Innocent blood - P. D. James

Philippa Palfrey, adopted as a child, believes herself to be the motherless, illegitimate daughter of an aristocratic father. At eighteen she exercises her right to find out the truth. What she discovers will change her life forever. Philippa embarks on a thrilling investigation, enters a new and terrifying world and soon comes to realize that she is not the only one interested in her parents' whereabouts.

From the bestselling author of Death Comes to Pemberley, Children of Men and Death in Holy Orders, Innocent Blood is both a mystery and a thriller, a superb novel that explores the themes of self-identity, blood ties, guilt and revenge.

P.D. James has been influential as a crime writer for many years and her writing is often compared to the work of authors such as Val Mcdermid, Ian Rankin and Peter Robinson.
