Becoming Lailah: Married to my Twin Sister's Billionaire Husband-Chapter 251: The Thieves 2

THEY MOVED like smoke through the museum’s ventilation system.

Mason and Ravenson were blurred streaks of darkness. Even with their powers limited, they were faster than any human eye could track, slipping through the corridors and silencing the night guards with a single, sleeping touch.

Carson’s illusion—a localized "electrical fire" in the west wing—had successfully drawn the majority of the security team away from the main exhibit.

Mailah and Grayson reached the grand hall. The Ember Sigil sat in the center of the room atop a white marble pedestal in a simple glass case.

To the museum, it was just a priceless artifact, but as they approached, Mailah could see it pulsing with a faint, inner orange glow as if it recognizes that its owner was near.

"The laser grid is active," Grayson whispered, stopping at the edge of the invisible security zone. "I can’t cross it without my heat signature setting off the silent alarm. Go. I will hold the shadow-veil around you so the cameras see only an empty floor."

Mailah took a deep breath, her heart hammering against her ribs—partly from fear, and partly from the lingering heat of Grayson’s kiss.

She stepped forward. Her night-silk suit felt like a second skin, making her feel nearly weightless as she navigated the path Arthur had described.

She reached the case. The glass was cold under her fingertips. Following the expert’s instructions, she carefully slid the counter-weight—a perfectly weighted replica Carson had spent three hours "perfecting"—under the edge of the heavy glass display.

Her hands shook. She had a 0.5-gram margin of error. If she was off by even a fraction, the weight plate would trigger the alarms and the police would be there in minutes.

Slowly, she lifted the glass just enough to reach inside. Her fingers closed around the Ember Sigil. It was surprisingly heavy and felt like holding a warm stone straight from a campfire.

She quickly swapped it with the replica, heart in her throat as she centered the fake on the sensor.

She lowered the glass.

Click.

She shut her eyes tight, expecting

Silence.

No sirens. No flashing lights. Just the quiet hum of the air conditioning.

She turned back to Grayson, the Sigil tucked safely into a lead-lined pouch at her waist.

He was watching her from the shadows, his expression one of pure, unadulterated awe.

And for the first time, he looked at her not just as a human girl, but as his equal.

"You did it," he breathed as she hurried back to the safety of his shadow.

He swept her up into a hug, spinning her once before setting her down. The joy in his eyes was the most human thing she had ever seen.

"We have to go," she whispered, though the way he was looking at her made her want to stay in his arms forever. Who knows when he would be like this again?

"Right," Grayson said, his face hardening back into the focused mask of a leader. He tapped his ear-piece. "Lucson, we have it. Move to Phase Three."

"Copy that," Lucson’s voice crackled in their ears. "But hurry. The Council’s messenger, Valerius? His black sedan just pulled into the parking lot. I don’t think he’s here for a private tour. He knows something is up."

The tension snapped back into place.

They weren’t out of the woods yet.

As they raced toward the secret exit, Mailah realized that while they had the Sigil, they had just caught more of the attention of the High Council.

And for the first time, she wasn’t just a girl caught in the crossfire. She was the thief who had just stolen back something powerful.

The weight of the Ember Sigil against Mailah’s hip was a constant, pulsing reminder of what they had just done. It wasn’t just a rock; it felt alive, a trapped heartbeat thrumming against the lead-lined pouch.

"Go," Grayson whispered, his hand firm on the small of her back.

They didn’t use the stairs.

Mason had already disabled the freight elevator’s sensors, and Ravenson was holding the heavy steel doors open with nothing but his shoulder and a look of pure boredom.

"Valerius is in the lobby," Ravenson rumbled, his voice like grinding stones. "He’s not looking at the art. He’s smelling the air."

"He’s a tracker," Grayson explained to Mailah as they slipped into the elevator. 𝚏𝕣𝕖𝚎𝚠𝚎𝚋𝚗𝐨𝐯𝕖𝕝.𝕔𝐨𝕞

The doors hissed shut, plunging them into a dim, metallic square of silence. "The Council uses his kind to find exiles who break the rules. If he catches our scent, the conservatorship becomes a death warrant."

The elevator lurched downward.

Mailah felt the floor drop, but her stomach stayed somewhere near her throat.

She looked at Grayson. Even in the dim light of the service lift, he was breathtaking. The silver light in his eyes hadn’t fully faded, and the shadow-veil he was holding around them made his edges look soft, like he was made of smoke.

