Innocent Blood

Innocent Blood (1980) is an English crime novel by P. D. James. Unlike her Adam Dalgliesh mysteries it is not a detective story but closer to a psychological thriller and was the first of James' novels to step outside the detective genre. (She had published a non-fiction account of a real crime, The Maul and the Pear Tree, in 1971.) It follows the story of a young woman searching for her biological roots, having known since childhood that she was adopted, and the dark truths that she uncovers.
