“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.”
