The Sleeping Doll

clues signal lying with some consistency: One is a very slight increase in the pitch of the voice, because lying triggers an emotional response within most people, and emotion causes vocal cords to tighten. The other signal is pausing before and during answering, since lying is mentally challenging. One who’s lying has to think constantly about what he and other people have said previously about the topic, then craft a fictitious response that’s consistent with those prior statements and what he believes the interrogator knows.
    In her conversation with the guard, Dance had become aware that at several points his voice had risen in pitch and he’d paused when there was no reason for him to. Once she caught on to this, she looked back to other behaviors and saw that they suggested deception: offering more informationthan necessary, digressing, engaging in negation movement—touching his head, nose and eyes particularly—and aversion, turning away from her.
    As soon as there’s evidence of deception, an interview turns into an interrogation, and the officer’s approach changes. It was at that point in their conversation that she’d broken off the questions about Pell and had begun talking about topics he’d have no reason to lie about—his personal life, the Peninsula, and so on. This was to establish his baseline behavior.
    As she was doing this, Dance performed her standard four-part analysis of the subject himself, to give her an idea of how tactically to plan the interrogation.
    First, she asked, what was his role in the incident? She concluded that Tony Waters was at best an uncooperative witness; at worst, an accomplice of Pell’s.
    Second, did he have a motive to lie? Of course. Waters didn’t want to be arrested or lose his job because intentionally or through negligence he’d helped Daniel Pell escape. He might also have a personal or financial interest in aiding the killer.
    Third, what was his personality type? Interrogators need this information to adjust their own demeanor when questioning the subject—should they be aggressive or conciliatory? Some officers simply determine if the subject is an introvert or extrovert, which gives a pretty good idea of how assertive to be. Dance, though, preferred a more comprehensive approach, trying to assign code letters from the Myers-Briggs personality type indicator, which includes three other attributes in addition to introvert or extrovert: thinking or feeling, sensing or intuitive, judging or perceiving.
    Dance concluded that Waters was a thinking-sensing-judging-extrovert, which meant that she could be more blunt with him than with a more emotional, internalized subject, and could use various reward-punishment techniques to break down the lies.
    Finally, she asked: What kind of “liar’s personality” does Waters have? There are several types: Manipulators, or “High Machiavellians” (after the ruthless Italian prince), lie with impunity, seeing nothing wrong with it, using deceit as a tool to achieve their goals in love, business, politics—or crime. Other types include social liars, who lie to entertain, and adaptors, insecure people who lie to make positive impressions.
    She decided that, given his career as a life-long prison guard and the ease with which he’d tried to take charge of the conversation and lead her away from the truth, Waters was in yet another category. He was an “actor,” someonefor whom control was an important issue. They don’t lie regularly, only when necessary, and are less skilled than High Machs, but they’re good deceivers.
    Dance now took off her glasses—chic ones, with dark red frames—and on the pretense of cleaning them, set them aside and put on narrower lenses encased in black steel, the “predator specs” she’d worn when interrogating Pell. She rose, walked around the desk and sat in the chair beside him.
    Interrogators refer to the immediate space around a human being as the “proxemic zone,” ranging from “intimate,” six to eighteen inches, to “public,” ten feet away and beyond. Dance’s preferred space for interrogation was within the intermediate “personal” zone, about two feet away.
    Waters noted the move with curiosity but he said nothing about it. Nor did she.
    “Now, Tony. I’d just like to go over a few things one more time.”
    “Sure, whatever.” He lifted his ankle to his knee—a move that seemed relaxed but in fact was a glaring defense maneuver.
    She returned
