"Listen to me," said George. "I will explain everything;" and thereupon he gave Albert a substantial account of all he knew; the dropping of the pocket-book into the cab; the lunch at the Lion d'Or; the finding of Dargental's dead body; Puymirol's determination to discover the writers of the letters contained in the pocket-book; his subsequent disappearance, his attempt to cash a winning lottery ticket, his arrest, and the search made in the Rue de Medicis. "It was very foolish on Puymirol's part," he added, "for him to conceive the idea of conducting an investigation instead of reporting the facts to the authorities; but it was in vain that I represented to him that he would place himself in a very dangerous position. He first went to the house of the Countess de Lescombat. Ah! I forgot to tell you that one of the letters found in the pocket-book had evidently come from her."

"And was one of the others from Blanche?" asked Albert.

"Yes," replied Mademoiselle Pornic, promptly, "and I will explain it after you have read it. Monsieur Caumont can show it to you."

"Are the letters in your possession?" asked the young officer, looking searchingly at George.

"I have had them for two days past. Puymirol, before calling upon the countess, intrusted them to my keeping, and I have not been able to return them, as I have not seen him since."

"Read my letter," insisted Blanche.

"Are you willing to show it to me?" inquired Albert.

"Perfectly willing," replied George, "and the two others also. Besides, I want your advice in this matter; but it must be given with a full knowledge of all the circumstances. Here are the letters," he added holding them out. "Begin with Mademoiselle Pornic's. The top one won't be interesting to you, as we have no clue to the writer."

"It is very strange," exclaimed the officer, "but I am almost sure that I recognise the handwriting." And at the same time he turned very pale. George looked at him in surprise, and was suddenly seized with the idea that the third missive must have been written by some one closely connected with his future brother-in-law. Accordingly he hastily slipped it between the others, and lowered his hand. He had not been mistaken, for Albert, in a voice husky with emotion, resumed: "I am wrong of course, but give me the letter. I should like to examine it more closely. Why do you hesitate? You must know who wrote it?"

"No! I swear I don't."
