"The originals of these transcripts," said the courier, "are in the hands of the Marchese d'Agdolo, let him be arrested, and a comparison of the documents made."
The Privy Council was at once assembled, and the papers received from Frederick II. were laid before it. The members voted unanimously that the Marquis should be arrested, and General Schiebell was entrusted with the execution of the decree. No surprise was occasioned by the entry of General Schiebell into the house of Ferber. It was a place of resort of the best society in Dresden; but when the General announced that he had come to make an arrest, many cheeks lost their colour.
"In the name of his Serene Highness the Elector," said the General, "I make this man my prisoner," and he laid his hand on the shoulder of Agdolo, who had served under him in the Seven Years' War. He was taken at once to his own lodgings, where his desks and boxes—already packed for departure—were opened, and all his papers removed. The same night, under a strong guard, he was transported at 10 o'clock, to Königstein. In that strong fortress and state prison, perched on an isolated limestone crag, the rest of his life was to be spent in confinement.
But the Marchese, like a crafty Italian, had made his preparations against something of the sort; for among his papers was found a communication addressed by him to the Elector, revealing the whole plot. It was undated. If the search of his rooms and the discovery of his papers had been made earlier, the Elector might have believed that the man had really intended to betray his mistress, but, he had postponed the delivery of the communication too late.[17]
A few days later, the Marchese received a sealed letter from the Elector; and he was treated in his prison without undue severity; his pension was not withdrawn; and the Elector seems never to have quite made up his mind whether Agdolo really intended to make him aware of the plot at the last minute, or to go on with the plan after his mistress's orders.
After some years, when Agdolo began to suffer in his chest, he was allowed to go to the baths of Pirna, under a guard. His wife never visited him in prison. She died, however, only two years later, in 1778, at the age of fifty-six. Agdolo lived on for twenty-three years and a half, and died August 27, 1800. All his papers were then sent to Frederick Augustus III., who read them, dissolved into tears, and burnt them.
We must return for a moment to Munich. No sooner had the emissary of the Electress Mother heard of the news of the arrest of Agdolo, than he hastened to Munich with post horses as hard as he could fly over the roads. Maria Antonia, when she heard the news, at once made fresh dispositions. She sent word that same night to Hewald to make off, and in another half hour he had disappeared with the diamonds.
Next day the completion of the resignation of claims was to be made. The Electress Mother requested the Treasurer Zehmen to go to the dwelling of her Councillor Hewald, who, as we can understand, was not to be found anywhere. Herr von Zehmen was much surprised and disconcerted, and the Dowager Electress affected extreme indignation and distress, charging her plenipotentiary with having robbed her of her diamonds, and bolted with them. Then she took to her bed, and pretended to be dangerously ill. Next day the news reached Zehmen of what had occurred at Dresden, and with the news came his recall. She saw the treasurer before his departure, and implored him to get both Agdolo and Hewald arrested and punished, because, as she declared, they had between them fabricated a wicked plot for her robbery and ruin.
Hewald went to Frankfort with the jewels, where he was stopped and taken by an officer of Frederick Augustus, and brought on Jan. 27, 1777, to Dresden. He was sent to the Königstein, but was released in 1778.
