Duponte ignored this. "I shall demonstrate the conclusion," he said. We two waited at the very edge of anticipation. But Duponte simply stood there. After a space of three and a half minutes, roughly, a regular stampede of hurried noises was heard nearby and there-I must reveal-came a piece of cake from around the corner, floating in the air, right near the nose of its rightful owner!

"The cake!" I pointed.

The confection was attached to a short string of some sort, and followed behind two small boys running headlong through the gardens. The man chased down the boy and untied his cake from its thief. He then ran back to us.

"Why, remarkable monsieur, you were entirely right! But how have you recovered my cake?" For a moment the man looked at Duponte suspiciously, as though he had been involved in some scheme. Duponte, seeing he would have no peace without explaining, offered this simple description of what had transpired.

Among the most popular attractions in the natural collections of the Jardin des Plantes was the exhibition of bears. Before being accosted by the cake-widower, Duponte had casually noticed that it was near the time in which the bears usually stirred from their sleep. This was also known by the many local devotees to these animals, and it was a daily occupation to try to make the waking bears perform various antics and climb the pole provided for them, an effort that often involved dangling some item of food into their pit by twine or string. Indeed, the vendors at the gates to the gardens sold as much of their wares for these purposes as for human nourishment. But since among the lovers of the bears who would come from miles away for this sport were many young boys, and since most of these gamins had no spare sous in their pockets for such delicacies, Duponte reasoned that as the man had turned to secure his umbrella at the sign of rain, one of these boys had snatched the cake on his way to the bears. Because the bench was quite high, and the boy short, the man, on turning around again, saw no one nearby and thought the source of the theft fantastic.

"Very well. But how did you know the cake would return, and at this very spot?" the man asked.

"You may have noticed," continued Duponte, seeming to talk more to himself than to either of us, "that upon entering the grounds of the gardens, there was a larger group of officers of the garden in the vicinity of the zoological attractions than usual. Perhaps you remember reading of one of the bears, ‘Martin,' having recently devoured a soldier who leaned over too far and fell into their domain."

"Indeed! I remember," said the man.

"No doubt these guards were stationed to prevent young men and boys from any longer climbing the parapets to get close to the monsters."

"Yes! You are likely right, monsieur!" The man stood open-mouthed.

"It might have been further essayed, then, that if a boy had in fact taken possession of your cake, the same lad would be turned away from his plan by these vigilant guardians within the first few minutes of the bears' stirring, and the bandit would return by the most direct path-a path which crosses the grounds where we now stand-to the attraction second in popularity only to the wells of the bears for this sort of spectator: I mean the wire house of the monkeys, who, at the delivery of a bright piece of cloth or item of food, could be made to chase one another in, presumably, a manner almost as enchanting as the bears' climbing of the pole. None of the other popular holdings, the wolves or the parrots, will make such an exhibition over one's cake."

As delighted by this explanation as if it had been his own, the grateful man, with a magnanimous air, invited us to share in his cake, even though it had been in the grubby hands of the boy and had since been made flat by the rain. I politely declined, but Duponte, after a moment of thought, accepted and sat with him upon a bench. They ate with great relish as I held the man's umbrella over them.

That evening, I met the same man at a crowded café near my hotel. The bright lights of the interior presented a dazzling effect. He was playing a game of dominoes with a friend, whom he dismissed when he saw me come in.

"Monsieur, bravely done," I said joyfully. "Quite well done!"

I had met this man the day before in the same Jardin des Plantes. He was one of the chiffonniers of Paris, men whose occupation was to search through the rubbish heaps put out from the houses of Paris. They would use sticks and baskets with great expertise to collect anything of remote value. "Bones, scraps of paper, linen, cloth, bits of iron, broken glass, broken china, corks of wine bottles…" he explained. These men were not vagrants; rather, they were registered for this activity with the police.

I had inquired of the fellow how much he collected each day.

"Under King Philippe," he said of the former monarch, "thirty sous'worth a day! But now, under the Republic, only fifteen." He explained, with a sad tone of nostalgia for the monarchy, "People throw away less bones and paper now! When there is no luxury we who are poor can do nothing."

I would remember his words strongly in the months to come.

Because he could legally ply his trade only between five and ten in the morning, and was bent on earning money, I thought he would be agreeable to the scheme I had conceived. I had instructed him that when he saw me walking with my companion the following afternoon, he should exclaim in our hearing over the loss of some object of value and beg Duponte for assistance. In this way, Duponte might be jolted into some small undertaking.

Now, at the café where we had agreed to meet, as my part of the bargain I informed the waiter that I would pay for the meal of my accomplice's choice. And what a meal! He called for the tout ensemble of the place: poulet en fricassée, ragout, cauliflower, bonbons, melons, cream cheese! As was the practice in France, each new item of food came with a new plate, for the French abhorred the American practice of mixing tastes-for instance, vegetables and the sauces of meat-on one plate. I watched his feast happily, for his performance at the gardens had pleased me greatly.

"I did not think, at first, cake would work," I admitted to him. "I thought it a strange choice! Yet you managed quite well with that boy."

"No, no, monsieur!" he said. "I had nothing to do with that boy. The cake was truly stolen from me!"

"What do you mean?" I asked.

The chiffonnier said that he had planned to position his umbrella in some concealed spot and report the missing umbrella to Duponte to fulfill our agreement. It had been during the time he searched for a hiding place for the umbrella near the bench that his cake had vanished.

"How did he know what happened to it?" he asked. "Had you told your friend to watch me that whole time?"

"Of course not!" I shook my head. "I wanted to see if he would solve the mystery, and that would spoil the experiment, wouldn't it!"

The incident had clearly weighed on his mind. "He is an odd stick. Yet I suppose when a body is hungry, he shall do what he must."

I reflected on this axiom after parting from the man. I had been too excited about Duponte's promising behavior to consider why Duponte had performed his task of analysis. Perhaps Duponte, who had skipped dinner, had just been hungry for the cake, his share of the spoils, all along.

This was hardly the end of that line of attempts on my part to provoke Duponte into renewing his abilities. I had brought from America the pamphlet of The Prose Romances of Edgar A. Poe. I marked the first page of "The Murders in the Rue Morgue" and left it for Duponte, hoping that his interests would be captured. I rejoiced when it seemed that all my tactics were having an impact. The first true indication that Duponte was changing in some extraordinary way came one evening when I followed him to Café Belge. Two or three times a week he would sit on a bench, ignoring the billiards games and the chatter, comfortably lost in the ugly bustle and brawls around him. I had followed him here before. Something seemed different as soon as I saw him this time. His glance had already become less vacant.
