My first rating, 4.5 stars. Although I'm not good at handling any kind of numerical evaluation system (which is unfortunately clearly necessary).
A rare thriller on Central Asian geopolitics. Lots of proper names make it at least seemingly well-researched, which worked pretty well on me. And it's a traditional one point of view story centered on solving a mystery, not a multi-POVs (or at least, two) from all sides story I'm used to as in most techno-thrillers, which is understandable since the author wrote detective stories. It would be on my top ten if I was good at ranking, which I'm not. But there are some holes in the geopolitical plot depicted.
The plot is presumably proposed to the British government but was deemed too aggressive. A private sector mogul picked it up, bought a oil company, and assembled a list consists of a public relations company and some private security contractors to make it happen: pretend to find a new mega oilfield in Kazakhstan, then stir things up in the country using a mix of information warfare, including an enhanced version of deep fake that seems omnipotent, and false-flag operations, climaxed by assembling a Islamic terrorist organization using links provided by ex-SIS (sorry I always prefer this appellation to MI6) intelligence officers, instruct it to strike in Russia to arouse Russians' hatred to it and give them a justification for later actions, then strike two blows in Kazakhstan, in one of which claims its president Nazarbayev (should I feel surprised that the real name is used?), to seduce (in the information operations, they use bloggers to publish pro-Russia materials, this could be interpreted as making the Russians believe they could use it as an advantage) the Russians into install a pro-Russia leader and even invading the country to put Russia into a more intensified geopolitical conflict with its ally, China, and hopefully distract them from Middle East.
But could the discovery of an oil field, with all its facilities installed, be faked? I don't know the cost, but I tend to answer "no".
And in fact, there are unnecessary maneuvers. For example, the pro-Russia information campaign could be removed and still instigate a strong Russian response if Kremlin wants one. An Islamic terrorist insurgency is enough. And it is never clarified that whether a faked proactive annexation by Russia is intended to boost Russophobic sentiment in the West. So it could well be a subterfuge just to bewilder the readers. Understandable and as I explained above, fortunately logical.
And then comes the faked video of the protagonist (which is to frame the UK of supporting the Islamists) and later the revelation of protagonist's identity as an SIS officer by the information campaign. What does these mean? To deliberately sabotage the UK-Russia relations? Or maybe there are further considerations to manipulate British internal politics that is unspecified in the story? So, this is too abrupt a plot device to draw the protagonist into the investigation.
The logic chain of Hugh Stevenson's sudden murder and Stefan's fate was not clearly explained, which was in accordance with the fog of war of first person narrative, but left me disappointed.
There are other questions, maybe because I didn't read attentively enough or I'm not clever enough. The true nature of Moscow's Chief Ideologue on Expansionism Vladislav Vishinsky (I thought there's only Vyshinsky though, there's an и/ы distinction) is also interesting. It is hard for me to determine whether he's really a British agent, although I prefer not. Maybe it's in protagonist's disinformation that he's a British agent, although one of Vishinsky's people truly had taken Joanna a ride and he himself had said something mysterious more than ten years ago in a strange encounter with the protagonist in Baku, and I'm not so happy about his supposed final abduction. It's too easy if it was caused by a piece of disinformation, in contrast to the strong main part.
Finally, in the end, after the protagonist's name and face gone viral everywhere on the Internet, he dared to travel freely instead of subject to an official escort. So maybe he was good at makeup then?
