Oh dear. What do I say? I read this because I love David McCallum. I do not love thrillers. I do not love this kind of literature, which seems like the book equivalent of soap operas and reality shows. So, I was out of my element reading this. This will be a bitty, stream of consciousness review.
It's probably a good enough book in its genre. I am a book snob. I don't read this genre because I don't enjoy it, it doesn't grip me, there's nothing to make me want to stay the course. I listened to the audiobook, and it took me months to drag myself through, taking breaks frequently. It was a little odd because David McCallum, reading, sounded like my grandpa, but he was swearing, describing sex scenes, and all sorts of things I can't imagine my grandpa ever speaking about.
He's a reasonable writer in the genre, I think. He'd probably get published by a pulp publisher, without the famous name and with a lot of persistence. But the story was by turns dragging, grubby, unbelievable, annoying, and sordid. At one point I started to gain a little interest, but then it waned again. The story goes back and forth and bounces between characters like a squash ball. He tries to describe contemporary British things but doesn't really seem to know about a lot of things that have changed since the 50s.
There were too many characters. I didn't care about a lot of them. I didn't feel a resonance with any of them. A lot of them were cliched. None of them were likable. Many of them were unbelievable.
The rape scene: this has been talked about in the DMcC fandom circles. What do we make of that? A female character is kidnapped, then chained to a bed by her kidnapper, stripped, and raped. During the rape, realises she enjoys it. A little later she steps into the shower and her rapist steps in beside her, stops her getting out, massages her breasts, and takes her from behind against her will. She ends up in a committed long-term relationship with him. Make of that what you will.
If he wrote a sequel I'd probably read it, god help me. That's what fandom does to you. But I won't enjoy it.
