In essence, Derailed is the story of an affair gone wrong. A rather average husband and father, Charles meets Lucinda on the train and is sucked into a torid affair. Yet when they finally venture to a hotel room, a man follows them, beats Charles up, robs them, and rapes Lucinda. In the aftermath, Charles is blackmailed, a man is killed, and his family is threatened. Yet was Lucinda who she really claimed to be?
If I had to select one word to describe this novel, it would be contrived. Or implausible. The plot was too far-fetched and I was unable to suspend my disbelief. I was further irritated by the complete lack of characterization of every character besides Charles. Every character is one thing - Lucinda is sex, Deanna is devoted, his daughter Anna is ill. It was disappointing. Charles, himself lacks character development for the most part. But of what I do know about him, I don't believe this tale would happen to him. He's too sensible, too loyal, too average. He would have called the police. He would not create a new identity. Also - that bomb would not have gone off. I sort of felt as though Charles was recounting a dream to the reader, in which he is suffering from severe delusions of grandeur.
I haven't seen the movie based on this novel, nor do I want to after reading this. And I can't figure out why they wanted to make this into a movie. Even the great plot twist is just not that twist-y.
I will say I was impressed by the frame story of this novel, which begins after the main story has concluded. Charles is teaching english to inmates and one begins writing a third person narration of a story of a man on a train. But it's Charles' story. Someone from his past is threatening him by feeding him his own bio. And eventually he takes over and begins to tell his own story in first person. It was a really interesting and unusual introduction and I applaud the originality.
