How will terminate the career of that brilliant King of Sweden, who had received from Versailles and from Paris, from the court and from the city, such an enthusiastic reception? Gustavus, the idol of the great lords, the philosophers, and the fashionable beauties, who, after being the hero of the encyclopædists, came to hold his court at Aix-la-Chapelle amid the French émigrés, and who, on his return to Stockholm, prepared there the great crusade for authority, announcing himself as the avenger of divine right, the saviour of all thrones? The last days of his life, his presentiments, which recall those of Cæsar, his superstitions, his belief in prophecies, his magic incantations, that warning which he scorns, as the Duke de Guise did at the castle of Blois, that masked ball where the costumes, the music, the flowers, the lights, offer a painfully strange contrast to the horror of the attack; all is sinister, lugubrious, in these fantastic and fatal scenes which have already tempted more than one dramatist, more than one musician, and whose phases a Shakespeare only could retrace. The crime of Stockholm is linked closely to the death-struggle of French royalty. The funeral knell which tolled at this extremity of the North had echoes in Paris. The Swedish regicides set the example to the regicides of France.

M. Geffroy has remarked very justly in his work, Gustave III. et la cour de France, that the bloody deed which put an end to the reign and the life of Gustavus is not an isolated fact: "The faults committed by this Prince would not have sufficed to arm his assassins. The true source whence Ankarstroem and his accomplices drew their first inspiration was that vertigo caused during the last years of the century by the annihilation of all religious and even all philosophical faith.... No moment of modern history has presented an intellectual and moral anarchy comparable to that which accompanied the revolutionary period in Europe."

The eighteenth century was punished for incredulity by superstition. Having refused to believe the most holy truths, it lent credence to the most fantastic chimeras. For priests it substituted sorcerers; for Christian ceremonies, the rites of freemasonry. The time was coming when, because it had rejected the Sacred Heart of Jesus, it was going to bow before the sacred heart of Marat. The adepts of Mesmer and of De Puysegur, the seekers after the philosopher's stone, the Nicolaites of Berlin, the illuminati of Bavaria, enlarged the boundaries of human credulity, and the men who succumbed in the most naïve and foolish manner to these wretched weaknesses of mind, were precisely the haughtiest philosophers, those who had prided themselves the most on their distinction as free-thinkers. Such a one was Gustavus III.

This Voltairean Prince, who had held the Christian verities so cheap, was superstitious even to puerility. He did not believe in the Gospels, but he believed in books of magic. In a corner of his palace he had arranged a cupboard with a censer and a pair of candlesticks, before which he performed cabalistic operations in nothing but his shirt. Throughout his entire reign he consulted a fortune-teller named Madame Arfwedsson, who read the future for him in coffee-grounds. Around his neck he wore a gold box containing a sachet in which there was a powder that, according to his belief, would drive away evil spirits. All this apparatus of incantation and sorcery was one of the causes of Gustavus's fall. It multiplied the snares around the unfortunate monarch, and served to mask his enemies. Prophecies announced his approaching end, and conspirators took care to fulfil the prophecies.

The Duke of Sudermania, the King's brother, without being an accomplice in the project of crime, encouraged underhand practices. Sectarians approached Gustavus to reproach him for his luxury, his prodigalities, his entertainments, or addressed him anonymous warnings which, in Biblical language, declared him accursed and rejected by the Lord. Their insolence knew no bounds. Madame Arfwedsson had counselled the King to beware if he should meet a man dressed in red. Count de Ribbing, one of the future conspirators, having heard of this, ordered a red costume out of bravado, and presented himself in it before his sovereign, whom such an apparition caused to reflect if not to tremble.

Gustavus, like Cæsar, was to see his Ides of March. It had been predicted to him that the month of March would be fatal to him. This month approached, and the monarch diverted himself by fêtes and boisterous entertainments in order to banish the presentiments which never ceased to assail him. He said to himself that all this phantasmagoria would probably soon vanish; that the funereal images would of themselves depart; and that the spectres would disappear at the sound of arms. The monarchical crusade of which he proposed to be the leader grew upon him as the best means by which to escape the incessant obsessions haunting his spirit. In vain was he reminded that Sweden was in need of money, and that a war of intervention in the affairs of France was not popular. His resolution remained unshaken. He counted the days and hours which still separated him from the moment of action: his sole idea was to chastise the Jacobins and avenge the majesty of thrones.

Returned to Stockholm from Aix-la-Chapelle, at the beginning of August, 1791, the impetuous monarch began to be very active in his warlike preparations. The Marquis de Bouillé, who had been obliged to quit France at the time of the unsuccessful journey to Varennes, had entered his service and was to counsel him and fight at his side under the Swedish flag. At the same time Gustavus officially renewed his promises of aid to the King of France. Louis XVI. replied:—

"MONSIEUR MY BROTHER AND COUSIN: I have just received the lines with which you have honored me on the occasion of your return. It is always a great consolation to have such proofs of a friendly sentiment as are given me by this letter. The concern, Sire, which you take in all that relates to my interest touches me more and more, and I recognize in each word the august soul of a king whom the world admires as much for his magnanimous heart as for his wisdom."

Meanwhile the conspirators, animated either by personal rancor or the passions common to nobles hostile to their king, were secretly preparing for an attack. The five leaders were Captain Ankarstroem, Count de Ribbing, Count de Horn, Count de Lilienhorn, major of the Blue Guards, and Baron Pechlin, an old man of seventy-two, who had been distinguished in the civil wars, and was the soul of the plot. The conspirators had doubts before committing the crime. During the Diet, which met at Gefle, January 25, 1792, they refrained at the very moment when they were about to strike.

Gustavus was in his castle of Haga, about a league from Stockholm, without guards or attendants. Three of the conspirators approached the castle at five in the evening. They were armed with carbines, and, having placed themselves in ambush near the King's apartment on the ground-floor, were awaiting an opportunity to kill their sovereign. Gustavus coming in from a long walk, went in his dressing-gown to sit in the library, the windows of which opened like doors into the garden. He fell asleep in his armchair. Whether they were alarmed by the sound of footsteps, or whether the contrast between the slumber of the unsuspicious King and the death poising above his head awakened some remorse, the assassins once more abandoned their meditated crime.
