Ballmeyer was the best specimen of the high-class “gentleman swindler.” He was an adept at sleight of hand tricks, and no bolder or more ruthless crook ever lived. He was received in the best society, and was a member of some of the most exclusive clubs. On many of his depredatory expeditions he had not hesitated to use the knife and the mutton-bone. No difficulty stopped him and no “operation” was too dangerous. He had been caught, but escaped on the very morning of his trial, by throwing pepper into the eyes of the guards who were conducting him to Court. It was known later that, in spite of the keen hunt after him by the most expert of detectives, he had sat that same evening at a first performance in the Théâtre Français, without the slightest disguise. He left France, later, to “work” America. The police there succeeded in once capturing him, but the extraordinary man escaped the next day. It would need a volume to recount the adventures of this master-criminal. And yet this was the man Rouletabille had allowed to get away! Knowing all about him and who he was, he afforded the criminal an opportunity for another laugh at the society he had defied! I could not help admiring the bold stroke of the young journalist, because I felt certain his motive had been to protect both Mademoiselle Stangerson and rid Darzac of an enemy at the same time. The crowd had barely recovered from the effect of the astonishing revelation when the hearing was resumed. The question in everybody’s mind was: Admitting that Larsan was the murderer, how did he get out of The Yellow Room? Rouletabille was immediately called to the bar and his examination continued. “You have told us,” said the President, “that it was impossible to escape from the end of the court. Since Larsan was leaning out of his window, he had left the court. How did he do that?” “He escaped by a most unusual way. He climbed the wall, sprang onto the terrace, and, while we were engaged with the keeper’s body, reached the gallery by the window. He then had little else to do than to open the window, get in and call out to us, as if he had just come from his own room. To a man of Ballmeyer’s strength all that was mere child’s play. And here, Monsieur, is the proof of what I say.” Rouletabille drew from his pocket a small packet, from which he produced a strong iron peg.
