The Billionaire Who Came Back For His Baby

CHAPTER 4: "The Number Was Fake"

Leo stood frozen in the hallway, phone still pressed to his ear even though the line was dead. The elevator doors opened beside him with a soft hum, but he didn’t move. His jaw was locked so tight it ached. The voice kept replaying in his head: You found them.

The apartment door creaked wider. Mia stepped into the hall and gripped the frame like it was holding her up. Her face was pale. The fear in her eyes wasn’t new; it was the kind that came from years of protecting Liam alone.

“Who was that?” Her voice was low. She kept it quiet so it wouldn’t carry to the living room.

Leo lowered the phone and stared at the blank screen. “I don’t know.”

Their eyes met across the narrow hallway. For the first time since yesterday, the full weight of it hit them. This wasn’t just about a lie from five years ago. Someone had planned their separation. And now that same person was watching.

Mia’s breath caught. “Leo…”

“I’m not leaving you like this,” he said, voice rough. But he knew he had to. Pushing tonight would only scare Liam.

He didn’t want to leave.

He stood at the door for a long minute, talking quietly while Liam’s spaceship sounds drifted from the living room. “I can stay on the couch. Or downstairs. I don’t like this.”

Mia shook her head, arms wrapped around herself. “It’s too much too fast. For him. For us.” Her eyes flicked to the living room window with the broken latch. “But that call scared me.”

The fear in her face decided it. Leo stepped back, every instinct telling him to stay. “Lock everything. Deadbolt, chain, windows. I’ll have someone watching the building tonight. Discreetly.”

Mia nodded, shoulders still tense. She waited until the elevator closed before turning the deadbolt with a heavy click. Then she slid the chain in and checked every window twice. She taped the broken latch and wedged a chair under it. The apartment felt smaller than it had that morning.

She was making Liam’s lunch when her phone buzzed on the counter. The sound made her jump.

*Unknown number:*

Be careful who you trust.

Her stomach dropped. She read it twice, then deleted it and blocked the number. But the words stayed. Who was doing this? And why now, after five years?

She leaned against the counter and closed her eyes. Liam was laughing in the other room. She couldn’t fall apart tonight.

Leo couldn’t sleep.

The penthouse felt too big and too empty. He sat on the edge of his bed in the dark with city lights behind him. In his hand was a photo he’d taken earlier of Liam’s spaceship on the coffee table, sunlight on the plastic. He zoomed in until he could see Liam’s fingerprints on the wings.

His chest hurt.

Then he started making calls.

Maria, his old assistant, picked up on the second ring. “Mr. Voss? Is everything alright?”

“I need everything from five years ago,” Leo said. “The hotel, the event, the agency. Every record, every email, every log.”

His security chief got the same call. Then a PI who owed him. “Wake people up if you have to,” Leo told them. “I want answers by morning. Someone played with my life. With my family.”

He paced until dawn. The photo of the spaceship was still open on his phone.

The next morning, Liam bounced into the kitchen in his spaceship pajamas. His hair was everywhere.

“Is Leo coming today?” he asked, eyes bright.

Mia paused with the milk jug in her hand. The hope in his voice scared her more than the texts. Three days ago Leo was a stranger. Now Liam lit up at his name. If this went wrong, it would break him.

“He said he would,” she said carefully. “But we’ll see, okay? Don’t get too excited.”

Liam grinned anyway. “He’s really good at Legos. And he listens when I talk about rockets.”

Mia ruffled his hair and tried not to think about all the mornings she’d done this alone.

Leo arrived at eleven exactly. The second the door opened, Liam launched himself at him and wrapped around his legs.

Leo laughed and picked him up. “Hey, buddy. Missed me?”

“Yeah!” Liam started talking a mile a minute about his morning.

Mia watched from the kitchen. She’d never seen Liam attach this fast. Not even to her mom. Seeing Leo hold him so naturally stirred something dangerous in her. Longing. Fear. Hope.

They went to the science museum. It was Liam’s idea, and he didn’t stop talking about planets and rockets the whole car ride. Leo listened like every word mattered and asked questions that made Liam glow. During the planetarium show, Leo looked over at Mia in the dark. Something passed between them. Years of what-ifs. Then they both looked away.

The afternoon was full of small moments. Leo explaining gravity while Liam hung on his words. Mia watching them with a lump in her throat.

Later in the park, Liam ran ahead with a melting ice cream cone. Chocolate dripped down his wrist.

An older woman on a bench smiled at them. “You’ve got a lovely little boy,” she said, looking at all three of them.

Leo looked at Mia.

Mia looked at Leo.

Neither corrected her.

The moment hung there. Your son. Like it was normal. Like five years hadn’t been stolen.

“Thank you,” Leo said quietly.

The woman went back to her book. Liam kept running, shouting about Mars.

Mia swallowed against the burn in her eyes. Leo’s hand brushed hers for half a second as they walked. Neither spoke, but the silence was full.

That evening, after Liam crashed on the couch, Leo stayed.

They sat at the kitchen table again. The same one where everything broke two days ago. The city hummed outside.

“The number was a burner,” Leo said, sliding his phone over. “Impossible to trace. But my investigator found something else.”

Mia waited, stomach tight.

“Five years ago, someone accessed my hotel booking records,” he said. “They asked specifically about the woman I left the event with. They knew your name. They knew where you were placed.”

Her breath caught. “So it wasn’t random. Someone planned this.”

“No.” His voice was hard. “It was targeted. They wanted us apart.”

Her phone sat face-down between them. She still hadn’t told him about the text. Maybe later.

Leo’s phone rang and cut through the silence.

He answered right away. “What do you have?”

Mia watched his face change. His back straightened.

“I found the employee who pulled those records,” the investigator said through the speaker.

Leo’s grip tightened until his knuckles went white. “Who was it?”

There was a long pause.

“That’s the strange part,” the investigator said. “The request didn’t come from hotel staff.”

Leo’s eyes met Mia’s across the table.

“Then who?” he demanded.

“It came from someone inside your company.”
