"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 Lo 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."

"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?"
"Do you know him?"
"Oh, yes; he is the greengrocer who brings our vegetables round. His name is Francis Prosper."
"He stood," said Holmes, "to the left of the door—that is to say, further up the path than is necessary to reach the door?"
"Yes, he did."
"And he is a man with a wooden leg?"
Something like fear sprang up in the young lady's expressive black eyes. "Why,
