Just finished. Loved loved loved it. I could have read on for another 900 pages.
Thoughts:
I loved how much character growth Strike has gone through since IBH, he's become someone worthy of Robin now and he's starting to realise it. Declaration at the end was perfect. I was afraid he would take Robin's non-response as another 'look of horror outside the Ritz', but his quietly confident "We'll see" to Pat shows that he didn't. Delicious.
Rowena Ellis really needed an online footprint, that struck me straight away. There's no way the UHC wouldn't have researched all their recruits - especially the potentially lucrative ones - before taking them to the farm.
I was sure Daiyu was still alive and would turn out to be someone we had met as an adult character, although not Becca - even in an environment with no calendars and where birthdays weren't celebrated, you couldn't bring a 7-year-old away for 3 years, then bring them back and tell everyone they were 14. And even with all the brainwashing in the world, people would have known who she was.
So the jogger on the beach was... not related to anything? There was so much focus on him/her on the noticeboard in the office, it was mentioned over and over again, but no resolution there (unless I missed something?).
Charlotte's suicide was - unfortunately - very realistic for her character and I thought
Strike's mixed reaction of sadness and relief was completely believable. And his relative lack of guilt was appropriate too. Yes, perhaps if he'd called her back that night she wouldn't have done it, but it would just have happened again and again until eventually she went through with it. He couldn't continue that pattern forever.
I really love Lucy. She's come through a truly awful, traumatic childhood and has given everything she has to not allowing the mistakes of her mother to carry through to the next generation. I'm glad Strike is starting to realise that and to treat her as more than just an obligation.
Please stop the phonetic rendering of working class and regional accents! It's not necessary and makes those passages so hard to read. It's possible to convey the same impression of dialect through word choice and syntax without messing with the spelling.
