The Final Gambit of a Dead Man’s Hand
The park lake was a sheet of gray glass under the overcast sky, the surface barely rippling as a light breeze moved across it. Julian stood at the edge of the water, a tablet in one hand and a portable signal booster in the other. Behind him, Dorian had the mobile command van’s side panel open, a small dish antenna angled toward the sky.
“I’m getting the telemetry feed now,” Dorian said, his voice clipped over the earpiece. “It’s coming from the northeast. Two miles out. Altitude, three hundred feet. Speed, forty knots.”
Julian didn’t answer. His eyes were fixed on the tablet’s screen, where a map of the city was overlain with a single red dot moving steadily toward the school zone. The Hunter-Killer drone was a six-rotor craft, military-grade, with a payload capacity that could carry enough explosive to level a small building. Cole had bought it on the black market, no doubt through one of the Ravenwood family’s old contacts in Eastern Europe.
The thought made Julian’s stomach turn, but he forced it down. Panic was a luxury he couldn’t afford.
“Dorian, I need the drone’s firmware version. Check the handshake logs from the initial signal intercept.”
“Already on it.” There was a pause, then Dorian’s voice came back. “Version 4.2.1. Build date, three years ago.”
Julian’s breath caught in his throat. Version 4.2.1. That was the build he’d worked on during his brief stint at Aether Dynamics, before he’d walked out over the ethics violations. He’d written the targeting algorithm for that firmware. He’d also written a backdoor—a deliberate flaw in the pathfinding logic, designed to force a recalibration loop if the drone’s GPS signal was fed a specific set of coordinates.
It was a bug he’d kept quiet about, a silent insurance policy against the day someone might use his work for something like this.
“I need a clear line of sight to the drone’s signal,” Julian said, moving toward the van. “And I need you to spoof a GPS signal. Same frequency, same encryption key. Can you do that?”
Dorian already had a laptop open, his fingers flying across the keyboard. “Give me thirty seconds. I’ll piggyback on the city’s traffic management satellite. They’ve got a repeater on the water tower two blocks over.”
Julian climbed into the van, the tablet clutched in his hand. The interior was cramped, filled with monitors and cables, but it was the most secure communications hub they had. He plugged the tablet into the van’s system, and the screen flickered to life with a new set of data.
The drone’s signal was strong. Too strong. It was broadcasting on an open channel, which meant Cole wanted them to know. Wanted them to watch.
“He’s trying to break us,” Julian muttered.
“Then we don’t break,” Dorian said. “Got the spoof. Feeding it now. The drone’s current GPS coordinate is 34.0522, -118.2437. I’m going to inject a new target: 34.0530, -118.2420. That’s the center of the lake.”
“Do it.”
The screen showed the red dot hesitate for a fraction of a second, then begin to shift course. The drone was recalibrating, its internal systems trying to reconcile the conflicting data. Julian watched the altitude tick down from three hundred to two hundred and fifty feet.
“It’s following the spoof,” Dorian said, a note of disbelief in his voice. “It’s actually working.”
“It’s not supposed to work,” Julian said. “The backdoor is designed to trigger a recalibration loop, not a full reroute. If the drone’s internal compass is still active, it’ll override the GPS within sixty seconds.”
“Sixty seconds is all we need.”
Julian’s gaze locked on the tablet. The dot was descending now, its path curving toward the lake. The altitude read two hundred feet. Then one fifty. One hundred.
“Come on,” Julian whispered. “Come on.”
The drone’s signal flickered. The red dot on the map stuttered, then steadied. Julian’s heart hammered against his ribs. The backdoor was holding, but for how long?
“It’s fighting the spoof,” Dorian said. “I’m seeing a secondary GPS signal trying to re-establish lock. It’s Cole. He’s manually overriding.”
“Can you jam it?”
“Not without a direct line of sight. The van’s antenna isn’t powerful enough.”
Julian’s mind raced. The drone was at seventy-five feet now, its rotors kicking up spray from the lake’s surface. In another ten seconds, it would be in the water. But if Cole’s override succeeded, it would veer off course, heading straight for the school.
He looked at the tablet, at the lines of code scrolling across the screen. The targeting algorithm. The flaw he’d planted.
And then he saw it.
The recalibration loop wasn’t designed to accept a new destination. It was designed to reject the current one. If the drone’s internal compass was overridden, the loop would terminate, and the drone would return to its last commanded position.
But what if the loop was forced to accept a destination that didn’t exist?
“Dorian, I need you to feed the drone a coordinate that’s mathematically impossible. Something that doesn’t exist on Earth.”
“Like what?”
