"If I do examine the affair of her sister's death," Duponte began, and the Baron thrilled at those words, "if I do so, I would not wish others to know of my involvement."

The Baron promised not to talk to the press about Duponte's assistance.

Duponte did investigate the Gautier sister's death, as promised. He promptly discovered, with no trace of a doubt, the chronicle of events that led to the murder. His conclusions pointed indisputably at his lover, Catherine Gautier, as the perpetrator. He passed on his information to the prefect, producing a witness undetected by the police and ruining all of Baron Dupin's chances to win by other means. This turn made the Baron more desperate. He was too proud to accept defeat gracefully. He expended many favors, and many thousand francs beyond what was already a deepening debt, to manipulate the case. But it was to no effect. Duponte's evidence was too strong to be tarnished. The Baron was now ruined in his finances and reputation.

Meanwhile, Officer Delacourt, ambitious to advance in the prefecture, assured Duponte and Gautier that with the new evidence, which painted the young woman as confused and deluded but by no means demonic, and taking into account her sex, there would be leniency in her sentencing. And yet, a few months later she was executed, with Dupin and Duponte, along with three-quarters of Paris, attending.

"First of all," I said, "it was Duponte more than you who suffered in this matter. Not only did it sap him of an ability to pursue the work of his genius, he also lost the one woman he loved-at his own hands! You shall not avenge yourself for your disgrace by plaguing Duponte now. You cannot use Poe's death for that purpose. I shall not stand by!"

The Baron retorted, "Recollect that fine legal axiom super subjectum materiam: no man can be held professionally responsible for opinions which have been founded on the facts submitted to him by others." The Baron stood over my chair. "I didn't start this, monsieur. You did. You prompted me to look into Poe's fall. You stand in your own light, do you realize it? Feel your oats, Brother Quentin! You made me see that I could renew myself. My name was crushed by detractors and defamers because the shadow of my genius grew too large and refused to conform to their small lives, so the eyes upon us make every small peccadillo into a mortal sin to stop me-why, it is like our dear Poe."

"Will you compare yourself to Poe?" I asked, openly aghast.

"I do not have to, because Brother Poe has already. Why do you think he chose the character of Dupin as his finest hero? He saw in the genius of the decipherer his own divine abilities to understand what gods and men could never fathom. And with what credit? The prefect of the police, not the hero Dupin, receives the praise of all parties. Even as other writers half as good as Poe found themselves winning gold from the magazines, Poe struggled one last time to overcome adversity, struggled until the end, until finally cut-from existence."

"Do you truly believe, monsieur, that you are worthy as the model for Dupin?"

"You did, before having the misfortune to find Duponte, seduced by talents that he uses only for his own interests. Duponte is an anarchist. Have you ever, since meeting him, had any doubts that…perhaps…" He stretched out the words. "Perhaps you know there was another reason I gave you leave to act the spy on us, my friend. So you might see first-hand, Brother Quentin, that you passed something up in Paris, at the fortifications, when you chose him over me."

I wondered if he knew-if the Baron had had someone observing me when I had come to what I thought was his hotel that night. That free black standing under the lamp? "Duponte is the one. You cannot hold a candle to him," I said. I could not let him have the mental victory of knowing how close I had come to giving up hope in Duponte only a few days earlier. I think my expression might have been transparent, though.

"Well," he said, smiling a little, "only Edgar A. Poe could answer who the original Dupin is, and he is gone. How does one solve something when the solution is unreachable? The real Dupin is whoever convinces the world of it; he shall be the remaining one."

I FOUND MYSELF fearing Duponte for the first time. Wondering if-indeed-his talents, when released unrestrained and unharnessed, could turn disastrous, as they had against Mademoiselle Gautier. I could not help calling to mind the finale of "The Gold-Bug," Poe's rousing tale of a hunt for treasure-it had always seemed to me, rumbling beneath the surface, that in the triumphant ending there was the clue that Legrand, the master thinker, was about to murder his servant and his friend now that their mission was achieved. The last ominous words of that story-"Who shall tell?"-reverberated in my head.

I called to mind one peculiar evening during my stay in Paris. I was walking behind Auguste Duponte into an area of the city Madame Fouché had warned was not safe at night. Your cries, Madame Fouché had said, would bring no police, who are often in league with the bad people. I remember I was stopped by an object inside a store window that seemed to shift as though on its own power. There was a circle of artificial jaws representing every state of the human mouth: one with bright gums and spotless milky teeth, another with decayed and wilting gums, and so on. Each rotated and opened and shut at different speeds through some unseen mechanical ingenuity. Above the jaws were revolving wax heads showing a toothless, collapsed face and then one boasting a fresh and sturdy mouth with shining teeth, presumably repaired by a dentist with his office behind this window.

Before I could pull myself away from the mesmerizing sight, I felt a tightness around my ears. Everything went black. My hat had been thrust down over my eyes to blind me, and I could feel hands burrowing into my coat from behind. As I cried out for help, I managed to knock the narrow portion of my hat up from my eyes. I saw an old woman with a threadbare dress of rags and blackened teeth. After having tried to blind me with my hat to rob me, she had stepped back and now only stood staring. I followed her gaze to Duponte, standing a few feet from the attacker. Once she had run off, I turned gratefully to Duponte. What had so frightened her away? If he knew, he never shared it with me.

I now considered that the wretched being must have recognized Duponte from a former era. A criminal enterprise that Duponte must have spoiled-perhaps she had once been part of some grand assassination plan (for it was said of Duponte that in his time he had uncovered more than one plan to kill the head of France) and, in consequence of his acumen long ago, was in the interim reduced to animal desperation. It was no physical fear of Duponte that had prompted her flight from me. She could have thrust a blade through my heart ten times before Duponte stopped her (if stopping her was his intention). It was not fear of his strength or agility. It was raw, impulsive fear of his pure intellect-a fear of his genius.

Who shall tell?

After leaving the Baron's hotel, I found Duponte sitting by the large window in the drawing room of Glen Eliza, intently facing the door. I began to tell him all that had occurred at Barnum's Hotel.

"Take this," Duponte interrupted, holding up a leather bag. "Bring it to the address on this paper." He handed me a slip of paper.

"Monsieur, have you not listened to the intelligence I bring? Baron Dupin-"

"You must go out at once, Monsieur Clark," he said. "It is time."

I looked down at the address and did not recognize it. "Very well… What should I say once I arrive?"
