It was only after she saw what was happening that she heard two screams from the boy, although her attention was totally focused on reciting the car's registration to herself over and over again, so she could give it to the police.
"I was just in the right place at the right time," she said, adding that she had had the presence of mind not to put her head out the window, in case the kidnapper saw her and realised that there was a witness.
She didn't recall a great deal else, although she told police that she would have recognised the kidnapper, and would be prepared to give evidence against him via audio-visual link. The offender was duly arrested, but he pleaded guilty, and Marie's evidence wasn't needed.
To this day she didn't know what had motivated the abduction, or what happened to the offender.
Marie was in Australia for around 18 months, helping her brother Brian with his trailer home business, but now she's back home at Waiharara, well and truly earning her keep in parents Vern and Rosie Ireland's dairy farm, and still writing. She was working on a screenplay, which has attracted praise in Hollywood, while she was in Australia, and is now turning it into a novel.
It was a fantasy adventure story, she said, with a strong spiritual element, aimed at helping young readers understand themselves and find purpose in life, as well as showing parents how they can help rather than harm their children.
She still plans to find a way of making the film one day, but in the meantime hopes to follow brother Brian, who has just released a sci-fi novel depicting the end of the world, as a published author.
Any kidnapping scenes should be thoroughly convincing.
