I love PD James (and here, here ). But I did not love Innocent Blood, although it has been praised as one of her finer books. It’s more ambitious than the others, since whatever murders occur as either planned or solved long ago, so the focus is on an 18-year old who discovers her surprising biological mother. Sadly the story becomes less and less believable, albeit starting from a wonderful description of the complicated relationship she has with her mother, whom she considers to be lacking in many ways, and her father, whom she admires but also resents. After that, too may details just don’t add up and I found myself focusing on them and losing interest in the narrative.
