The Kill Room (Lincoln Rhyme 10)

"Good luck with that, Mr. Walker. Call me if you can think of anything, please." She handed him one of her cards--which, she suspected, he'd pitch out before she was halfway to the lobby.

Didn't matter.

Sachs had everything she needed.

CHAPTER 61

IN RHYME'S DARK PARLOR, redolent of trace materials burned into incriminating evidence by the gas chromatograph, Sachs pulled her jacket off and held up the brochure from Walker Defense.

Ron Pulaski taped it up on a whiteboard. The glitzy piece sat next to the kill order.

"So," Rhyme said, "what did it look like?"

"Pretty short and hidden between two buildings but I caught a glimpse from Walker's office. There was a windsock at one end and what looked like a small hangar at the other."

Sachs's mission had nothing to do with getting customer information or the names of people fabricating long-range rifles, which Rhyme knew Walker wouldn't divulge anyway. Her job was to find out as much about the company's products as she could--more than its preening and ambiguous website offered. And--most important--to find out if it had a length of asphalt or concrete that could be used as an airstrip; Google Earth had not been helpful in that regard.

"Excellent," Rhyme said.

As for the other products, they too were just what he'd hoped: instruments and devices for guidance, navigation and control systems, in addition to ammunition. "Gyroscopes, GPS sighting systems, synthetic aperture radar, things like that," Sachs explained.

The criminalist read through the brochure.

He said slowly, "Okay, we have our answer. The case is back on. Barry Shales did kill Robert Moreno. He was just a little farther away from the target than two thousand feet. In fact, he was here in New York when he pulled the trigger."

Sellitto shook his head. "We should've thought better. Shales wasn't infantry or special forces. He was air force."

Rhyme's theory, now supported by Sachs's legwork, was that Barry Shales was a drone pilot.

"We know his code name is Don Bruns and Bruns was the one who killed Moreno. The data show he was in the NIOS office downtown on the day the man died. He'd have been piloting a drone from some control facility there." He paused, frowned. "Oh, hell, that's the 'Kill Room' the STO refers to. It's not the hotel suite where Moreno was shot; it's the drone cockpit or whatever you call it, where the pilot sits."

Sachs nodded at the brochure. "Walker makes those bullets, they make gun sights and stabilization and radar and navigation systems. They've built or armed a specialized drone that uses a rifle as a weapon."

Rhyme spat out, "Look at the STO--there's a period after 'Kill Room,' not a comma! 'Suite twelve hundred' doesn't modify it. They're separate places." He continued, "Okay, this is all making sense now. What's the one problem with drone strikes?"

"Collateral damage," Sachs said.

"Exactly. A missile takes out terrorists but it also kills innocent people. Very bad for America's image. NIOS contracted with Walker Defense to come up with a drone that minimizes collateral. Using a precision rifle with a very big bullet."

Sellitto said, "But they fucked up. There was collateral."

"The Moreno assassination was a fluke," Rhyme said. "Who could've anticipated broken glass would be lethal?"

Sellitto gave a laugh. "You know, Amelia, you were right. This was a million-dollar bullet. Literally. Hell, given what drones cost, it's probably a ten-million-dollar bullet."

"How'd you guess?" Nance Laurel asked.

"Guess?" Sachs offered acerbically.

But Rhyme didn't need any defense. He was delighted with his deduction and was happy to explain:

"Trees. I was thinking of trees. There was poisonwood leaf trace on the bullet. I saw the tree outside the window of the suite. All the branches up to about twenty-five feet or so were cut back--because the hotel didn't want anyone touching the leaves. That meant the bullet struck Moreno at a very steep downward angle--probably forty-five degrees. That was too acute even for a shooter on the spit to aim high to correct for gravity. It meant the bullet came from the air.

"If Shales fired through the trees, that means he was using some kind of infrared or radar sighting system to quote see Moreno through the leaves. I was also curious why there was no pollution on the slug--from the fumes and crap in the air over the spit. A hot bullet would have picked up plenty of trace. But it didn't."

Pulaski said, "By the way, Lincoln, they're UAVs, unmanned aerial vehicles. Not drones."

"Thank you for the correction. Accuracy is everything. You're a wealth of knowledge."
