Chapter 144: Mutual Mockery

He turned and followed Isabelle into the villa, setting the paper bag down on the kitchen island.

Isabelle poured herself a glass of water and glanced at him. "Didn't you leave?"

"Passed by a supermarket, picked up some fruit." Sean lied without batting an eye. His gaze drifted over Isabelle in a way that seemed almost casual, still probing. "He rushed to the airport in the middle of the night, must've been something urgent?"

Isabelle took a sip of water, her expression unreadable.

She had noticed something was off with Sean all evening. She just didn't feel like dancing around it.

"He's busy with work. We've been close friends for years. Tonight we were just going over some data."

Close friends.

The words left Isabelle's mouth without any hesitation, calm, steady, and not open to question.

The darkness in Sean's eyes faded instantly, replaced by a deep, quiet satisfaction.

He knew Isabelle had no interest in lying. If she said they were just friends, then that's all they were.

"Get some rest." Sean didn't push further. He knew when to stop.

After leaving the villa, Sean settled back into the Maybach. He pulled out his phone and sent Flynn a short, direct message: [Drop all background checks on Caius. Pull the surveillance team.]

She had vouched for him. That was enough. Sean would give the man his full respect, and stay well clear of her lines.

Life moved on. The holidays arrived before long.

Washington's late autumn carried a biting chill.

Isabelle had barely left the villa these past few days, spending almost all her time in the basement.

Lines of cold blue code scrolled endlessly across the screens down there.

Isabelle sat in her chair, fingers flying across the keyboard.

She was tracing the money trail from the bombing at Base Seven, all those years ago.

The dark web data Caius had brought was enormous. She had to work through it piece by piece, hunting for the mole buried somewhere inside Syndicate's upper ranks.

Time ticked by. The clock on the wall read two in the morning.

Isabelle pressed her fingers against her temples, rubbing at the ache behind her eyes, then hit enter and encrypted the handful of suspicious accounts she'd flagged. She closed the laptop, stood up, and rolled her stiff shoulders. Time to go upstairs.

She had just set foot on the basement stairs when the tactical terminal on her wrist gave a faint, almost imperceptible buzz.

Isabelle froze. Her eyes sharpened in an instant, all traces of tiredness gone.

She glanced down at the screen.

The villa's infrared thermal imaging system had been triggered.

On the display, a vivid red human outline was moving along the outer wall, avoiding the standard camera blind spots, closing in on the front door with the quiet precision of someone who had done this many times before.

Not your average thief.

Whoever this was moved with purpose and economy. Trained. Professional.

The corner of Isabelle's mouth curved into something cold.

She didn't touch a single light switch. The entire ground floor of the villa sank into absolute darkness.

Isabelle reached into the hidden pocket of her cargo pants and pulled out the black surgical blade, the one forged from meteorite iron. She gave it a small turn between her fingers, and the edge caught a faint glimmer in the dark.

Like a leopard that had been still for too long, she pressed herself silently against the wall beside the front door.

Outside, the figure was working through the electronic lock with a custom decoder.

A soft click cut through the silence of the night.

The lock disengaged. The figure moved to push the door open.

Isabelle yanked it open first.

The figure clearly hadn't expected anyone to be awake, let alone moving toward them. There was a half-second of hesitation.

Half a second was enough.

Isabelle's left hand shot out and seized the figure by the collar. Using the momentum of their forward lean, she wrenched them hard into the entryway.

The door slammed shut behind them. Isabelle kicked the deadbolt in the same motion.

The intruder recovered fast, planting their feet mid-stumble, flipping a combat knife with one hand and driving it straight at Isabelle's throat.

Isabelle didn't step back. She stepped in. A slight shift of her body took her clear of the blade, and in the same breath her right hand drew the surgical knife upward in a sharp, precise arc aimed directly at the wrist holding the knife.

The intruder felt a flash of cold at the wrist, then a spike of pain. The knife hit the floor.

They hadn't expected this, hadn't expected someone who looked so slight to move like that.

One exchange, and they already knew. This wasn't a fight they could win.

They made the call immediately. Forget the objective. Get out.

They turned and bolted for the nearest floor-to-ceiling window, angling to smash through it.

"Going somewhere?"

Isabelle's voice was flat and frozen. She was already moving, fast, like something released under tension.

The intruder's hand had barely touched the window handle when Isabelle was right behind them. A hard, whipping kick caught them square in the lower back.

There was a dull grunt. The intruder slammed into the blast-resistant glass and bounced off, hitting the floor.

They rolled to their feet, trying to use the sofa as cover and cut toward the side door.

Isabelle was faster. She stepped up onto the sofa's edge and launched herself into the air. The surgical blade traced a cold arc in the darkness, cutting off every possible escape route.

Three times the intruder tried to break out. Three times Isabelle forced them back with strikes that left no room for argument.

On the final exchange, Isabelle caught their left arm from behind and wrenched it. The sound of bone grinding out of socket was sharp in the dark.

She swept their legs at the knee and dropped them, pressing the blade flat against the carotid artery.

The intruder went down on their knees, cold sweat soaking through their clothes, completely still.

The edge of the blade rested against the artery without moving. A half-millimeter more pressure, and that would be the end of it.

The intruder knelt on the cold floor, sweat dripping from their temple and hitting the tile. They had been trained to hold up under pressure, serious training. But kneeling here, in the dark, with this blade at their throat, the fear was something else. Real in a way that got into the bones.

Isabelle's free hand came down in a precise, brutal chop to the right shoulder joint.

The crack was quiet but final. The arm went limp.

"Don't move," Isabelle said. Her voice was perfectly level. "Or I open your airway the fast way."

She pressed one knee into the small of his back and ran her free hand over him, fast, methodical, like water finding its way through cracks.

The hidden seam inside the collar. The adhesive patch behind the ear. The recessed compartment in the heel of the tactical boot.

Fifteen seconds, maybe less. Three micro-sized listening devices and two high-precision GPS trackers, all accounted for.

Isabelle didn't look at them twice. She closed her fingers and crushed each one into a small handful of useless metal, then dropped the pieces into the signal-shielding box on the floor beside her.

Then she grabbed the intruder by the back of the collar and dragged him, the way you'd drag something that had already stopped mattering, straight down into the basement.
