Disappearance of Colonel Ardenti

The Disappearance of Colonel Ardenti is an unresolved case in which a suspected murder leaves neither a confirmed corpse nor a reliable account of what happened. The colonel’s disappearance links his tale of a Templar treasure to a missing briefcase, a possible associate in Vladimir Rakosky, and a police investigation whose competing explanations never settle into certainty. Years later, an episode at the Picatrix offices brings the case back into view, when a medium repeats details Casaubon remembers from Ardenti’s story.

The Appointment and the Call

The immediate chain of events begins at Garamond Press, where Jacopo Belbo receives a telephone call after Ardenti’s visit. The caller is a police inspector, and Belbo reports that the colonel had come the previous afternoon to offer him a book. He initially describes the subject as a largely fabricated story about a supposed Templar treasure, but when he learns that the police are asking about a possible death, he tells them that Casaubon, another consultant, was present at the meeting. The call turns a doubtful publishing encounter into a police matter before Belbo or Casaubon knows what has happened.

Belbo explains that Ardenti had claimed to have found documents in France containing evidence of a treasure. The colonel spoke as if he possessed a dangerous secret and wanted to make it public so that he would not be the only person who knew it; he also said that earlier discoverers had mysteriously disappeared. He would show the documents only if he first received a publishing contract, while Belbo would not promise a contract without seeing the material. They had agreed vaguely to meet again. Ardenti had also mentioned an appointment with Rakosky, whom he described as an editor, and said that Rakosky had advised him to delay publication. He had not told Rakosky about his appointment at Garamond.

The Hotel Room and the Missing Body

At the apartment hotel, Inspector De Angelis tells Belbo and Casaubon that Ardenti had checked in four days earlier under the name Colonel Ardenti. The establishment has only one desk clerk, who goes to bed at eleven; guests can enter with a key, and the porter is an unreliable witness. The clerk says that Ardenti returned at about ten the previous night with two men who sounded foreign. At around ten-thirty, Ardenti requested whiskey, mineral water, and three glasses. Later, the porter heard erratic ringing from room 27 and entered with a passkey when no one answered.

The porter said that the room was in disorder and Ardenti was lying on the bed with wire around his neck. He and the clerk fled rather than remain in the room. They tried to use the telephone, which seemed out of order, then went for help separately: the clerk used a public pay phone, while the porter went to a doctor’s house. After roughly twenty minutes, the doctor and police arrived. The room was still disturbed, but the bed was empty. There was no corpse.

The absence of a body makes the witnesses’ account impossible to confirm. The two visitors might have stayed until the porter entered, escaped with Ardenti’s body during the interval when the hotel staff were away, or left earlier without being noticed. An outside staircase led to a courtyard and then to a side street. De Angelis also considers whether the porter, who had been drinking and was known to see things that were not there, had imagined the corpse. The clerk cited an earlier false report by the porter as a reason to distrust him. De Angelis states that the room had been searched and that Ardenti was missing; he cannot establish whether the colonel had been killed, had left voluntarily, or had ever lain dead on the bed.

Rakosky and the Briefcase

A slip of paper found near a small table records two appointments: Rakosky at the Hotel Principe e Savoia at two o’clock, and Dr. Belbo at Garamond at four. The police identify a Vladimir Rakosky registered at the hotel with a French passport, matching the description given by the hotel clerk. His name appears on the passenger list for the first flight to Paris that morning, and the police have alerted Interpol. This gives the investigation a possible link between the earlier meeting and the night Ardenti vanished, but it does not establish what Rakosky did or whether he was one of the two men who came to the room.

The room contains Ardenti’s jacket and passport, as well as a substantial amount of money. The money makes robbery an unlikely explanation for what the visitors sought, while the jacket’s presence complicates the possibility that Ardenti simply left: the porter had said the man on the bed wore a jacket, but De Angelis allows that it may have been a different one. The missing object of greatest interest is the briefcase in which Belbo remembers Ardenti carrying his papers. Casaubon recalls it as reddish; Belbo calls it brown and admits he may be mistaken. De Angelis concludes that it is gone and suspects the visitors took it.

De Angelis doubts that Ardenti was chiefly seeking a publishing contract. He proposes that Ardenti may have possessed material with which to blackmail Rakosky and used the book proposal as leverage. But the inspector’s alternatives remain speculative: perhaps the visitors threatened Ardenti and he fled with the briefcase, after trying to make the porter believe he was dead; perhaps they killed him and removed both briefcase and corpse. Neither hypothesis explains every detail of the disturbed room. The investigation produces possibilities, not a verified sequence of events.

The Case Returns

The case resurfaces about a year after Ardenti’s disappearance, when police happen upon information that someone had seen him leaving the Picatrix offices with a young medium. Much later, Casaubon attends a performance in which a woman enters a trance and speaks of a temple, a door, a vortex of power, six seals, a long wait, and thirty-six invisible figures. The references remind him of Ardenti’s account. As he tries to approach the woman afterward, De Angelis stops him and explains that the police know where to find her; she had come to their attention through the older investigation.

De Angelis questions Casaubon about why he remembers the séance’s reference to six seals so clearly when he had described Ardenti’s story to police only in general terms. Casaubon explains that Ardenti had mentioned six seals protecting the treasure, but he had not considered the detail important at the time. The exchange exposes a gap between what Casaubon once chose to report and what he later recognizes as significant. It does not resolve the disappearance: the medium’s words revive the colonel’s story but do not prove that its claims were true, explain the missing briefcase, or establish what happened in room 27.

Narrative Function and Uncertainty

The case is presented through a sequence of partial accounts: Belbo’s recollection of a publishing meeting, the hotel staff’s uncertain testimony, the physical traces left in the room, and De Angelis’s provisional reconstruction. Each adds a fact while leaving a crucial absence in place. The alleged body vanishes before the doctor and police arrive; the briefcase disappears; the two visitors’ identities and actions remain unverified. Even the detail that might seem most decisive—the appearance of a corpse—is filtered through a porter whose reliability is in question.

That structure makes Ardenti’s disappearance an early example of the novel’s movement between historical claims, suspicion, and interpretation. His story offers a secret whose supposed discoverers vanish, and then the man telling it vanishes in circumstances that seem to repeat the pattern. Yet the resemblance cannot serve as proof. The police can document the appointments, the room, the missing papers, and Rakosky’s departure for Paris, but the evidence supports no final answer about Ardenti’s fate. The later recurrence of the six seals deepens the mystery without closing it.
