"Is that all you know?" Duvall inquired pointedly. "Surely the recovery of an article of so little consequence cannot be the real purpose of our visit."

The little old man shrugged his shoulders, with an almost imperceptible gesture of dissent. "I know nothing of the matter, monsieur," he remarked, significantly, "except that my country has called me, and that I am here." He spoke the words proudly, as though he considered the fact that he had been called upon an honor.

"But surely, you must have some idea, monsieur, of your purpose in being here?"

"Yes. That is indeed quite simple. On one occasion I was called upon to repair the snuff box of Monsieur de Grissac, the Ambassador. In that way I am familiar with its appearance. Now that it is lost, I am requested to accompany you, monsieur, in your attempt to recover it, in order that I may assist you in identifying it."

"And beyond that, you know nothing?"

"Nothing, monsieur."

Duvall began to chew the end of his cigar in vexation. Of all the absurd expeditions, this seemed the most absurd. Presently he turned to Dufrenne and again spoke. "In your repairs upon this snuff box, to which so great a value is apparently attached, did you observe anything about it of a peculiar nature—anything to make its loss a matter of such grave importance?"

"Nothing, monsieur. It is a small, round ivory box, with a carved top, quite plain and of little value—"

"But the contents? What, perhaps, did Monsieur de Grissac carry within it?"

"Snuff, monsieur. It was quite half-full when it came to me, last April. Monsieur de Grissac was in Paris at the time. The spring which actuates the top had become broken—the box is very old, monsieur—and I was required to repair it. That is all I know."
