Those Parisians who flocked 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 Frédéric 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 Frédéric 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 rumour spread that Monsieur Stangerson himself had been arrested in the court and had confessed to being the murderer. This goes to show to what a pitch of madness nervous excitement may carry people. Rouletabille was still expected. Some pretended to know him; and when a young man with a “pass” crossed the open space which separated the crowd from the Court House, a scuffle took place. Cries were raised of “Rouletabille!—there’s Rouletabille!” The arrival of the manager of the paper was the signal for a great demonstration. Some applauded, others hissed. * * * * * The trial itself was presided over by Monsieur de Rocouz, a judge filled with the prejudice of his class, but a man honest at heart. The witnesses had been called. I was there, of course, as were all who had, in any way, been in touch with the mysteries of the Glandier. Monsieur Stangerson—looking many years older and almost unrecognisable—Larsan, Arthur Rance, with his face ruddy as ever, Daddy Jacques, Daddy Mathieu, who was brought into court handcuffed between two gendarmes, Madame Mathieu, in tears, the two Berniers, the two nurses, the steward, all the domestics of the château, the employé of the Paris Post Office, the railway employé from Epinay, some friends of Monsieur and Mademoiselle Stangerson, and all Monsieur Darzac’s witnesses. I was lucky enough to be called early in the trial, so that I was then able to watch and be present at almost the whole of the proceedings.
