Which, of course, Thom would have insisted on anyway.

Old mother hen.

In a few minutes he was freed from the vehicle and he wheeled his new chair, which he quite liked, up to Amelia Sachs.

Rhyme regarded her with some scrutiny. She was in pain, though trying to cover. But her discomfort was obvious to him.

“Where’s Ron?”

“Walking the grid in the house.”

Rhyme grimaced as he looked at the smoldering trees and boxwood and the smoke trickling out of the expensive Colonial. Fire department fans had largely exhausted the worst of the fumes. “Didn’t anticipate a diversionary charge, Sachs. Sorry.”

He was furious with himself for not considering it. He should have known Unsub 516 would try something like that.

Sachs said only, “Still, you came up with a good plan, Rhyme.”

“Well, had the desired result,” he conceded with some, but not too much, modesty.

The criminalist had never suspected Spencer Boston of anything more than leaking the STO order. True, as Sachs had pointed out, both Boston and Moreno had a Panama connection. But even if Boston had  been involved in the invasion, Moreno was just a boy then. They couldn’t have known each other. No, Panama was just a coincidence.

But Rhyme had decided that Metzger’s administrations director would make excellent bait, because whoever was  behind the plot – the unsub’s boss – would want to kill the whistleblower too.

This was the help he’d enlisted Shreve Metzger for. Ever since he’d learned of the investigation last weekend, Metzger had been contacting everyone involved in the STO drone project and telling them to stonewall and dump evidence. These encrypted texts, emails and phone calls were sent to people within NIOS but also to private contractors, military personnel and Washington officials. This was how Unsub 516’s boss had known so much about the case. Metzger had been feeding everyone virtually real time intelligence about what was going on, so passionate was he about keeping the STO program going. The boss, in turn, briefed the unsub.

But who exactly was that person?

At Rhyme’s insistence, Metzger had called these same people an hour ago and told them the whistleblower had been identified as Spencer Boston and they should destroy any evidence linking them to the man.

Rhyme suspected that the mastermind behind the plot to kill Moreno’s guard would order Unsub 516 to show up in Glen Cove to eliminate Boston.

So the administrations director, along with Sachs and Pulaski, waited inside. NYPD and Nassau County tactical forces took up hidden positions nearby, a helicopter from Emergency Service included. The noisy wood chipper, to cover up the sound of the aircraft, had been Ron Pulaski’s idea.

The kid was on a roll.

Rhyme now looked over Unsub 516, sitting shackled and cuffed on the front lawn of Boston’s house, about thirty feet away. His hand was bandaged but the wound didn’t seem to be too serious. The compact man gazed back at the authorities placidly, then turned his full attention to what seemed to be an herb garden nearby.

Rhyme said to Sachs, “Wonder how much work it’ll be to find out who he’s working for. I don’t suppose he’ll be very cooperative in naming the mastermind.”

“He doesn’t need to be,” Sachs said. “I know  who he works for.”

“You do?” Rhyme asked.

“Harry Walker. At Walker Defense Systems.”

The criminalist laughed. “How do you know that?”

She nodded at the unsub. “When I went out to the company to look for the airstrip? He’s the one who came to get me in the waiting room and took me to see Walker. By the way, he was really a flirt.”

His name was Jacob Swann, the security director for Walker Defense Systems.

Swann was former military but had been drummed out – if that was what they still called it – for excessive interrogation of suspects in Iraq. Not waterboarding but removing skin from several insurgents. Some other body parts had been removed too. “Expertly and slowly,” the report said.

Further datamining revealed that he lived alone in Brooklyn, bought expensive kitchen items and took himself to fine restaurants frequently. He’d had two emergency room visits in the last year. One was for a gunshot wound, which he claimed was inflicted by an unseen hunter when he was out after some venison. The second was for a bad cut on his finger, which he attributed to a knife slipping off a Vidalia onion when he was preparing a dish.

The first would have been a lie, the second probably true, Rhyme guessed, considering what they now knew was Swann’s hobby.

Combine those ingredients with caviar and vanilla and you have a real expensive dish that’s served at the Patchwork Goose…

A car pulled up near the police tape, an older model Honda in need of some bodywork.

Nance Laurel, in her white blouse and navy suit, cut the same as her gray one, climbed out. She was rubbing her cheek and Rhyme wondered if she’d just applied more makeup. The assistant district attorney approached and asked if Sachs was all right.

“Fine. Little tussle. But he got the worst of it.” A nod at Swann. “He’s been read his rights. He hasn’t asked for a lawyer but he’s not being cooperative.”

“We’ll see about that,” Laurel said. “Let’s talk to him. I may need your help, Lincoln. We’ll bring him over here.”

“Not necessary.” He glanced down at the Merits wheelchair. “They tell me it’s particularly good on rough terrain. Let’s find out.”

Without a hesitation the chair sped over the lawn straight to the perp.

Nance Laurel and Sachs joined him. The ADA looked down at Swann. “My name is–”

“I know who you are.”

One of her trademarked pauses. “Now, Jacob, we know Harry Walker’s behind this. He had you plant fake intelligence to trick NIOS into assassinating Robert Moreno as a cover so you could kill his guard, Simon Flores, who was blackmailing Walker. You were at the South Cove Inn when it happened, waiting for the drone strike. Just afterward, before the rescue workers got there, you broke into suite twelve hundred and stabbed Flores and Eduardo de la Rua to death. Then you went to Flores’s lawyer’s office in Nassau and tortured and killed him, stole the documents Flores had left for safekeeping – the documents Walker was worried would be made public.

“After my investigation started, Metzger gave Walker updates and names – to destroy evidence and be on guard against the police running the case. But Walker told you to do more than that – to eliminate witnesses and the investigators. You killed Annette Bodel, Lydia Foster and Moreno’s driver, Vlad Nikolov–” Laurel glanced toward Sachs and Rhyme. “Officers in Queens found his body in the basement of his house.”

Swann merely looked down at his bandaged hand and said nothing.

The prosecutor continued, “You also arranged with some associates in Nassau to kill Captain Rhyme and others working with him down there… And then there was this.” She offered a nod around the marred suburban landscape, resembling a combat zone.

The depth of this information, laid out so unemotionally by Nance Laurel, must have taken Swann by surprise but he hesitated only a moment then said in a calm voice, “First of all, as for this incident…” He nodded at Boston’s house. “Regarding the weapons, all three of us have Class Three federal firearms licenses and concealed carry permits valid in the state of New York. Now, in my job at Walker Defense, I’m involved in national security. We came here on a tip that Spencer Boston represented a dangerous security leak. My associates and I were simply going to check that out and discuss the matter with him. Next thing I know, tactical troops were threatening us. They claimed they were NYPD but how was I supposed to know? Not a single person offered me their identification.”
