“That which my son himself indicated⁠—that of the cupboard of the lumber-room.”

“Have you it here?”

“That is it on the dressing-table.”

Sherlock Holmes took it up and opened the bureau.

“It is a noiseless lock,” said he. “It is no wonder that it did not wake you. This case, I presume, contains the coronet. We must have a look at it.” He opened the case, and taking out the diadem he laid it upon the table. It was a magnificent specimen of the jeweller’s art, and the thirty-six stones were the finest that I have ever seen. At one side of the coronet was a cracked edge, where a corner holding three gems had been torn away.

“Now, Mr. Holder,” said Holmes, “here is the corner which corresponds to that which has been so unfortunately lost. Might I beg that you will break it off.”
