This was better than the last book. Primarily because it was set in London and was centered around the Faceless Man.
But there were still some irritating things. First, the complete absence of direct address commas. Where have they all gone, editors? Second, references to events that occurred in the graphic novels. Aaronovitch has spent a lot of time and creative energy on them, I get it, but they are a completely different media that not everyone enjoys, and it is irritating as hell to see something, and making a reference to them as canon is a way to alienate some readers. Third, a lot of the characters and events of this book felt like they’d retconned by Aaronovitch to me in some ways. Tyburn suddenly likes Peter on a personal level? And other stuff that would be serious spoilers. But some of it felt really inconsistent with the world as previously established. Unless, of course, Peter as narrator is even more unreliable that I thought.
