On 15 September 1816, three days after his disappearance, Franz Xaver Keller was discovered upon a spit of sand along the Reuss, some two hundred paces from the path where his family had lost sight of him. His watch had stopped at twenty-six minutes past nine. His pockets still held his money; he remained fully clothed, save for his hat, though the fabric of his breeches was worn at the knees and torn near a pocket. The autopsy noted slight contusions compatible with a fall, but no conclusive trace of violence inflicted by another hand. To the medical men, the river and a sudden fainting fit had most probably caused his demise. The river had surrendered the body; it did not reveal how he had entered the water.
Keller was the chief magistrate of Lucerne. On the evening of 12 September, following a gathering at the cantonal casino, he had quitted the town at half-past eight in company with his two daughters to walk to his country estate at Geissmatt. The short path skirted, in places, an abrupt and precipitous bank. That night, rain lashed the slopes, the wind drowned out their voices, and the swollen Reuss rushed past with a deafening roar. The young women walked beneath umbrellas, one ahead of her father, the other behind; in the pitch darkness, they became separated. As they drew near a perilous turn, Keller called out to his younger daughter, bidding her keep to the safe side of the path. Thereafter, his voice was swallowed by the storm.
Come morning, when it was discovered that he had not arrived at Geissmatt, the first instinct was to search for him. A neighbour, Joseph Pfyffer von Heidegg, hastened between the manor and the town, questioned relatives, and alerted the authorities. The search parties combed the banks until the current cast up the corpse. Nothing in the examination, as recorded in the Pitaval, compelled the opening of a criminal inquest. The halted watch, the spells of vertigo from which Keller was said to suffer, and the proximity of the torrent offered an explanation simple enough; the post-mortem revealed no wound indicative of an assault. A venerated magistrate was laid in the earth, and the affair was deemed an unfortunate accident and closed.
Death, however, did not extinguish the fires of politics. Keller belonged to the faction styled in the chronicle as “Freisinnig,” opposed to the Ultramontane circles allied with the papal nunciature. The compiler of the Pitaval depicts both camps as locked in a bitter struggle for power, betraying his own pronounced sympathies against Keller’s adversaries. He records that certain townsfolk had immediately whispered of suicide, others of foul play, and that the magistracy had instructed local officers to keep watch over such rumours. These pages must be read for what they are: they show how an unexplained disappearance could become, years later, a screen onto which factional strife projected its suspicions; they by no means prove that any conspiracy existed.
The woman destined to reopen the case was neither a magistrate, nor an eyewitness to that final journey, nor indeed present in Lucerne in 1816. Klara Wendel was then but a child of twelve. In 1824, at the age of twenty, she was arrested in the Canton of Schwyz for disposing of goods stolen during a burglary at Näfels, in the Canton of Glarus. At first, she maintained she had bought the wares honestly; by the following morning, her tale had shifted. She implicated her brother Johann, known as Krüsihans, before finally confessing that she had taken part in the theft by receiving the loot through an iron grating forced open by the housebreakers.
The examinations deepened. Her family belonged to the Heimatlosen—the itinerant class destitute of any recognized right of citizenship; their enforced wanderings exposed them to relentless surveillance and social stigma, which must not be mistaken for proof of criminality. Klara was acquainted with many wandering families and the refuges they frequented; she described actual burglaries with sufficient exactitude for the magistrates to verify portions of her testimony. As names and incidents poured from her lips, the authorities accorded her extraordinary attention. The chronicle portrays her through the prejudices of the era, as a vain and garrulous creature; such moralizing must not be accepted as an accurate measure of her character. What the record shows far more plainly is that her testimony was amassed over the course of twenty-eight separate examinations, governed by an inquisitorial system that relentlessly pressed her on what she had “remembered” since the previous sitting.
After several months, the supply of verifiable burglaries began to dry up. The compiler notes that the interrogators then resorted to “suitable representations”—a phrase whose sinister ambiguity he himself underscores. Klara presently began to speak of arsons and murders. Before long, she declared that a gang, led by her brother and the notorious thief Kappeler, had hurled Keller into the Reuss. Nor did she confine herself to the riverbank: in successive tellings, she swore that the men had afterwards caroused at the homes of Pfyffer and the physician Leodegar Carraggioni, who had rewarded them with purses of coin. She denounced these two patricians as the instigators of a political murder.
