Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
If you like a book where England still has a class system, men inhabit men's clubs and involves a group of caricature authors in a seaside setting and great swads of description and every so often a word of the day. Then you might like this book. It never seemed to engage me. It is fortunate that the murderer (who is easy to pick) confesses everything at the end as the murder method is fanciful and unbelievable. Adam stands at the edge of this mystery and behave like he has autism to some degree. PD doesn't seem to make the relationships believable or sympathetic. For the Fans.
