On the table, there was a pile of the yellow flyers I had seen outside. I picked one up.

"You are ready," I said. "You are ready! When did you have these printed, monsieur?"

"There is more to do first," said Duponte. "In the morning."

I read the flyer again. Duponte was announcing that he would present to the public a lecture explaining the death of Edgar A. Poe. The source for the celebrated character of Dupin, it read. The analyst of great fame in Paris, who sought out the infamous murderer of Monsieur Lafarge, the famous victim of poisoning, will present an exposition detailing all that happened to Edgar A. Poe on October 3d, 1849, in the city of Baltimore. All facts gathered by personal examination and reflection.

Presented free to the public.

The next morning, the day of Duponte's lecture, I left before Duponte woke in order to distribute more flyers. I placed them on many stores, gates, and poles. I had sent for Edwin and, after hearing about Duponte, he agreed to help spread the notices around various quarters of the city while out and about for his newspaper jobs. I handed the flyers to passersby and watched their faces react with interest as they read.

As a hand reached for one, I looked up into the stern face before me. He grabbed for the flyer.

Henry Herring narrowed his eyes at me over the top of the flyer. "Mr. Clark. What is this all about?"

"Everything will now be understood," I said, "about your cousin's death."

"I hardly consider myself a relation, to speak the truth."

"Then you need not concern yourself," I answered, taking the flyer back. "Yet you were enough of a relation to be one of the few people to watch his burial."

Herring's lips compressed into a tight line. "You do not understand him."

"You mean Poe?"

"Yes," he grumbled. "Do you know that when he lived here in Baltimore, before marrying Virginia, Eddie courted my daughter? Did your friend Eddie tell you of that infamous conduct? Wrote her poems, one after another, declaring his love," he said distastefully. "My Elizabeth!"

Herring starting clucking in the hollow of his cheek. By this time, though, my attention had drifted. Filled with the excitement of the day that was about to occur, I had been imagining the face of the Baron Dupin upon seeing the flyer-assuming the French assailants had not yet caught him. Henry Herring said a few more words to the effect that it seemed unsavory to pull up the affairs of a dead man from a dishonorable grave.

I stared out at a tree bough weaving in and out of the wind. Looking around, I saw Duponte's flyers in glorious abundance at every corner. That is what filled me with alarm.

If the Baron did know about Duponte's lecture and the flyers, would he not be sending Bonjour and whatever rascals he might hire to tear them down, or cover them with his own notices? He would at least do that. It would only be fair, from his perspective. But not a single one of the notices had been removed. Would the Baron allow that? Would he back out so easily…?Unless…

"The Baron!" I cried.

"Where in the deuce are you going?" Herring called out to me as I broke into a run.

"Monsieur? Monsieur Duponte!"

I called while still clutching the latch of my street door. I scurried through the front hall anxiously, climbed up the stairs, and rushed into the library. He was not there. I knew something had come to pass.

No, not Duponte.

I heard the light steps of Daphne in the hall with another servant. I ran after her and asked her where Duponte was.

She shook her head. She seemed frightened, or perhaps just bewildered. "His friends took him, Mr. Clark."

No, no, I thought, the words clutching my chest.

A young man had come to the door and said there was a caller for Mr. Duponte; but, he explained, the caller was lame, so Mr. Duponte would have to come to the gate to see him. The carriage was waiting there. Daphne replied that it would be better for the caller to come to the door, as was the custom. But the driver insisted. She informed Duponte and, after giving the matter some thought, he went.

"And then," I urged her to continue.

Daphne seemed to have softened her harsh stance against Duponte, as her eyes were blurred and she dabbed them before continuing. "There was a man sitting in the carriage like a king-I don't think he was lame at all, as he stood tall and took Mr. Duponte by the arm. And he-sir-"

"Yes?"

"He looked just like Mr. Duponte! As though exact twins, honor bright!" she vowed. "And Mr. Duponte went into the carriage, but with a quiver in his face that was sad. Like he knew he was leaving something behind, forever. How I wished you were here, Mr. Clark!"

I had been a simpleton, an ass! The Baron had not stopped our flyers for the lecture because he would stop the lecturer himself!

There was no trace of the Baron at the hotels, which I began calling on myself. First, I went to the police to report that Auguste Duponte was missing and gave them Von Dantker's formal portrait, which I had taken from the Baron. I also gave them a drawing I hastily sketched of the Baron and his colleagues, including the various drivers, porters, and messengers who I had noted had at one time or another been engaged by him. Later, I received a message that I was wanted at the station house.

The same Officer White whom I had spoken with at the time of Poe's death was waiting at his desk. His hands were folded tightly together in front of him.

"Have you found him now? Have you found Duponte?"

"Or Dupin?" he asked. "These portraits you gave us help, Mr. Clark. But the hotel clerks we interviewed all recognize Duponte not as Duponte, but as Dupin. You do notice their similarities even in the sketch you made with the painting?"

I could barely suppress my agitation. "The reason they appear similar is because Baron Dupin has been flagrantly attempting to ape Monsieur Duponte, and the artist, Von Dantker-he was part of it!"

White repositioned his hands and cleared his throat.

"Duponte was pretending to be Dupin?"

"What? No, no. Entirely the reverse, Officer White. Dupin wishes to prove he was the real source for Poe's character-"

"Poe again! Now, what has this to do with him?"

"A great deal! You see, Auguste Duponte is the model for the character of C. Auguste Dupin. That is why he has come. To resolve the mystery of the death of Poe. He has been living in my house and has busied himself at his labor; that is why he has not been seen very much at all. Not to mention he walks mostly in the evening-well, Poe's Frenchman does the same. In the meantime, the Baron Claude Dupin has pretended he is also the model of Dupin, as well as imitating Duponte."

Officer White put his hand up to stop me. "You are implying Duponte is Dupin."

"Yes! Well, it is much more complicated than that, isn't it? The Baron Dupin is trying to be C. Auguste Dupin. The important point is simply to find the man before he comes to harm."

"Perhaps, if I may suggest, you have simply seen this one fellow, Dupin, and mistaken him for someone else."

"Mistaken him…" I said, reading his meaning. "I have not imagined the entire existence of Auguste Duponte, sir. I have not imagined someone living and supping and shaving in my house!"

White shook his head and looked to the floor.

I went on in a deep and serious tone. "Dupin is the wire-puller of this. He must be stopped at all costs! He is dangerous, Officer White! He has kidnapped a rare genius and may have already brought him to injury. He will spread his false version of events behind Poe's death. Does none of that concern you?"
