"Everything, in short, led him to think that things would go according to the 'hater's' wishes, when something occurred that nearly upset his schemes: the appearance of Inspector Vérot, who had been sent by you, Monsieur le Préfet, to collect particulars about the Mornington heirs. What happened between the two men? Probably no one will ever know. Both are dead; and their secret will not come to life again. But we can at least say for certain that Inspector Vérot was here and took away with him the cake of chocolate on which the teeth of the tiger were seen for the first time, and also that Inspector Vérot succeeded, thanks to circumstances with which we are unacquainted, in discovering M. Fauville's projects."
"This we know," explained Don Luis, "because Inspector Vérot said so in his own agonizing words; because it was through him that we learned that the crime was to take place on the following night; and because he had set down his discoveries in a letter which was stolen from him.
"And Fauville knew it also, because, to get rid of the formidable enemy who was thwarting his designs, he poisoned him; because, when the poison was slow in acting, he had the audacity, under a disguise which made him look like Sauverand and which was one day to turn suspicion against Sauverand, he had the audacity and the presence of mind to follow Inspector Vérot to the Café du Pont-Neuf, to purloin the letter of explanation which Inspector Vérot wrote you, to substitute a blank sheet of paper for it, and then to ask a passer-by, who might become a witness against Sauverand, the way to the nearest underground station for Neuilly, where Sauverand lived! There's your man, Monsieur le Préfet."
