Looks at the police (well, European and US domestic police) and how they are situated in the titular fabric of social order, as well as what "social order" is and where our current obsession with it comes from (spoiler alert: it's liberalism). There are a number of interesting reformulations Neocleous proposes in this book when he examines the social and political role of the police, the police state, and the welfare state (Neocleous says the delineation between the police state and the welfare state has meandered pretty freely over the past 200 years or so, which is a good thing for any abolitionist to think on imo.)
One thing Neocleous does a lot of, which temporarily bumped my review on this book up from 4 stars to 5, is examine the words we use to talk about police, their etymologies, how they are shaped in other languages, etc. I am personally really tickled by etymology and many other readers are too, so you might like that. (For example, "police" were invented to enforce "policy"; "propriety" describes the way diligent members of the bourgeoisie act re: "property" - little things like that.)
However, one star has been deducted again after acknowledging this delight, to bring the book back down to a 4, because only domestic policing within Europe and the US is discussed basically at all. And even there we primarily just see discussion based in the UK specifically as well as the US. I think it would be really, really challenging to lay out as clear of a vibe check on other cultures' ways of instilling social order too, especially in a book which was short enough for a layperson to deal with, so I don't fault Neocleous on that. But it would be cool for abolitionist discourse to have more of that and sadly this book ain't where to find it.
