Objectively I don’t think the ‘A Good Girl’s Guide to Murder’ trilogy was that well written, but to give Jackson credit the books are addictive, I got through the final instalment in just two days. ‘As Good as Dead’ inverts the regular structure where pip is forced to investigate into the person that she believes has begun stalking her, and therefore there is no initial murder to investigate, although I do think each book in the series has been a little better the last. 

It does callback to the previous two books and its been a little bit but seems to pull on evidence and events to create a ‘full circle’ structure that I could’ve sworn were already resolved and then therefore written over in the third book, but I can’t be sure on my memory of such. I also struggle with the fact that now after three books Pip has still gained absolutely no character development as a protagonist.
For all this I can't rank it too lowly though as the story did utterly enrapture me.
