Puzzle of a Downfall Child

A beautiful but disturbed young woman lives alone at a beach cottage, reliving her past, a life of delusions and lies. Lou Andreas Sand is a former fashion model whose life has gone into a downward spiral, including drug use and a nervous breakdown. She tells an acquaintance, Aaron Reinhardt, her story for a film he is planning on her, but the details do not ring true. Lou evidently had a lover who abused her, and a penchant for sex with strange men. Along the way, she became engaged to marry Mark, an ad executive, but apparently jilted him on the day of their wedding, leading to her descent into drugs and an attempted suicide.
