What is the theme in The Public Image by Muriel Spark?

As the title of this novel suggests, Annabel's public image is one of the important subjects of this book. Annabel's career is founded on her public image as the English Lady-Tiger. Her first major film success, The House on the Piazza, was promoted by appealing to her image as the English Lady-Tiger. Subsequently, this public image was cultivated further due to the efforts of Luigi Leopardi's press secretary, Francesca.
