I cannot get my head around this book at all. Considering it's called "The Christie Affair" there isn't a huge amount of Agatha in it. Protagonist Nan is clearly intended to be based on Nancy Neele, though I can't imagine the second Mrs Christie's relatives are overly enamoured with the portrait presented of her here. If the author had simply built a book from the storyline around Nan, then I imagine it would have been a decent read. As it stands, the link to Agatha Christie feels tenuous at best and downright disrespectful at worst. Clearly this book wasn't for me.
