There—a driveway, in which sat a big white four-door Chevy Silverado truck; the driveway led to a carport.
Wolfe ducked into the car port. The concrete and steel roof would protect him for now. But how low could the drone fly and still fire with effect? If it came down low enough and got him in its sights, he’d have to try the Mack 10 on it, see if he could shoot it down. But it was probably armored against light weapon firepower.
He could hear it whirring overhead as they looked for him…
Wolfe shoved the .45 in his belt, and concentrated on the PearcePhone.
He knew how to hack into a drone—he’d worked up methods of blocking hacker transmissions from the Iranians. Could this drone be protected—by technology Wolfe himself had helped create? If so, that was another cold-blooded irony.
But as far as he knew, the methodology hadn’t yet been adopted. The Army took its time with testing.
“I guess I’ll find out,” he muttered, as he directed the phone to scan for the drone’s GPS receivers.
Pearce had a program for hacking a GPS receiver. And GPS is what drones used to orient themselves. The remote controls relied on GPS—you could tell the drone to go straight, but it used GPS to work out to do it relative to the controller.
“Spoofing” was the key—in this case, generating counterfeit GPS signals… He needed to get his phone’s signals aligned with the original signals used by the drone; then he had to increase signal strength, to override the GPS tracking loops. That would give him control of the receiver’s sense of location and time.
The drone was humming closer, as Wolfe pecked at the phone with his cold, half-numb fingers.
He glanced up—and saw its shadow on the driveway. The shadow was getting larger. Meaning the drone was getting lower. The controller had figured out where he was and was sending the drone lower to try for a kill shot. He could hear its rotors whirring, saw dust rising, swirling under their pressure…
“There he is sir!” came Starling’s voice through the phone’s hack into the house’s voice activation system. “All you have to do is get him in your sights!”
The phone chimed—and Wolfe saw the words GPS receiver located. Lock in?
He clicked on yes.
The drone was still lowering… and there it was, vibrating in the rotor wash, its camera swiveling to take Wolfe in; its gun muzzles training on him.
He looked at the GPS control grid—found, Veer Left. He tapped it—and the drone suddenly veered left. Firing a moment after it turned.
“Ha!” Wolfe said. His heart was pounding—he’d come within a split second of being shot down.
The drone fired a few more bullets but now its rounds were aimed to its left, away from Wolfe, and they spanged off the building’s shutters.
Wolfe found another directive: Circle area. Choose area diameter.
He chose fifty yards.
The drone suddenly headed out, circling the building…
“What the hell!” said the voice. “Starling, what’s going on?”
“Sir, I think he’s spoofed the drone, sir! He’s gotten control of its GPS—that’s the vulnerable point… We really should have used those GPS input protocols recommended by—”
“Starling, don’t say it!”
“Sir, yes sir!”
“It’s sure getting hot in here,” said the Graywater.
“Oh, hell and damn, he’s got control of the heat!”
“Who is this guy?” the Graywater muttered.
Wolfe put on the speakerphone and said, ””Verrick—I really should just cook you alive. It’d take a long time. Maybe hours. I guess you’d probably get through the door. Or call someone to get you out. But maybe not. I’ve shut down the house’s wifi and cell output! The house doesn’t have landlines—so how are you going to call out?”
“Who are you?” Verrick demanded.
“I’m the guy who can turn the lights out on you…” Wolfe tapped the superimposed interface on the PearcePhone.
“Hey! The lights went out!” the Graywater yelled.
“I can see that, you moron!” Verrick snapped. “Go get some lanterns—there, in that storage room. And stop panicking! He’s just messing with your head!”
“But you can have the lights back on, if you want…” Wolfe said, as if it had just occurred to him.
He switched them back on.
“Hey now they’re on—!”
“I can see that too, you idiot!”
“But on second thought,” Wolfe said, “why not give you a dark room to chill out and think things over in…”
He switched the lights out again—just as Verrick growled, “That voice! I know that voice!”
“Do you know my voice, Verrick?” Wolfe asked. “You should! Before I’m done you’ll hear my voice plenty—loud and proud! It’ll be the last thing you ever hear!”
“Wolfe!”
“Bingo, Verrick! The guy you framed and left in federal prison for a year! Big mistake!”
“My mistake was not killing you!”
“It’s a mistake you can’t undo, Verrick! You’ll never get another chance!”
“Sir—he’s hearing you! But the cell phones aren’t on! He’s got to be listening in through speech recognition!”
“That means he’s been hearing us all along!”
“That’s right, Verrick. Now how about telling me about the Iceberg Project? And about Purity?”
“Wolfe—I’ll tell decadent socialist scum like you nothing! You go to hell!”
“Hell is all about heat, Verrick! How’s the temperature in there?”
“You, get that door open! There are tools in the maintenance room! Make it quick!”
“Yes sir!” the Graywater replied.
“You come outside,” Wolfe said, heading out from under the carport, “I’ll shoot you dead!”
He glanced up, saw the drone circling the house.
“Sir—I might be able to free up the GPS, sir!”
“Starling—shut up! He’s listening! How can anyone be so smart at some things and so stupid at others?”
“Sir, I don’t know, sir!”
“It was a rhetorical… never mind! Just…”
“Yes sir! I’m sorry! It’s this heat… this heat!”
“Stop whining!”
Wolfe had reached the front door, heard a hammering on the other side. But he had something else to deal with first…
He brought up the phone’s hack of the UAV, and made the drone change course, so it was heading for the front of the house…
The hammering became a strident clanging. The door beside the lock was starting to bulge outward…
“You ready to talk, Verrick?” Wolfe demanded. “Cooking alive’s going to be very unpleasant! I really think I’m going to have to shut the phone off pretty soon. The screaming of men baking to death is just something I don’t care to listen to. I’m too sensitive a guy…”
“You’re going to die slowly when I get my hands on you, Wolfe!”
“Come on, Verrick! You may as well tell me the facts! I know that you’re planning a—”
Suddenly the doorlock snapped and the door flew open.
