What is the main conflict in The Public Image by Muriel Spark?

Annabel Christopher has just moved to Rome with her husband Frederick and her baby Carl. Prior to her relocation to Rome, Annabel was an unremarkable British actress for about ten years, but in the two years leading to her move to Italy, her acting career took off. Her film success began with a film entitled The House on the Piazza in which she was portrayed as an "English Tiger-Lady." Since this initial success, her public image has become that of the English Tiger-Lady. In accordance with this public image, Annabel leads a reserved public life with her devoted husband while she presumably enjoys a passionate sex life with him in private.
