I recently took a train in the UK, the first time for several years, seeing I don't live there. There was an exceedingly irritating security announcement in all the stations and trains every few minutes ending in "See it. Say it. Sorted". Apparently it irritated Jonathan Coe as well (to be honest, I can't imagine anyone not being irritated by it) as it is a recurring theme throughout the book.  He manages to turn the irritation into humour, and indeed the whole book is immensely funny, as we have been led to expect from him. There are, of course, the inevitable references to lettuces (the book is set in the brief period of Liz Truss' prime ministership), but that is not overdone. 
A particularly enjoyable aspect is that he also has fun with the cosy mystery genre, and indeed pokes fun at the literally world as a whole.  I enjoyed the horror of the professional writer at discovering that they were talking to someone writing a novel and the thought that they might start to tell them all about it. He also has some interesting side comments on the process of writing, like a discussion on writing in the present or past tense (or was that meant humorously as well)? He even pokes fun at himself, giving himself a cameo part as a student at Cambridge.
The book is very political. Liz Truss' disastrous term of office is the backdrop and he does an excellent job of exposing the right wing of the Conservative party as being completely out of touch with reality and hungry for power. Of course, he does that in an amusing way too.
There is a lot to like about this book. The only thing I was less enthusiastic about was that I didn't feel he had quite mastered the cosy mystery genre. That's fine though, it means he was more himself, and we could not ask for better than that.
