"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_.

"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.

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."
