By whose hands, for what cause, in what manner the world had lost that excellent man, no one could say. A great variety of theories prevail on the subject. He had sent the old servant for Pierre la Roche, whom he employed as a messenger, and he had given him at about a quarter to eleven a note addressed to David Arden, Esquire, which was no doubt that which Mr. Arden had received.

Had Heaven decreed that this investigation should come to naught? This blow seemed irremediable.

David Arden, however, had, as I mentioned, official friends, and it struck him that he might through them obtain access to the rooms in which his interviews with the baron had taken place; and that an ingenious and patient artist in plaster might be found who would search out the matrices, or, at worst, piece the fragments of the mask together, and so, in part, perhaps, restore the demolished evidence. It turned out, however, that the destruction of these relics was too complete for any such experiments; and all that now remained was, upon the baron's letter of the evening before, to move in official quarters for a search for those “matrices” from which it was alleged the masks were taken.

This subject so engrossed his mind, that it was not until after his late dinner that he began once more to think of Monsieur St. Ange, and his resemblance to Mr. Longcluse; and a new suspicion began to envelope those gentlemen in his imagination.

“Pray telegraph immediately to say whether Mr. Longcluse is at his house, Bolton Street, Piccadilly.”

No answer reached him that night; but in the morning he found a telegram dated 11.30 of the previous night, which said—

To this promptly he replied—

“See him, if possible, immediately at Richmond, and say how he looks. The surrender of the lease in Crown Alley will be an excuse. See him if there. Ascertain with certainty where. Telegraph immediately.”

No answer had reached Uncle David at three o'clock P.M.; he had despatched his message at nine. He was impatient, and walked to the telegraph office to make inquiries, and to grumble. He sent another message in querulous and peremptory laconics. But no answer came till near twelve o'clock, when the following was delivered to him:—
