Looks like it was first best seller from this author that made it possible for him to leave work in police and become a writer. Also, this and many other of his books were turned into movies. Which is not surprising. This Man Is Dangerous feels like that of those black and white gangster movies. And like those movies the plot and style are very simple and light. It was not boring to read, but there is not enough of plot to make your brain work, no huge twists that makes you go “oh”. There is one twist, which you start to anticipate early into reading. And when it is revealed, it is kind of expected based on a few hints dropped throughout the book and based on how main character is behaving in some situations. At the end of the book there is a tad too much of backstabbing back and forth. I guess to make it more intriguing. It was unexpected though that main action, although started in US, was actually happening in UK. Well, we author was British, but it is strange that book about American gangsters happens in Europe. The style itself is not the one i particularly enjoy. Internal monologue of the main character or from his perspective and also with lots of witty words and expressions, which just makes it feel like a cheap movie. It is for sure not some dark or serious story, nothing feels realistic. Just and entertaining, short gangster flick. 6/10
