I didn't find anything in this book - whether style or story - especially different from what you normal expect from the genre.
Like a lot of long-running series in which the same detective returns over time (as opposed to, say, Bond books, which are timeless, in the sense that Bond, M, Moneypenny etc. are always about the same age and experience little or no character development, even if the setting has been updated to suit the readership) there is starting to be a nagging aspect of the soap opera about it - hence, perhaps, the sudden emphasis on her family.
I suppose all that is OK. Many people read genre novels precisely so they don't have to face challenges in terms of form, and a lot of people really enjoy soap operas... but this seemed especially run-of-the-mill. Is the pot boiling over?
