And almost as though moved by an irresistible impulse, her face wearing an expression of something that resembled terror, she added in a tone so strange that I could not help recalling the horrible speeches of Brignolles:

“Au revoir, my friends—or adieu.”

CHAPTER II
IN WHICH THERE IS QUESTION OF THE CHANGING HUMORS OF JOSEPH ROULETABILLE

In returning alone from the station I could not help feeling some surprise at the singular sensation of sadness which oppressed me, and of the cause of which I had not the least idea. Since the affair at Versailles, with the details of which my existence had become so strangely intermingled, I had enjoyed the closest intimacy with Professor Stangerson, his daughter, and Robert Darzac. I ought to have been completely happy on the day of this wedding, which seemed in every way so satisfactory. I wondered whether the unexplained absence of the young reporter did not account in some measure for my strange depression. Rouletabille had been treated by the Stangersons and by M. Darzac as their deliverer. And especially since Mathilde had left the sanitarium, in which, for several months, her shattered nervous system had needed and received the most assiduous care—since the daughter of the famous professor had been able to understand the extraordinary part which the boy had played in the drama that, without his help, would inevitably have ended in the bitterest grief for all those whom she loved—since she had read by the light of her restored reason the short-hand reports of the trial, at which Rouletabille appeared at the last moment like some hero of a miracle—she had surrounded the youngster with an affection little less than maternal. She interested herself in everything which concerned him; she begged for his confidence; she wanted to know more about him than I knew, and, perhaps, more even than he knew himself. She had shown an unobtrusive but strong curiosity in regard to the mystery of his birth, of which all of us were ignorant, and on which the young man had kept silence with a sort of savage pride. Although he fully realized the tender friendship which the poor soul felt for him, Rouletabille maintained his reserve and in his dealings with her affected a formal politeness which astonished me, coming from the boy whom I had known so exuberant, so whole-hearted, so strong in his likes and dislikes. More than once I had mentioned the matter to him, and he had answered me in an evasive manner, laying great stress, however, upon his sentiments of devotion for “a lady whom he esteemed beyond anyone in the world, and for whom he would have been ready to sacrifice his all, if fate or fortune had given him anything to sacrifice for anyone.” He would take strange whims at such times. For instance, after having made, in my presence, a promise to take a holiday and remain all day with the Stangersons, who had rented for the summer (for they did not wish to live at the Glandier again) a pretty little place at Chennevieres, on the borders of the Marne, and after having shown an almost childish joy at the prospect, he suddenly and without any reason refused to accompany me. And I was obliged to set out alone, leaving him in his little room, in the corner of the Boulevard St. Michel and the Rue Monsieur-le-Prince. I wished as I departed that he might experience as much pain as I knew that he would cause Mlle. Stangerson. One Sunday, she, vexed at the lad’s behavior, made up her mind to go with me to his den in the Latin Quarter, and surprise him.

When we reached his lodgings, Rouletabille, who had answered our knock with an energetic “Come in,” sat working at a little table. He arose as we entered, and turned so pale that we believed that he was about to fall in a faint.

“Good heavens!” cried Mlle. Stangerson, hastening toward him. But he was quicker than she, and before she reached the table on which he leaned, he had thrown a cover over the papers which were spread over the surface, hiding them entirely.

Mathilde had, of course, noticed the action. She paused in amazement.

“We are disturbing you,” she said.

“Oh, not at all,” replied Rouletabille. “I have finished my work. I will show it to you sometime. It is a masterpiece—a piece in five acts, for which I am not able to find the denouement.”

And he smiled. Soon he was again entirely master of himself, and made us a hundred droll speeches, thanking us for having come to cheer him in his solitude. He insisted on inviting us to dinner, and we three ate our evening meal in a Latin Quarter restaurant—Foyot’s. It was a happy evening. Rouletabille telephoned for Robert Darzac, who joined us at dessert. At this time M. Darzac was not ill, and the amazing Brignolles had not yet made his appearance in Paris. We played like children. That summer night was so beautiful in the solitude of the Luxembourg!