Julian’s fingers flew across the tablet’s keyboard. “Like 90 degrees north, 0 degrees east. The North Pole. The drone’s internal systems will recognize it as a valid coordinate, but the GPS will reject it as an error. The loop will panic and default to crash protocol.”
Dorian stared at him for a long moment, then a slow grin spread across his face. “You’re a genius.”
“I’m a bastard who left a backdoor in his own code. Call it what you want.”
Dorian’s fingers moved. The drone’s signal wavered, then steadied again. The altitude was fifty feet now. The spray was visible from the shore, white foam churning against the dark water.
“Feeding the coordinate now,” Dorian said.
The tablet screen flickered. The red dot shimmered, then began to pulse. The drone’s internal system was rejecting the new data, trying to reconcile the conflict. Julian watched the altitude tick down to forty feet. Thirty.
And then the drone stopped.
It hovered, motionless, ten feet above the lake’s surface. The rotors were spinning, but the craft was frozen, caught between two conflicting commands. Julian could see it from the van’s window, a dark shape against the gray sky.
“The loop is holding,” Dorian said. “It’s not moving.”
Julian didn’t answer. He was staring at the tablet, watching the code scroll. The backdoor was doing exactly what he’d designed it to do: forcing the drone to choose between two impossible options. But if Cole had a manual override, he could still force the drone to crash into the school.
“I need you to cut the drone’s communication link,” Julian said.
“I can’t. The van’s antenna isn’t powerful enough to brute-force a shutdown.”
“Then we need to take it down.”
Dorian looked at him. “You mean physically?”
Julian’s gaze was fixed on the drone. It was still hovering, still frozen, but the rotors were starting to whine, the pitch rising. The internal systems were overheating, the conflict drawing more power than the battery could sustain.
“It’s going to burn out in about thirty seconds,” Julian said. “But if Cole forces a manual override before that, it’ll veer off course.”
“What do you want me to do?”
Julian’s jaw set firmly. He looked at the water, then at the drone, then back at the tablet. There was only one option left, and it was a gamble.
“Tell everyone to get back,” Julian said. “I’m going to blow it up.”
Dorian’s face went pale. “With what?”
“There’s a fire extinguisher in the corner. And a flare gun in the glove compartment.”
“That’s not a plan. That’s a suicide wish.”
“It’s the only plan we’ve got. The drone’s battery is about to overheat. If I hit it with the flare, the fuel might ignite the battery.”
“And if it doesn’t?”
Julian didn’t answer. He grabbed the flare gun from the glove compartment and stepped out of the van. The air was cold, the wind biting at his face. The drone was a hundred feet away, hovering over the lake, its rotors whining like a wounded animal.
He raised the flare gun.
The drone’s rotors pitched higher. The battery was overheating, the internal systems screaming. Julian took aim at the center of the craft, where the battery was housed.
And then he pulled the trigger.
The flare shot across the water, a bright streak of red against the gray sky. It hit the drone’s casing, bounced off, and fell into the lake.
For a moment, nothing happened.
Then the drone exploded.
The blast was a deafening roar, a shockwave of heat and sound that knocked Julian off his feet. He hit the ground hard, the air driven from his lungs. Shards of metal rained down around him, pattering into the lake like hail.
And then, silence.
Julian lay on the ground, staring up at the sky, his ears ringing. The drone was gone, nothing left but a smoking wreckage sinking into the lake.
His earpiece crackled. “Julian? Julian, are you there?”
It was Dorian’s voice, barely audible over the static.
“I’m here,” Julian said, his voice hoarse.
“Cole is in custody. The police got him at the Ravenwood estate. He tried to run, but security had already locked the gates.”
Julian closed his eyes, the cold ground pressing against his back. “And the school?”
“No casualties. The drone never got within a mile of it.”
Julian let out a breath he didn’t realize he’d been holding. He pushed himself to his feet, his legs unsteady, and looked at the lake. The wreckage was already spreading out, a slick of oil and metal on the dark water.
His phone buzzed.
He pulled it out of his pocket. The screen was cracked, but still functional. The message was from a secure line, one he’d set up years ago for emergencies.
It was a video feed.
The drone’s camera.
It had been transmitting all along, and Cole had been watching. Julian’s stomach turned as he stared at the feed, the grainy image of the park lake, the wreckage, the smoke still rising from the water.
The camera panned down, showing the wreckage. The rotors were still, the casing twisted and blackened. The battery was gone, blown to pieces by the flare.
His comms crackled.
It was Seraphina, her voice shaky but strong. “Julian. He’s asking for you. He wants a story. A happy one.”
