“And we will find the stolen articles,” said Monsieur Dax. “But what was in the cabinet?” “Twenty years of my life,” replied the illustrious professor sadly, “or rather of _our_ lives—the lives of myself and my daughter! Yes, our most precious documents, the records of our secret experiments and our labours of twenty years were in that cabinet. It is an irreparable loss to us and, I venture to say, to science. All the processes by which I had been able to arrive at the precious proof of the destructibility of matter were there—all. The man who came wished to take all from me,—my daughter and my work—my heart and my soul.” And the great scientist wept like a child. We stood around him in silence, deeply affected by his great distress. Monsieur Darzac pressed closely to his side, and tried in vain to restrain his tears—a sight which, for the moment, almost made me like him, in spite of an instinctive repulsion which his strange demeanour and his inexplicable anxiety had inspired me. Monsieur Rouletabille alone,—as if his precious time and mission on earth did not permit him to dwell in the contemplation on human suffering—had, very calmly, stepped up to the empty cabinet and, pointing at it, broke the almost solemn silence. He entered into explanations, for which there was no need, as to why he had been led to believe that a robbery had been committed, which included the simultaneous discovery he had made in the lavatory, and the empty precious cabinet in the laboratory. The first thing that had struck him, he said, was the unusual form of that piece of furniture. It was very strongly built of fire-proof iron, clearly showing that it was intended for the keeping of most valuable objects. Then he noticed that the key had been left in the lock. “One does not ordinarily have a safe and leave it open!” he had said to himself. This little key, with its brass head and complicated wards, had strongly attracted him,—its presence had suggested robbery. Monsieur de Marquet appeared to be greatly perplexed, as if he did not know whether he ought to be glad of the new direction given to the inquiry by the young reporter, or sorry that it had not been done by himself. In our profession and for the general welfare, we have to put up with such mortifications and bury selfish feelings. That was why Monsieur de Marquet controlled himself and joined his compliments with those of Monsieur Dax. As for Monsieur Rouletabille, he simply shrugged his shoulders and said: “There’s nothing at all in that!” I should have liked to box his ears, especially when he added: “You will do well, Monsieur, to ask Monsieur Stangerson who usually kept that key?” “My daughter,” replied Monsieur Stangerson, “she was never without it.”