The tale thus concocted possessed dramatic force, yet suffered from an essential flaw: it rested upon ever-shifting declarations, extracted eight years after the event, without a single independent witness to the deed or any material relic connecting the notables to a crime. The names of the alleged accomplices varied from day to day. Klara first described a scene in broad daylight, wherein two strangers pretended to fish; later, she cast the crime into the frame of that rainy September night. At times she claimed to have heard the tale related; at others, to have overheard a secret conference; and finally, to have witnessed the murder with her own eyes from the opposite bank. In the span of eight sittings, writes the Pitaval, she altered the actors, the hours, and the very weather.
Other prisoners, broken by confinement, eventually accused themselves and corroborated the charges against Pfyffer and Carraggioni. The chorus of agreeing voices profoundly impressed the Lucerne authorities. The two gentlemen were arrested, and a local quarrel instantly assumed the proportions of an affair of state. Yet repetition was by no means corroboration: the captives were kept in overcrowded dungeons where communication could scarcely be prevented; during formal confrontations, each heard the answers given by the others. Their narratives converged within an apparatus perfectly designed to teach them what the inquisitors wished to hear.
The proceedings were subsequently transferred to an intercantonal commission, and the entire docket was moved to Zurich in late 1825. The new magistrates were charged not only with investigating the alleged assassination, but with scrutinizing the methods by which the confessions had been procured. At the first formal examination upon transfer, most of the prisoners recanted; only Klara and her sister Barbara stood by their depositions. In time, they too dismantled parts of their testimony. Klara’s own story continued to fluctuate: she withdrew the entire fabrication, only to insist intermittently that the murder had indeed occurred, while admitting that the instigation by Pfyffer had been an absolute invention. Such wavering neither permits her to be treated as a credible witness, nor elevates her final retraction to the rank of gospel truth; it compels us, rather, to scrutinize the questions that had shaped her words.
Klara’s brother, Krüsihans, stated that he had been severely beaten and threatened during his Lucerne captivity. He recounted that, after being flogged, an examiner demanded whether he knew what he had done with Kappeler in Lucerne; when he attempted to speak of an unrelated theft, he was told that they cared nothing for that, but only for Keller. The record, according to the compiler, confirmed the use of corporal punishment, a diet reduced to bread and water, and heavy irons. Magistrate Am Rhyn admitted to inflicting disciplinary chastisement, though he denied it had lasted two hours, as the prisoner alleged. The distinction is capital: certain abuses were officially documented, while others remained contested accusations.
The material heart of the mystery remained unchanged. No wound indicating an assassination had ever been found; Keller had fallen into the water, whether pushed or by misadventure. His purse and his watch were still upon his person. The route described by the accused could not be reconciled with their successive positions, nor with the route taken by Keller’s daughters. The alleged tavern rendezvous could never have occurred as related: the Pitaval affirms that the inn in question had been shut by the authorities since before 1816. Several thefts which the suspects dated to the autumn of the Schultheiss’s death were proven to have occurred the following year. Moreover, Joseph Pfyffer, branded as one of the instigators, was the very neighbour who had raised the alarm, led the search, and reported the disappearance.
These contradictions alone did not permit the reconstruction of every minute of that September night in 1816; they were, however, more than sufficient to show that the confessions could not sustain the weight placed upon them. The case against Pfyffer and Carraggioni collapsed utterly, and both gentlemen were acquitted, according to the chronicler. As for the itinerant prisoners entangled in the broader larceny trials, the final disposition of their separate indictments is not detailed with comparable clarity. It would be an error to confound those sentences with a conviction for the death of Keller. The Pitaval itself concedes that it possessed no precise record of the outcome of the patricians’ subsequent claims for damages.
A watch arrested at twenty-six minutes past nine had at first seemed to mark the moment of a misadventure. Eight years later, the words of Klara Wendel claimed to fix the hour of an assassination and name its perpetrators; under the pressure of questioning, her words bred others, graver and fraught with political venom, before unravelling entirely. The Zurich commission could not restore to Keller his final moments, which no tardy chronicle can ever retrieve with certainty. It did, however, compel justice to distinguish between an extortion of confessions and material proof, and between the idle repetition of a tale and the rigorous verification of its details. In this distinction lies the true gravity of any inquest: not in the catalogue of names wrung from the accused, but in its capacity to resist what the powerful—or the inquisitors—are so eager to hear.
