"Listen," said Monte-Leone, "the signature of Ober is false, but perhaps it is the only one which has been counterfeited. We must ascertain whether the others are. This point must be cleared up, and I will see to it. Gold and influence will open the dungeons of our friends, and I will see them. Besides, the papers were not out of my possession. Ah!" said he, as if he were utterly discouraged, "this is enough to make a man mad. To-morrow I shall have penetrated it, and then you will see me." He went out through the secret pannel.

When it had closed, Apsberg arose and repeating his last words, said, "Yes, my friends, to-morrow you shall know all." Taking from his bosom the letter Mlle. Crepineau had given him, he read as follows:

"To Doctor Matheus—If you would ascertain who has denounced your brethren, the miserable spy whose reports have ruined them and given to your enemies the original rolls, be to-night at 11 o'clock, p. m., at the back door of the Prefecture of Police, opening on the quai des Orfevres. You will there find the person you need. This is the hour of his rendezvous. Stand in the angle of the door, and without being seen, you may recognize the informer.

"A Brother of the third Central Vente."

V.—A TERRIBLE NIGHT.

The night of January 5th, 1820, was one of the coldest of the winter. The snow fell heavily, and the Seine was covered with large crystallized flakes which, uniting together and lodging on each bank, narrowed the current and caused it to flow more rapidly.

The steps of the patrols, or of the benighted travellers, were unheard. The light of the lamps shone redly but indistinctly amid the snowy cloak which hung around them. They seemed like eyes of fire in the long solitary streets. All was sad and gloomy in this paradise of pleasure and festival. One might have fancied a vast white shroud to be extended over a city without souls.

A man walked rapidly down the port St. Nicholas, before that part of the old Louvre which had once witnessed such joy, love, crime, and splendor. His steps seemed, from their length, to testify great impatience and an anxiety to reach his destination.

"What can they be about?" said he. "All is lost if they do not come. The anonymous note is formal and the terms are precise, "Eleven o'clock and the quai des Orfevres." This secret enemy, whose name and features we are about to know, had only to hasten to the Prefecture of Police to deprive us of the only means of unmasking a scoundrel. Yet heaven protects us, for just as I was about to reveal to Monte-Leone the villainy imputed to him, this note closed my lips and veiled the indignation my words could not but have created in his noble soul."

The man stopped. The silence of the quai was broken, and he heard the sound of persons approaching him. Soon two shadows were seen by the light of the lamps which hung from the walls of the Louvre, and a voice was heard. "It is he: it is Matheus. He waits for us in the chiaro oscuro of the door." This was followed by a short dry cough, produced by the intense cold of the evening. The speaker was the Vicomte d'Harcourt, scarcely recovered from his illness. A few seconds passed and d'Harcourt and Taddeo stood by the side of Von Apsberg. The three friends had determined not to consult Monte-Leone, nor to inform him of what had taken place until they knew who had denounced them and who was to be punished.
