The Stone Monkey

The phrase described one technique for physically searching a crime scene for clues, in which the CS officer covers the floor or ground in one direction, back and forth, like mowing a lawn, then turns perpendicular and covers the same ground again. The theory behind this method of searching is that you see things from one angle that you might miss when looking at them from a different angle. Although there were dozens of other methods of searching crime scenes, all ofthem faster, the grid—the most tedious type of search—was also the most likely to yield gold. It was the one that Rhyme insisted that Sachs use—just as he’d done with the officers and techs who worked for him at NYPD forensics. Thanks to Lincoln Rhyme, “walking the grid” had become synonymous with searching a crime scene among cops in the metropolitan area.
    Soon she was out of sight of the village of Easton and the only sign that she wasn’t alone was the diffuse flashing of the emergency vehicle lights, like blood pulsing through pale skin, unsettling and eerie.
    But soon the lights too vanished in the fog. The solitude—and a creepy sense of vulnerability—curled snug around her. Oh, man, I don’t like this. The fog was worse here and the sounds of the rain tapping loudly on the hood of her suit, the waves and the wind would mask an attacker’s approach.
    She slapped the grip of her black Glock pistol for reassurance and kept on the grid.
    “I’m going to go quiet for a while, Rhyme. I’ve got this feeling there’s somebody still here. Somebody watching me.”
    “Call me when you’re through,” he said. His hesitant tone suggested there was something more he wished to say but after a moment the line clicked off.
    Watch your back. . . .
    For the next hour, through the wind and rain, she searched the beach and road and the foliage beyond, like a child hunting for seashells. She examined the intact raft, in which she found a cell phone, and the deflated one, which two ESU officers had muscled up onto the beach. Finally she assembled her collection of evidence, shell casings, blood samples, fingerprints and Polaroids of footprints.
    Then she paused and looked around. Then she clicked on the radio and was patched through to a cozy town house light-years away. “Something’s funny, Rhyme.”
    “That’s not helpful, Sachs. ‘Funny’? What does that mean?”
    “The immigrants . . . ten or so of them, they just vanish. I don’t understand it. They leave a shelter on the beach then cross the road and hide in the bushes. I see the prints in the mud on the other side of the road. Then they just disappear. I guess they’ve gone inland to hide but I can’t find any tracks. And nobody’s going to give a ride to hitchhikers like them around here and none of the people in town saw any trucks waiting to pick them up. There aren’t any tire treads here anyway.”
    “All right, Sachs, you’ve just walked in the Ghost’s footsteps. You’ve seen what he’s done, you know who he is, you’ve been where he’s been. What’s going through your mind?”
    “I—”
    “You’re the Ghost now,” Rhyme reminded in a lulling voice. “You’re Kwan Ang, nicknamed Gui, the Ghost. You’re a multimillionaire, a human trafficker—a snakehead. A killer. You’ve just sunk a ship and killed over a dozen people. What’s in your mind?”
    “Finding the rest of them,” she answered immediately. “Finding them and killing them. I don’t want to leave. Not yet. I’m not sure why but I have to find them.” For an instant an image jolted her mind. She did see herself as the snakehead, filled with a salivating lust to find the immigrants and kill them. The sensation was harrowing. “Nothing,” she whispered, “is going to stop me.”
    “Good, Sachs,” Rhyme replied softly, as if he was afraid of breaking the thin wire that was connecting a portion of her soul to the snakehead’s. “Now, think about the immigrants.They’re being pursued by someone like that. What would they do?”
    It took her a moment to transform herself from a heartless murderer and snakehead into one of the poor people on that ship, appalled that the man she’d paid her life’s savings to had betrayed her in this way, had killed people she’d grown close to, perhaps family members too. And was now compelled to kill her.
    “I’m not going to hide,” she said firmly. “I’m getting the hell out of here as fast as I can. Any way I can, as far away as
