"It is her own," said the maid in a cold lifeless voice, "so it makes no difference which one of you use it. You will find her in the library."

As she was speaking she had slipped her latch key into the lock and had entered. Von Lertz followed in a semi-daze, and walked alone into the library.

"Madam Stephan, I have come to claim the debt you owe Imperial Germany," he said in a voice which he hardly recognized as his own. Mechanically he thrust the revolver toward her.

Madam Stephan started to her feet from the easy chair in which she had been reclining. One look at the pallid, set face of Von Lertz convinced her of the desperateness of her position. Life had become very sweet to her after her intimate talk with Harrison Grant. She made a sudden lunge at Von Lertz.

She had just reached him when there came the muffled report of a revolver shot smothered in clothing. Von Lertz had reversed the weapon and pulled the trigger. Madam Stephan staggered back and then fell full length on the floor, her life blood oozing out through a wound which had penetrated her heart.

As Von Lertz stood aghast gazing at the result of his handiwork the maid entered. She took the revolver from his nerveless hand and stooping by the body of her former mistress twisted the fingers of the right hand, already cooling in death, about the handle and the trigger. Then she walked to the table and picking up a book, opened it, and began marking a passage.

"This will be absolute proof of her suicide," she remarked calmly. "It occurred to me this afternoon. You know she had been reading Dickens, expecting to be ordered to England any day for work."

Von Lertz dully took the book which was extended to him. He recognized it as the copy of "A Tale of Two Cities," which he had examined but a few days previously. He saw the sentence which the maid had underlined:

"It is a far, far better thing I do, than I have ever done, it is a far, far better rest that I go to, than I have ever known."

He stood motionless as the maid took the book from him and placed it on the table where the message would be the first thing to catch the eye of an investigator.
