This book by Cornwell is the most complex and heartfelt of all her books. Yes,it has all the mystery and intrigue and twists and turns that are required in a good crime novel. It's one of those that keep you reading well past midnight. But woven within is the story of love and human frailty ... and forgiveness and hope and trust ... and the strength required to live One Day At A Time while waiting for someone you love to take serious steps down the road to Recovery. I think that in this book Cornwall did what few writers of crime and forensic mystery rarely do: She wrote a fascinating, no holds barred legal thriller that is compelling right to the end, while leaving room for the flaws of even the best of humankind .... and the understanding and strength required to move past them to Recovery.
