ceman has recognised it."

She gave a gasp and her head dropped back in the chair.

"Come, Lady Hilda. You have the letter. The matter may still be
adjusted. I have no desire to bring trouble to you. My duty ends when
I have returned the lost letter to your husband. Take my advice and be
frank with me; it is your only chance."

Her courage was admirable. Even now she would not own defeat.

"I tell you again, Mr. Holmes, that you are under some absurd illusion."

Holmes rose from his chair.

"I am sorry for you, Lady Hilda. I have done my best for you; I can see
that it is all in vain."

He rang the bell. The butler entered.

"Is Mr. Trelawney Hope at home?"

"He will be home, sir, at a quarter to one."

Holmes glanced at his watch.

"Still a quarter of an hour," said he. "Very good, I shall wait."

The butler had hardly closed the door behind him when Lady Hilda
was down on her knees at Holmes's feet, her hands out-stretched, her
beautiful face upturned and wet with her tears.

"Oh, spare me, Mr. Holmes! Spare me!" she pleaded, in a frenzy of

"How can we return it?" Holmes muttered. "Quick, quick, we must think of
some way! Where is the despatch-box?"

"Still in his bedroom."

"What a stroke of luck! Quick, madam, bring it here!"

A moment later she had appeared with a red flat box in her hand.

"How did you open it before? You have a duplicate key? Yes, of course
you have. Open it!"

From out of her bosom Lady Hilda had drawn a small key. The box flew
open. It was stuffed with papers. Holmes thrust the blue envelope deep
down into the heart of them, between the leaves of some other document.
The box was shut, locked, and returned to the bedroom.

"Now we are ready for him," said Holmes; "we have still ten minutes.
I am going far to screen you, Lady Hilda. In return you will spend
the time in telling me frankly the real meaning of this extraordinary
affair."

"Mr. Holmes, I will tell you everything," cried the lady. "Oh, Mr.
