“He used to have one, and loved to take his little boy on ‘adventures.’ Picnics. Campouts on deserted islands. Discovering never-never lands, just the two of them. So imaginative and wistful—very much a child himself, really. It seems last time he was deployed, Shandy sold a lot of his things. Quite considerate, that one. I’m not sure he even owns a car anymore. But he’s resourceful. Light and quick on his feet. And covert, no doubt. Probably learned that over there.” She means Iraq.

Scarpetta is thinking about Marino’s flat-bottom bass boat with its powerful outboard engine, bow-mount trolling motor, and oars. His boat that he hasn’t used for months and doesn’t even seem to think about anymore. Especially of late. Especially since Shandy. She would have known about the boat, even if they’d never gone out in it. She could have told Will. Maybe he borrowed it. Marino’s boat should be searched. Scarpetta wonders how she will explain all this to the police.

“Who was going to take care of Shandy’s little inconvenience? The body. What was my son supposed to do?” Dr. Self says. “That’s what happens, isn’t it? One person’s sin becomes your own. Will loved his son. But when Daddy goes marching off to war, Mommy has to be both parents. And in this instance, Mommy is a monster. I’ve always despised her.”

“You’ve supported her,” Scarpetta says. “Handsomely, I might add.”

“Let’s see. And you know that? Let me guess. Lucy’s invaded her privacy, probably knows what she has—or had—in the bank. I wouldn’t have ever known my grandson was dead if Shandy hadn’t called. I suppose the day the body was found. She wanted money. More of it. And my advice.”

“Is she and what she told you why you’re here?”

“Shandy has managed to do a rather brilliant job of blackmailing me all these years. People don’t know I have a son. They certainly don’t know I have a grandson. If these facts were known, I would be viewed as neglectful. A terrible mother. A terrible grandmother. All those things my own dear mother says about me. By the time I became famous, it was too late to go back and undo my very deliberate distancing. I had no choice but to continue it. Mommie Dearest—and I mean Shandy—kept my secret in exchange for cashier’s checks.”

“Now you intend to keep her secret safe in exchange for what?” Scarpetta says. “She abused her son to death and you want her to get away with it, in exchange for what?”
