikes very much deeper than either you or the police were at first inclined to think? It appeared to you to be a simple case; to me it seems exceedingly complex. Consider what is involved by your theory. You suppose that your son came down from his bed, went, at great risk, to your dressing-room, opened your bureau, took out your coronet, broke off by main force a small portion of it, went off to some other place, concealed three gems out of the thirty-nine with such skill that nobody can find them, and then returned with the other thirty-six into the room in which he exposed himself to the greatest danger of being discovered. I ask you now, is such a theory tenable?”

“But what other is there?” cried the banker with a gesture of despair. “If his motives were innocent, why does he not explain them?”

“It is our task to find that out,” replied Holmes; “so now, if you please, Mr. Holder, we will set off for Streatham together, and devote an hour to glancing a little more closely into details.”

My friend insisted upon my accompanying them in their expedition, which I was eager enough to do, for my curiosity and sympathy were deeply stirred by the story to which we had listened. I confess that the guilt of the banker’s son appeared to me to be as obvious as it did to his unhappy father, but still I had such faith in Holmes’s judgement that I felt that there must be some grounds for hope as long as he was dissatisfied with the accepted explanation. He hardly spoke a word the whole way out to the southern suburb, but sat with his chin upon his breast and his hat drawn over his eyes, sunk in the deepest thought. Our client appeared to have taken fresh heart at the little glimpse of hope which had been presented to him, and he even broke into a desultory chat with me over his business affairs. A short railway journey and a shorter walk brought us to Fairbank, the modest residence of the great financier.

Fairbank was a good-sized square house of white stone, standing back a little from the road. A double carriage-sweep[99], with a snow-clad lawn, stretched down in front to two large iron gates which closed the entrance. On the right side was a small wooden thicket, which led into a narrow path between two neat hedges stretching from the road to the kitchen door, and forming the tradesmen’s entrance. On the left ran a lane which led to the stables, and was not itself within the grounds at all, being a public, though little used, thoroughfare. Holmes left us standing at the door and walked slowly all round the house, across the front, down the tradesmen’s path, and so round by the garden behind into the stable lane. So long was he that Mr. Holder and I went into the dining-room and waited by the fire until he should return. We were sitting there in silence when the door opened and a young lady came in. She was rather above the middle height, slim, with dark hair and eyes, which seemed the darker against the absolute pallor of her skin. I do not think that I have ever seen such deadly paleness in a woman’s face. Her lips, too, were bloodless, but her eyes were flushed with crying. As she swept silently into the room she impressed me with a greater sense of grief than the banker had done in the morning, and it was the more striking in her as she was evidently a woman of strong character, with immense capacity for self-restraint. Disregarding my presence, she went straight to her uncle and passed her hand over his head with a sweet womanly caress.

“You have given orders that Arthur should be liberated, have you not, dad?” she asked.

“No, no, my girl, the matter must be probed to the bottom.”

“But I am so sure that he is innocent. You know what woman’s instincts are. I know that he has done no harm and that you will be sorry for having acted so harshly.”

“Why is he silent, then, if he is innocent?”

“Who knows? Perhaps because he was so angry that you should suspect him.”

“How could I help suspecting him, when I actually saw him with the coronet in his hand?”

“Oh, but he had only picked it up to look at it. Oh, do, do take my word for it that he is innocent. Let the matter drop and say no more. It is so dreadful to think of our dear Arthur in prison!”

“I shall never let it drop until the gems are found – never, Mary! Your affection for Arthur blinds you as to the awful consequences to me. Far from hushing the thing up, I have brought a gentleman down from London to inquire more deeply into it.”

“This gentleman?” she asked, facing round to me.

“No, his friend. He wished us to leave him alone. He is round in the stable lane now.”

“The stable lane?” She raised her dark eyebrows. “What can he hope to find there? Ah! this, I suppose, is he. I trust, sir, that you will succeed in proving, what I feel sure is the truth, that my cousin Arthur is innocent of this crime.”

“I fully share your opinion, and I trust, with you, that we may prove it,” returned Holmes, going back to the mat to knock the snow from his shoes. “I believe I have the honour of addressing Miss Mary Holder. Might I ask you a question or two?”

“Pray do, sir, if it may help to clear this horrible affair up.”

“You heard nothing yourself last night?”

“Nothing, until my uncle here began to speak loudly. I heard that, and I came down.”

“You shut up the windows and doors the night before. Did you fasten all the windows?”

“Yes.”

“Were they all fastened this morning?”

“Yes.”

“You have a maid who has a sweetheart? I think that you remarked to your uncle last night that she had been out to see him?”

“Yes, and she was the girl who waited in the drawing-room. and who may have heard uncle’s remarks about the coronet.”

“I see. You infer that she may have gone out to tell her sweetheart, and that the two may have planned the robbery.”

“But what is the good of all these vague theories,” cried the banker impatiently, “when I have told you that I saw Arthur with the coronet in his hands?”

“Wait a little, Mr. Holder. We must come back to that. About this girl, Miss Holder. You saw her return by the kitchen door, I presume?”
