Jane Casey has written up to this point. First of all, The Kill, the 5th book in the series, will not be published in the US until June 2nd. It is already available in the UK and somehow the audio is also available at this time. I'll try to be careful about spoilers, but just saying...
I loved this book. And I listened to it and liked the narrator, Sarah Coomes, fairly well. Her male voices were a tiny bit wonky, but not too much and I could not wait until June. So, a listen it was.
The book begins with our characters outside of London attending a wedding of a colleague. Everyone is there, but some are still technically on duty, so having to abstain from the alcohol. And it's a good thing as they get a call to return to the city ASAP. A policeman has been shot on his way home from his shift. The murder site is a park and the witnesses were badger watching (is that really a thing?). Maeve leaves her boyfriend, Rob, behind at the wedding and travels with DI Josh Derwent to begin the investigation. Since the victim is a police officer, everyone is being especially careful and diligent. When they inform the officer's family of his death, the wife and daughter seem a bit off. Cold and uncooperative would be their reactions.
As Superintendent Godley's team is primary on this case, everyone is putting in the hours. And then it happens again. This time several police officers are down. Everyone is in a panic and the media descends with hard questions. Pressure abounds from the upper echelon of police administration and other government types. Who is doing this? How are these crimes connected? Is any police officer safe? The answer is no. Superintendent Godley doesn't seem himself and Maeve can't help but remember a secret that she knows about him. Should she confront him or tell Derwent? And Maeve's own home life with Rob becomes incredibly complicated all of a sudden.
We get to see more about all of our favorite characters, Maeve and Rob, Derwent, and also Godley. Different facets of each of their characters are revealed. Meanwhile, someone is running around London killing members of the police and getting away with it. Trust me, you don't want to miss reading this one. Some issues from previous books are resolved and, of course, more arise. And may I just say, I can't stand Godley's second in command, DCI Una Burt. Cannot. Stand. Her. That's all I'll reveal, but sheesh....what an awful woman.
I understand that the next book in this series will be published in the UK this summer. I might have to order it. If you've not read this series, it begins with The Burning. Highly recommended.
