he banners of France. The English began to fall back, and
the emperor had already exclaimed: 'We have them!' when suddenly on the
right, a little in the rear, a large body of troops was seen advancing.
It was the Prussian army. The battle of Waterloo was lost."

In all his life, worthy Father Absinthe had never made such a strenuous
effort to understand anything. In this case his perseverance was not
wholly useless, for, springing from his stool, and probably in much the
same tone that Archimedes cried "Eureka!" he exclaimed, "I understand.
The man's words were only an allusion."

"It is as you have said," remarked Lecoq, approvingly. "But I had
not finished. If the emperor was thrown into consternation by the
appearance of the Prussians, it was because he was momentarily
expecting the arrival of one of his own generals from the same

A triumphant smile parted Lecoq's lips. "That is what I said to myself,"
he replied, "and now it is easy to verify my suspicions. There is snow
outside, isn't there?"

It was not necessary to say any more. The elder officer seized the
light, and followed by his companion, he hastened to the back door of
the house, which opened into a small garden. In this sheltered enclosure
the snow had not melted, and upon its white surface the dark stains
of numerous footprints presented themselves. Without hesitation,
