This is an extremely detailed account of the story, very well researched and packed full of information. It never bogs down though, largely because Follain is so good at capturing people, particularly the quirks in Knox's character, the flowery prosecution and defence teams and the dignity of the Kercher family.
There are some weaknesses though. Strangely, Guede is only caught in outline in these pages. The only person found legally responsible for Meredith's death draws the least attention.
One other issue is that the wealth of contradictory evidence is never analysed. The story is told strictly chronologically and no time is spent summarising keys bits of evidence to hep the reader understand the respective view points of Prosecution and Defence. Finally, certain (on the face of it) key strands are forgotten. This may be the result of these being forgotten in the trials themselves but still, the omissions are curious. For example, early in the book, the author explains that blond hairs were found both in the victim's hand, and her vagina. Who did the hair come from and how did it get there? We don't know, because this seemingly crucial evidence is never mentioned again.
Don't read this if you want to be told who did it; the author does not give a view. But if you want an intelligent (as opposed to titilating), well researched account then this fits the bill.
