“Okay. Questions. Why only Mercedeses? Why stop at six? Why a Desert Eagle? Why more than one Desert Eagle? Why the little plastic animals? Why the manifesto? Why the combination of cool rational argument with hot religious language? Why the rigid repetition of—”

Holdenfield broke in, sounding exasperated. “David, each of those issues has been examined and discussed in detail—every one of them. The answers are clear, they make perfect sense, they form a coherent picture. I really don’t understand your point at all.”

“So you’re telling me that there was never a competing investigative premise?”

“There was never any basis for one. What the hell is your problem here?”

“Can you picture him?”

“Picture who?”

“The Good Shepherd.”

“Can I picture him? I don’t know. Is that a meaningful question?”

“I think so. What’s your answer?”

“My answer is that I don’t agree that it’s meaningful.”

“It sounds to me like you can’t picture him. Neither can I. Which makes me think there may be contradictions in the profile that are screwing up the gut-level process of imagining a face. Of course, he might be a woman. A woman strong enough to handle a Desert Eagle. Or he might be more than one person. But we’ll put that aside for now.”

“A woman? That’s absurd.”

“No time to argue that right now. I have one last question for you. Amid all the professional consensus, did you or any of your forensic-psych colleagues or anyone at the Behavioral Analysis Unit ever disagree among yourselves about anything in the case hypothesis?”

“Of course we did. There are always diverse opinions, differences in emphasis.”

“For example?”

“For example, the concept of pattern resonance emphasizes the transference of energy from an original trauma into a current situation—which makes the current manifestation essentially an inanimate vehicle that is given life by the past. The application of the imitation-instinct paradigm would give the current situation a greater validity of its own. It’s a repetition of a past pattern, but it does have life and energy of its own. Another concept that might apply is the transgenerational transmission of violence theory, which is a traditional learned-behavior model. There was ample discussion of all those ideas.”

Gurney laughed.

“What’s funny?”

“I can picture you guys staring out at a palm tree on the horizon and debating the number of coconuts on it.”

“Your point being?”

“What if the palm tree itself is a mirage? A group delusion?”

“David, if anyone in this conversation is delusional, it’s not me. Is that it for the questions?”

“Who benefits from the existing hypothesis?”

“What?”

“Who benefits from the—”

“I heard you. What the hell do you mean?”

“I have this sense of a sticky synergy connecting the facts of the case with the weak points of FBI methodology and the career dynamics of the professional forensic community.”
