Ce mal étrange (Pocket Book)

The protagonist's descent into madness feels both realistic and unsettling. I wonder what personal or cultural influences shaped her depiction of psychological unraveling.

The slow burn leading to moments of intense suspense made me wonder if Highsmith planned the pacing from the start or let it evolve organically.

The blurred line between love and madness really kept me questioning what was real. Does anyone else think this ambiguity adds to the story's haunting quality?
