I was writing in my office in the rue Madeleine when Andrée, my secretary, announced the arrival of Herr D_____. I rose, put away my correspondence, and offered him my hand. He was, I should say, just short of fifty, had the high, clear complexion characteristic of those who in youth (now unhappily past for both of us) have found more pleasure in the company of horses and dogs and the excitement of the chase than in the bottles and bordels of city life, and wore a beard and mustache of the style popularized by the late emperor. Accepting my invitation to a chair, he showed me his papers.
"You see," he said, "I am accustomed to acting as the representative of my government. In this matter I hold no such position, and it is possible that I feel a trifle lost."
"Many people who come here feel lost," I said. "But it is my boast that I find most of them again. Your problem, I take it, is purely a private matter?"
"Not at all. It is a public matter in the truest sense of the words."
"Yet none of the documents before me—admirably stamped, sealed, and beribboned though they are—indicates that you are other than a private gentleman traveling abroad. And you say you do not represent your government. What am I to think? What is the matter?"
"I act in the public interest," Herr D_____ told me. "My fortune is not great, but I can assure you that in the event of your success you will be well recompensed; although you are to take it that I alone am your principal, yet there are substantial resources available to me."
"Perhaps it would be best if you described the problems to me?"
"You are not averse to travel?"
"No."
"Very well then," he said, and so saying launched into one of the most astonishing relations—no, the most astonishing relation—I have ever been privileged to hear. Even I, who had at first hand the account of the man who found Paulette Renan with the quince seed still lodged in her throat; who had received Captain Brotte's testimony concerning his finds amid the Antarctic ice; who had heard the history of the woman called Joan O'Neal, who lived for two years behind a painting of herself in the Louvre, from her own lips—even I sat like a child while this man spoke.
When he fell silent, I said, "Herr D_____, after all you have told me, I would accept this mission though there were not a sou to be made from it. Perhaps once in a lifetime one comes across a case that must be pursued for its own sake; I think I have found mine."
