Blood Work - Michael Connelly

"McCaleb believed there was a sacred bond between the victim and the investigator. All homicide copes understood this. Some took it straight to the heart. Some less, so, simply as a matter of psychological survival. But it was there in all of them. It didn't matter if you had religion, if you believed the soul of the departed watched over you. Even if you believed that all things ended with the final breath, you still spoke for the dead. Your name was whispered on the last breath. But only you heard it. Only you knew it. No toher crime came with such a covenant."

Though idealistic, such a pretty sentiment to think that if an injustice is done that ends your life, there would be someone there to seek vengence for you.
