Pretty good mystery, but not as good as the previous 3 books. Robin's & Matthew's relationship stuff & Strike's & his gf's relationship stuff got pretty tiresome, and took up way too much space that could have been told us about Strike's office being gentrified out of its building. The mystery was pretty fun, and I liked all of the ridiculous and seedy aristocrats. I felt like the impacts of the London Olympics on the neighborhoods they were sited in could have been explored more. The next book will almost certainly have lots of dancing around Strike & Robin's relationship, but at least it won't have Matthew, so I'll be reading it.
