I'm not much of a sleuth. I'm an old lady, a former English teacher and voracious reader of all kinds of novels and non-fiction. In Marion's story, I hear a narrative and hear characters, as if the story were being composed by an overarching being. For me, the story of Marion is about a romantic, vulnerable woman. Her lifelong career is no longer satisfying. Her children are grown. She's alone. Until she falls in love, with a man she believes is the real deal. He proposes to go along on the romantic trip to England Marion has always dreamed of. The plan, as he tells Marion, 1. is a secret trip to England where they will marry; 2. where they would retrieve Marion's money and then-- 3. move to Luxembourg to start her new married life. All very innocent and easy for a romantic woman to believe. You can imagine Marion in England holding her secret and planning to spring it on her loved ones. "I'm married! I'm moving to Europe! It's all good! Come visit!"
Instead, the man cancels the lifetime goal of the Orient Express. Tells Marion she's ruined everything.
In the novel playing in my head, Marion returns to Australia, crestfallen or maybe shaken. The marriage didn't happen in England. She tried to withdraw her England money and couldn't with the new name. The man loses his temper because she changed her name in advance. He says they must return to Australia. Marion imagines a short visit, a detour to her marriage. Perhaps she's even a bit suspicious but guilty too. She does what her fiance proposes and withdraws the bank money in preparation for the big move, waiting for his approval to contact Sally and Owen. Which never happens. . . .
The man gets what he wants. Marion is expendable. Or ashamed, Marion hurts herself. I don't believe Marion was a schemer, or a deserting mother. I don't believe she was a fool or was hurtful. I believe she is like most woman I know. A romantic whose heart led her astray. Novels (and my own life) are full of this narrative. The man who promises and then hurts. The woman who gets caught in a trap and can find no way out.
Delusion is powerful when we want to believe what we want to believe.
