My uncle in his letters spoke of nothing but the Yard. The works were making quick progress. The amphitheatre was growing taller and taller. The wall was quite transformed. The last news, about the middle of March, told me that nothing remained to be done but to fix the thousand seats, which had long been on order, and to hang the iron curtain which was to protect the screen. It was at this period that Noël Dorgeroux's misgivings revived, or at least it was then that he mentioned them when writing to me. Two books which he bought in Paris and which he used to read in private, lest his choice of a subject should enable anyone to learn the secret of his discovery, had been removed, taken away and then restored to their place. A sheet of paper, covered with notes and chemical formulae, disappeared. There were footprints in the garden. The writing-desk had been broken open, in the room where he worked at the Lodge since the demolition of the sheds. This last incident, I confess, caused me a certain alarm. My uncle's fears were shown to be based upon a serious fact. There was evidently some one prowling around the Lodge and forcing an entrance in pursuance of a scheme whose nature was easy to guess. Involuntarily I thought of the man with the glasses and his relations with Bérangère. There was no knowing. . . . I made a fresh attempt to persuade the girl to communicate with me: * * * * * "You know what's happening at the Lodge, don't you?" I wrote. "How do you explain those facts, which to me seem pretty significant? Be sure to send me word if you feel the least uneasiness. And keep a close watch in the meantime." I followed up this letter with two telegrams dispatched in quick succession. But Bérangère's stubborn silence, instead of distressing me, served rather to allay my apprehensions. She would not have failed to send for me had there been any danger. No, my uncle was mistaken. He was a victim to the feverish condition into which his discovery was throwing him. As the date approached on which he had decided to make it public, he felt anxious. But there was nothing to justify his apprehensions. I allowed a few more days to elapse. Then I wrote Bérangère a letter of twenty pages, filled with reproaches, which I did not post. Her behaviour exasperated me. I suffered from a bitter fit of jealousy. At last, on Saturday, the twenty-ninth of March, I received from my uncle a registered bundle of papers and a very explicit letter, which I kept and which I am copying _verbatim_: "MY DEAR VICTORIEN,
