Lupin was easier in his mind after these revelations. Nevertheless, he was pursued by stubborn notions which he was unable either to drive from his brain or to put into words. Above all, he thought incessantly of that name of “Marie” which Daubrecq’s sufferings had drawn from him. What did the name refer to? Was it the title of one of the books on the shelves, or a part of the title? Would the book in question supply the key to the mystery? Or was it the combination word of a safe? Was it a series of letters written somewhere: on a wall, on a paper, on a wooden panel, on the mount of a drawing, on an invoice?

These questions, to which he was unable to find a reply, obsessed and exhausted him.

One morning Arsène Lupin woke feeling a great deal better. The wound was closed, the temperature almost normal. The doctor, a personal friend, who came every day from Paris, promised that he might get up two days later. And, on that day, in the absence of his accomplices and of Mme. Mergy, all three of whom had left two days before, in quest of information, he had himself moved to the open window.

He felt life return to him with the sunlight, with the balmy air that announced the approach of spring. He recovered the concatenation of his ideas; and facts once more took their place in his brain in their logical sequence and in accordance with their relations one to the other.

In the evening he received a telegram from Clarisse to say that things were going badly and that she, the Growler and the Masher were all staying in Paris. He was much disturbed by this wire and had a less quiet night. What could the news be that had given rise to Clarisse’s telegram?

But, the next day, she arrived in his room looking very pale, her eyes red with weeping, and, utterly worn out, dropped into a chair:

“The appeal has been rejected,” she stammered.

He mastered his emotion and asked, in a voice of surprise:

“Were you relying on that?”

“No, no,” she said, “but, all the same . . . one hopes in spite of one’s self.”
