Concurrently, the Clement Affair took place, in which the alleged Hungarian nobleman Clement gained access to the king by use of false letters and convinced him that the courts of Vienna and Dresdena were orchestrating a plot to depose him in favor of the crown prince who, under the guardianship of the Emperor, the queen, Grumbkow, and Arnhalt, was to then be raised a Catholic. All were accused of having been implicated in the plot before Clement was exposed as a con artist and summarily executed; another implicated was M. de Troschke, a gentleman of the chamber in service to the king, in whose possession was found a letter from Madame de Blaspiel expressing anger at the king's imprisonment of a suspected accomplice, Monsieur de Kamecke. Grumbkow, suspecting the queen's favorite to have exposed his plot against the queen, delivered the letter to the king, who had de Blaspiel arrested, imprisoned for a year at Spandau, and then banished. Her arrest forced the queen to remove the will of 1719 from the possession of Blaspiel before it was discovered there, to which end her chaplain procured it from the officer commissioned to seal up de Blaspiel's room. After this the queen replaced her as confidant with her daughter, Princess Wilhelmine.
