The President seemed partly convinced, but still curious, he asked: “But what is this secret of Mademoiselle Stangerson?” “That I cannot tell you,” said Rouletabille. “I think, however, you know enough now to acquit Monsieur Robert Darzac! Unless Larsan should return, and I don’t think he _will_,” he added, with a laugh. “One question more,” said the President. “Admitting your explanation, we know that Larsan wished to turn suspicion on Monsieur Robert Darzac, but why should he throw suspicion on Daddy Jacques also?” “There came in the professional detective, Monsieur, who proves himself an unraveller of mysteries, by annihilating the very proofs he had accumulated. He’s a very cunning man, and a similar trick had often enabled him to turn suspicion from himself. He proved the innocence of one before accusing the other. You can easily believe, Monsieur, that so complicated a scheme as this must have been long and carefully thought out in advance by Larsan. I can tell you that he had long been engaged on its elaboration. If you care to learn how he had gathered information, you will find that he had, on one occasion, disguised himself as the commissionaire between the ‘Laboratory of the Sûreté’ and Monsieur Stangerson, of whom ‘experiments’ were demanded. In this way he had been able before the crime, on two occasions to take stock of the pavilion. He had ‘made up’ so that Daddy Jacques had not recognised him. And yet Larsan had found the opportunity to rob the old man of a pair of old boots and a cast-off Basque cap, which the servant had tied up in a handkerchief, with the intention of carrying them to a friend, a charcoal-burner on the road to Epinay. When the crime was discovered, Daddy Jacques had immediately recognised these objects as his. They were extremely compromising, which explains his distress at the time when we spoke to him about them. Larsan confessed it all to me. He is an artist at the game. He did a similar thing in the affair of the ‘Crédit Universel,’ and in that of the ‘Gold Ingots of the Mint.’ Both these cases should be revised. Since Ballmeyer or Larsan has been in the Sûreté a number of innocent persons have been sent to prison.” Chapter XXVIII In Which it is Proved That One Does not Always Think of Everything Great excitement prevailed when Rouletabille had finished. The court-room became agitated with the murmurings of suppressed applause. Maître Henri Robert called for an adjournment of the trial and was supported in his motion by the public prosecutor himself. The case was adjourned. The next day Monsieur Robert Darzac was released on bail, while Daddy Jacques received the immediate benefit of a “no cause for action.” Search was everywhere made for Frédéric Larsan, but in vain. Monsieur Darzac finally escaped the awful calamity which, at one time, had threatened him. After a visit to Mademoiselle Stangerson, he was led to hope that she might, by careful nursing, one day recover her reason.
