"But do you possess all the proofs?" asked Valenglay eagerly.

"Here they are," said Perenna, producing the pocket-book which he had taken out of the cripple's jacket. "Here are letters and documents which the villain preserved, owing to a mental aberration common to all great criminals. Here, by good luck, is his correspondence with Hippolyte Fauville. Here is the original of the prospectus from which I learned that the house on the Place du Palais-Bourbon was for sale. Here is a memorandum of Jean Vernocq's journeys to Alençon to intercept Fauville's letters to old Langernault.

"Here is another memorandum showing that Inspector Vérot overheard a conversation between Fauville and his accomplice, that he shadowed Vernocq and robbed him of Florence Levasseur's photograph, and that Vernocq sent Fauville in pursuit of him. Here is a third memorandum, which is just a copy of the two found in the eighth volume of Shakespeare and which proves that Jean Vernocq, to whom that set of Shakespeare belonged, knew all about Fauville's machination.

But there's one problem that remains unexplained, the one perhaps that interested the public most. I mean the marks of the teeth in the apple, the teeth of the tiger, as they have been called, which were certainly Mme. Fauville's teeth, innocent though she was. Monsieur le Préfet declares that you have solved this problem."

"Yes, Monsieur le Président, and Jean Vernocq's papers prove that I was right. Besides, the problem is quite simple. The apple was marked with Mme. Fauville's teeth, but Mme. Fauville never bit the apple."
