On the 15th of January, that is to say, two months and a half after the tragic events I have narrated, the “Epoque” printed, as the first column of the front page, the following sensational article: “The Seine-et-Oise jury is summoned to-day to give its verdict on one of the most mysterious affairs in the annals of crime. There never has been a case with so many obscure, incomprehensible, and inexplicable points. And yet the prosecution has not hesitated to put into the prisoner’s dock a man who is respected, esteemed, and loved by all who knew him—a young savant, the hope of French science, whose whole life has been devoted to knowledge and truth. When Paris heard of Monsieur Robert Darzac’s arrest a unanimous cry of protest arose from all sides. The whole Sorbonne, disgraced by this act of the examining magistrate, asserted its belief in the innocence of Mademoiselle Stangerson’s fiance. Monsieur Stangerson was loud in his denunciation of this miscarriage of justice. There is no doubt in the mind of anybody that could the victim speak she would claim from the jurors of Seine-et-Oise the man she wishes to make her husband and whom the prosecution would send to the scaffold. It is to be hoped that Mademoiselle Stangerson will shortly recover her reason, which has been temporarily unhinged by the horrible mystery at the Glandier. The question before the jury is the one we propose to deal with this very day.

“We have decided not to permit twelve worthy men to commit a disgraceful miscarriage of justice. We confess that the remarkable coincidences, the many convicting evidences, and the inexplicable silence on the part of the accused, as well as a total absence of any evidence for an alibi, were enough to warrant the bench of judges in assuming that in this man alone was centered the truth of the affair. The evidences are, in appearance, so overwhelming against Monsieur Robert Darzac that a detective so well informed, so intelligent, and generally so successful, as Monsieur Frederic Larsan, may be excused for having been misled by them. Up to now everything has gone against Monsieur Robert Darzac in the magisterial inquiry. To-day, however, we are going to defend him before the jury, and we are going to bring to the witness stand a light that will illumine the whole mystery of the Glandier. For we possess the truth.

“If we have not spoken sooner, it is because the interests of certain parties in the case demand that we should take that course. Our readers may remember the unsigned reports we published relating to the ‘Left foot of the Rue Oberkampf,’ at the time of the famous robbery of the Credit Universel, and the famous case of the ‘Gold Ingots of the Mint.’ In both those cases we were able to discover the truth long before even the excellent ingenuity of Frederic Larsan had been able to unravel it. These reports were written by our youngest reporter, Joseph Rouletabille, a youth of eighteen, whose fame to-morrow will be world-wide. When attention was first drawn to the Glandier case, our youthful reporter was on the spot and installed in the chateau, when every other representative of the press had been denied admission. He worked side by side with Frederic Larsan. He was amazed and terrified at the grave mistake the celebrated detective was about to make, and tried to divert him from the false scent he was following; but the great Fred refused to receive instructions from this young journalist. We know now where it brought Monsieur Robert Darzac.

“But now, France must know—the whole world must know, that, on the very evening on which Monsieur Darzac was arrested, young Rouletabille entered our editorial office and informed us that he was about to go away on a journey. ‘How long I shall be away,’ he said, ‘I cannot say; perhaps a month—perhaps two—perhaps three perhaps I may never return. Here is a letter. If I am not back on the day on which Monsieur Darzac is to appear before the Assize Court, have this letter opened and read to the court, after all the witnesses have been heard. Arrange it with Monsieur Darzac’s counsel. Monsieur Darzac is innocent. In this letter is written the name of the murderer; and—that is all I have to say. I am leaving to get my proofs—for the irrefutable evidence of the murderer’s guilt.’ Our reporter departed. For a long time we were without news from him; but, a week ago, a stranger called upon our manager and said: ‘Act in accordance with the instructions of Joseph Rouletabille, if it becomes necessary to do so. The letter left by him holds the truth.’ The gentleman who brought us this message would not give us his name.

“To-day, the 15th of January, is the day of the trial. Joseph Rouletabille has not returned. It may be we shall never see him again. The press also counts its heroes, its martyrs to duty. It may be he is no longer living. We shall know how to avenge him. Our manager will, this afternoon, be at the Court of Assize at Versailles, with the letter—the letter containing the name of the murderer!”

Those Parisians who flocked to the Assize Court at Versailles, to be present at the trial of what was known as the “Mystery of The Yellow Room,” will certainly remember the terrible crush at the Saint-Lazare station. The ordinary trains were so full that special trains had to be made up. The article in the “Epoque” had so excited the populace that discussion was rife everywhere even to the verge of blows. Partisans of Rouletabille fought with the supporters of Frederic Larsan. Curiously enough the excitement was due less to the fact that an innocent man was in danger of a wrongful conviction than to the interest taken in their own ideas as to the Mystery of The Yellow Room. Each had his explanation to which each held fast. Those who explained the crime on Frederic Larsan’s theory would not admit that there could be any doubt as to the perspicacity of the popular detective. Others who had arrived at a different solution, naturally insisted that this was Rouletabille’s explanation, though they did not as yet know what that was.

With the day’s “Epoque” in their hands, the “Larsans” and the “Rouletabilles” fought and shoved each other on the steps of the Palais de Justice, right into the court itself. Those who could not get in remained in the neighbourhood until evening and were, with great difficulty, kept back by the soldiery and the police. They became hungry for news, welcoming the most absurd rumours. At one time the r............