"You’re tired," she noted. She could see a fine bead of sweat on his temple. The "feed" from their kiss had given him a surge, but the strain of masking two people from high-tech cameras and a supernatural tracker was clearly draining him.

Grayson leaned his head back against the elevator wall, closing his eyes for a brief second. "Exile is a thirsty state, Mailah. My abilities are a shallow well right now. But I will get you out of here."

"We," she corrected, stepping into his space. She didn’t care if the brothers were watching through the security feed. She reached up and wiped the sweat from his brow. "We are getting out of here."

Grayson’s eyes snapped open.

The intensity in them made her breath hitch.

He didn’t say anything, but he reached out and tucked a stray lock of hair behind her ear.

His touch was lingering, a silent promise that made the "shipping" energy in the room reach a boiling point.

The elevator dinged.

"Move!" Lucson’s voice barked through the earpiece. "He’s heading for the basement levels."

The doors opened to the loading dock. It was a cavernous space filled with wooden crates and the smell of diesel. At the far end, a massive rolling door was halfway open, revealing the rain-slicked pavement of the alleyway.

"Carson, status?" Grayson asked, his voice low and dangerous.

"Oh, you know, just being a hero," Carson’s voice chirped. "I’ve convinced the guards that a group of teenagers is currently spray-painting the front of the building with very offensive words. Valerius is distracted by the noise, but he’s heading your way. I suggest you move like the wind. Or at least like a very fast breeze."

They sprinted.

Mailah’s boots made soft thud-thud sounds on the concrete, muffled her suit. Grayson moved beside her, his movements fluid and silent.

Suddenly, the heavy door at the top of the loading ramp creaked open.

A man in a sharp, charcoal-grey suit stepped out. He didn’t look like a demon; he looked like a high-end lawyer, except for the way his nostrils flared as he inhaled.

This was Valerius.

"Hide," Grayson hissed.

He pulled Mailah behind a stack of crates marked Fragile: Egyptian Ceramics.

He pressed his body against hers, pinning her to the wood. The shadow-veil flared one last time, wrapping around them like a heavy blanket.

Mailah held her breath. Her face was pressed into the crook of Grayson’s neck. He smelled like cedar and cold rain.

She could feel his heart beating—fast, steady, and strong.

Valerius walked down the ramp. His footsteps were slow and deliberate.

Tap. Tap. Tap.

He stopped just three feet from their crate.

Mailah saw Grayson’s hand drift toward the dagger at his belt. His muscles were coiled like a spring.

If Valerius took one more step, the "undetectable" mission was going to turn into a bloodbath.

"Sir! You aren’t authorized to be in the loading bay!"

A sharp beam of light cut through the dusty air, splashing against Valerius’s expensive charcoal suit.

It was a museum security officer, a middle-aged man with a radio clucking on his shoulder. He looked frazzled, his cap slightly crooked from the "electrical fire" chaos Carson had caused in the other wing.

Valerius stopped in his tracks, his eyes narrowing as he turned toward the light.

For a split second, his face shifted—something predatory and ancient flashed in his gaze—before he smoothed it back into the mask of a cold, high-ranking official.

"I am with the private oversight committee," Valerius said, his voice dripping with icy disdain. "I was told to inspect the perimeter for security breaches."

The officer didn’t back down. He stepped closer, his heavy boots echoing on the concrete.

"I don’t care if you’re the donor himself, sir. We have a localized emergency. My men are evacuating the wing, and this area is a restricted zone during a Code Red. I need you to step back behind the line immediately."

Valerius tilted his head, his nostrils flaring as he took a deep, slow breath of the air.

He was ignoring the guard, his focus drifting back toward the crates where Mailah and Grayson were hidden. "I smell... something out of place. A scent that doesn’t belong in a garage."

"That would be the smoke from the faulty wiring," the officer snapped, clearly losing his patience.

He tapped his belt, his hand hovering near his pepper spray. "And as for things that don’t belong, that would be you. Now move, or I’ll have to escort you out. I don’t care how many ’committees’ you’re on; safety is safety."

Valerius stared at the officer for a long, tense minute.

The silence in the garage was so thick Mailah felt like she was suffocating.

Behind the crates, Grayson’s grip on her tightened, his body a solid, warm wall of protection.

He was ready to move the moment Valerius pushed past the guard.
