Final answer:
The governess suspects Flora is trying to deceive her because of Flora's behavior and refusal to acknowledge the supernatural occurrences.
Step-by-step explanation:
The governess suspects Flora of trying to deceive her in the novel 'The Turn of the Screw' by Henry James. The governess believes that Flora pretends to be innocent and naïve in order to hide her involvement with the supernatural occurrences and the malevolent influence of the ghosts she sees.
The governess's suspicion is fueled by Flora's behavior, such as her secretive interactions with the ghosts and her refusal to acknowledge their presence when the governess confronts her.
