Wow - I was not expecting to be one of only a small handful of people on this thread not to have loved the book :-s
I love the Strike series more than anyone I know - people online excluded ;-) - and I never used to see why some reviewers said that JKR’s books needed tighter writing or heavier editing. For me, the language flew so readably, and the descriptions were just right.
But about a third of the way through this book, I started thinking it was getting a bit tedious. And by the time Strike and Robin were on Sark and one of them noted that the pub’s lavatory doors read “Gentlemen/Hommes” and “Ladies/Femmes” I had a sinking feeling. Oh, and the toilets were across a yard. And the carpet in the bar was red. I mean, WHY! In a book 900 pages long, that is just ridiculous and unnecessary detail. How could any editor not have cut that?! I mean, it’s very satisfying for any Strike pilgrims that follow in JKR’s footsteps and note that yes indeed, that is what is written on the toilet doors - but for literally ANYONE else it’s just tedious minutiae!
And don’t get me started on the storm that meant they might have to spend another night on Sark, whoops, oh no it’s actually fine, just a two hour delay… what was the point of that!
I am still a massive fan and cannot wait for book 9. But this is perhaps the first book written by JKR where I have honestly (ever!) thought the writing quality was not 100% gold.
NB I have found this thread illuminating and after reading more about PTSD here I am less annoyed at Robin. And I totally got HP OOTP vibes as a previous poster mentioned - even while reading the book I was thinking that perhaps this misery is necessary for future payoff… And I loved the Rokeby chapter, and thought Strike needing a DNA test himself might help him forgive Rokeby… but I still think it needs a pair of garden shears taken to certain chapters!
