" I used to believe, bless my naive little heart, that I had something to offer the robbed dead. Not revenge—there’s no revenge in the world that could return the tiniest fraction of what they’ve lost—and not justice, whatever that means, but the one thing left to give them: the truth. I was good at it. I had one, at least, of the things that make a great detective: the instinct for truth, the inner magnet whose pull tells you beyond any doubt what’s dross, what’s alloy and what’s the pure, uncut metal. I dug out the nuggets without caring when they cut my fingers and brought them in my cupped hands to lay on graves, until I found out—Operation Vestal again—how slippery they were, how easily they crumbled, how deep they sliced and, in the end, how very little they were worth. In Domestic Violence, if you can get one bruised girl to press charges or go to a shelter, then there’s at least one night when her boyfriend is not going to hit her. Safety is a small debased currency, copper-plated pennies to the gold I had been chasing in Murder, but what value it has it holds. I had learned, by that time, not to take that lightly. A few safe hours and a sheet of phone numbers to call: I had never been able to offer a single murder victim that much. "
