Patience . . . Watching the cassette roll. Listening.

It was twenty minutes later that he heard what he’d been hoping for on the tape. He smiled. Okay, good. He collected his Model 40 in the Fender guitar case, snug as a baby, and walked to the refrigerator. He cocked his head. The noises had stopped. It didn’t shake any longer. He felt a bit of relief, less cringey, less crawly, thinking of the worm inside, now cold and still. It was safe to leave. He picked up his backpack and left the dim apartment with its pungent cat musk, dusty wine, and a million trails of disgusting worms.

Into the country.

Amelia Sachs sped through a tunnel of spring trees, rocks on one side, a modest cliff on another. A dusting of green, and everywhere the yellow starbursts of forsythia.

Sachs was a city girl, born in Brooklyn General Hospital, and was a lifetime resident of that borough. Nature, for her, was Prospect Park on Sundays or, on weekday evenings, Long Island forest preserves, where she’d hide her black sharklike Dodge Charger from the patrol cruisers prowling for her and her fellow amateur auto racers.

Now, at the wheel of an Investigation and Resources Division rapid response vehicle—a crime scene station wagon—she punched the accelerator, swerved onto the shoulder, and passed a van that sported an upside-down Garfield cat suctioned to the rear window. She made the turnoff that took her deep into Westchester County.

Lifting her hand off the wheel she compulsively poked her finger into her hair and worried her scalp. Then she gripped the plastic wheel of the RRV once again and shoved the accelerator down until she burst into the suburban civilization of strip malls, sloppy commercial buildings, and fast-food franchises.

She was thinking about bombs, about Percey Clay.

And about Lincoln Rhyme.

Something was different about him today. Something significant. They’d been working together for a year now, ever since he’d shanghaied her away from a coveted assignment with Public Affairs to help him catch a serial kidnapper. At the time Sachs had been at a low point in her life—an affair gone bad and a corruption scandal in the department that disillusioned her so much that she wanted out of patrol altogether. But Rhyme wouldn’t let her. Simple as that. Even though he was a civilian consultant he’d arranged for her transfer to Crime Scene. She protested some but soon gave up the pretense of reluctance; the fact was that she loved the work. And she loved working with Rhyme, whose brilliance was exhilarating and intimidating and—an admission she made to no one—goddamn sexy.

Which wasn’t to say that she could read him perfectly. Lincoln Rhyme played life close to his chest and he wasn’t revealing all to her.

Shoot first . . .

What was that all about? You never discharged a weapon at a crime scene if there was any way to avoid it. A single gunshot would contaminate a scene with carbon, sulfur, mercury, antimony, lead, copper, and arsenic, and the discharge and blowback could destroy vital trace evidence. Rhyme himself told her of the time he’d had to shoot a perp hiding at a scene, his biggest concern being that the shots had ruined much of the evidence. (And when Sachs, believing she’d at last outthought him, said, “But what did it matter, Rhyme? You got the perp, right?” he’d pointed out acerbically, “But what if he’d had partners, hm? What then?”)
