Peter is now a Detective constable and they're still on the hunt for Martin Chorley, the Faceless Man, and they're getting closer to him. He has a plan that could change the future and Peter is going to need help from everywhere he can get it. What you get is what Peter sees mostly and sometimes he doesn't see anything. Bells feature and more of they mythos of London and it's all quite complicated.
Interesting to see Peter progress through his career and how things change for him and also how his relationship with Beverly changes.
I enjoyed this as always and look forward to the next instalment.
