The extraordinary accuracy of Mr. Keller's memory was proverbial in the office. Remembering the compliment which he had paid to her sense of responsibility as Mr. Engelman's successor, Mrs. Wagner was not quite satisfied to take it for granted that he had made a mistake—even on the plain evidence of the ledger. A reference to the duplicate entry, in her private account-book, would at once remove even the shadow of a doubt.

The last day of the old year was bright and frosty; the clear midday light fell on the open page before her. She looked again at the entry, thus recorded in figures—"15,000 florins"—and observed a trifling circumstance which had previously escaped her.

The strokes which represented the figures "15" were unquestionably a little, a very little, thicker than the strokes which represented the three zeros or "noughts" that followed. Had a hair got into the pen of the head-clerk, who had made the entry? or was there some trifling defect in the paper, at that particular part of the page?

She once more raised one side of the ledger so that the light fell at an angle on the writing. There was a difference between that part of the paper on which the figures "15" were written, and the rest of the page—and the difference consisted in a slight shine on the surface.

The side of the ledger dropped from her hand on the desk. She left the office, and ran upstairs to her own room. Her private account-book had not been wanted lately—it was locked up in her dressing-case. She took it out, and referred to it. There was the entry as she had copied it, and compared it with the ledger—"20,000 florins."

"Madame Fontaine!" she said to herself in a whisper.

CHAPTER XI

The New Year had come.

On the morning of the second of January, Mrs. Wagner (on her way to the office at the customary hour) was stopped at the lower flight of stairs by Madame Fontaine—evidently waiting with a purpose.
