Giacomo Casanova and sister Maria Maddalena were living. His new play, "La Moluccheide", now lost, was performed at the Royal Theatre, where his mother often played in lead roles. He then visited Prague and Vienna, where the tighter moral atmosphere of the latter city was not to his liking. He finally returned to Venice in 1753. In Venice, Casanova resumed his escapades, picking up many enemies and gaining the greater attention of the Venetian inquisitors. His police record became a lengthening list of reported blasphemies, seductions, fights, and public controversy. A state spy, Giovanni Manucci, was employed to draw out Casanova's knowledge
Giacomo Casanova but could not sustain it. He ran the business poorly, borrowed heavily trying to save it, and spent much of his wealth on constant liaisons with his female workers who were his "harem". For his debts, Casanova was imprisoned again, this time at For-l'Évêque, but was liberated four days afterwards, upon the insistence of the Marquise d'Urfé. Unfortunately, though he was released, his patron de Bernis was dismissed by Louis XV at that time and Casanova's enemies closed in on him. He sold the rest of his belongings and secured another mission to Holland to distance himself from his troubles.
