“Well,” said he, “I will give up this idea; but how do I know that these documents are not forgeries? Nowadays, handwritings are easily facsimilied, when even bankers find it hard to distinguish between their own notes and counterfeit ones.”

“That can be settled by seeing if certain leaves are missing from the Baron’s diary.”

“That does not prove much.”

“Pardon me, it proves a great deal. This new line of argument, I assure you, will avail you as little as the other. I am perfectly aware that the Baron de Clinchain will utter whatever words you may place in his mouth. Let us suppose that the leaves which have been torn out should fit into the book exactly. Would not that be a strong point?”

The Count smiled ironically, as though he had a crushing reply in reserve.

“And so this is your opinion, is it?” said he.

“It is indeed.”

“Then all I have to do is to plead guilty. I did kill Montlouis, just as Clinchain describes, but——” and as he spoke he took a heavy volume from a shelf, and opening it at a certain place laid it before Mascarin, remarking,—“this is the criminal code; read. ‘All proceedings in criminal law shall be cancelled after a lapse of ten years.’”

The Count de Mussidan evidently thought that he had crushed his adversary by this shattering blow; but it was not so, for instead of exhibiting any surprise, Mascarin’s smile was as bland as ever.

“I, too, know a little of the law,” said he. “The very first day this matter was brought to me, I turned to this page and read what you have just shown me to my employers.”
