Sister’s betrayal

Chapter Two – The Unseen Lines

Amelia woke up before dawn, her body tense before her eyes even opened. The house was still too still. She turned to Derrick’s side of the bed, expecting the familiar weight beside her, but it was empty. The sheets were cool. He hadn’t come to bed at all.

She sat up slowly, pressing her hands to her forehead. It had become a routine: Derrick would leave the bedroom once she drifted off and pretend to fall asleep on the couch before morning. Some nights she heard his voice faintly in the living room low, careful tones as he whispered into his phone. When she confronted him, he’d simply say, “It’s work. Stop imagining things.”

But today, she didn’t want to imagine anymore. She needed to know.

Throwing on her robe, she stepped into the hallway. Light flickered from the kitchen. As she drew closer, the low murmur of voices grew clearer.

“…you shouldn’t be awake this early,” Derrick was saying.

Amelia froze. Her heart skipped a beat. She moved closer quietly until she could see them.

Melissa stood near the counter, wearing one of Amelia’s oversized T-shirts, her hair loose and messy from sleep. She smiled faintly at Derrick, her voice soft. “Couldn’t sleep,” she said. “Guess I’m still not used to this house.”

Derrick chuckled. “You’ll get used to it. It’s not so bad once you stop hearing the pipes moan every night.”

Their laughter felt like knives in Amelia’s chest.

She watched her husband reach for the sugar jar, brushing Melissa’s hand in the process. Neither of them pulled away quickly enough. It was a second just a second but Amelia saw the flicker of something dangerous in Melissa’s eyes. A warmth that shouldn’t be there.

She turned and walked back upstairs quietly before they noticed her. Her chest was tight, her throat dry.

She didn’t know what hurt more seeing the softness in Derrick’s face when he looked at Melissa, or realizing that he hadn’t looked at her that way in months.

Later that morning, Amelia sat at her desk in the office, trying to bury herself in work. Her boss, Mr. Craig Whitmore, had been unusually kind lately checking on her, asking if she was coping well. He was a strict man but respectful, the kind of boss everyone in the company secretly admired.

When he knocked gently on her office door, she straightened up.

“Amelia,” he said in his usual calm tone. “You look worn out. Everything alright at home?”

She smiled weakly. “Just… long nights. You know how it is.”

He studied her for a moment, then nodded. “If you ever need a few days off, take them. Don’t let work consume you.”

“Thank you, sir.”

After he left, she sat back and exhaled. Derrick would have laughed at that conversation, called it “inappropriate sympathy.” But she knew Craig meant well. He always did.

Her phone buzzed on the desk.

A message from Melissa.

Mel: “Hey sis, hope your day’s good. Derrick’s gone to the gym. I’ll make dinner tonight. You don’t need to stress.”

Amelia stared at the message for a long time, a strange unease curling in her stomach. Her sister’s tone was innocent, even thoughtful. But lately, everything that seemed innocent had begun to feel like a lie.

That evening, she arrived home earlier than expected. The smell of roasted chicken filled the air, and soft music played in the background. She could hear laughter again low and familiar.

When she walked into the dining room, Derrick and Melissa both turned. Melissa was wearing a fitted black dress Amelia had never seen before. The neckline dipped slightly, and her hair was styled perfectly.

Amelia smiled faintly, pretending she hadn’t noticed the awkward pause. “Dinner smells good,” she said, dropping her bag on the chair. “What’s the occasion?”

“Nothing,” Melissa said too quickly. “I just thought I’d make something nice.”

Derrick cleared his throat. “Yeah, she’s been amazing today. Even helped me fix that kitchen drawer you’ve been complaining about.”

“Oh, really?” Amelia’s voice held a careful calm. “How sweet.”

They sat down to eat, but the air was thick with tension. Derrick and Melissa exchanged glances every now and then, each one cutting Amelia deeper. She tried to engage in conversation, but the words kept dying on her tongue.

Halfway through the meal, Derrick’s phone buzzed. He picked it up immediately, a small smirk appearing on his lips. “Work,” he muttered before walking away to take the call.

The moment he left, Amelia looked up at her sister. “Melissa.”

Melissa froze, her fork halfway to her lips. “Yes?”

“Is there something I should know?”

The younger woman blinked. “What do you mean?”

“You and Derrick,” Amelia said slowly. “You’ve both been… different lately.”

Melissa dropped her gaze. “You’re imagining things, Amelia. He’s your husband. I’d never”

“I didn’t accuse you of anything,” Amelia cut in. “I just said things feel different.”

Melissa forced a nervous laugh. “You’re tired, sis. You’re working too hard.”

Amelia studied her face carefully, searching for cracks. But Melissa’s expression was smooth, almost rehearsed.

When Derrick returned, Amelia smiled politely and changed the subject. But in her heart, something had already begun to die a small flicker of trust that would never return.

That night, when Derrick slipped into bed beside her, she pretended to be asleep. She felt him reach for his phone under the pillow, the screen lighting up briefly before he turned away.

Her heart pounded. Slowly, she rolled to her side and peeked at his reflection in the mirror. He was typing, his face lit faintly by the glow. She caught a glimpse of the contact name on the screen

“M.”

A lump rose in her throat. She wanted to scream, to confront him, but her body felt frozen. Instead, she shut her eyes tightly and swallowed her pain.

Days turned into weeks. The tension grew unbearable. Amelia started noticing new patterns Derrick wearing cologne he hadn’t used in years, leaving home earlier, coming back late. Melissa, on the other hand, looked more radiant every day. She hummed as she moved around the house, her phone constantly in her hand, her lips always curled in a secret smile.

One Saturday morning, Amelia woke up and found Melissa gone. Her suitcase was missing too. Panic gripped her chest. When she asked Derrick, he looked at her with a strange calm.

“She said she needed space,” he said. “Said it’s time she moved on from Dean and… from staying here.”

Amelia stared at him. His tone was detached, almost rehearsed.

She forced a smile. “That’s good. She deserves a new start.”

But deep inside, she knew this wasn’t the end. No, this was just the beginning of something darker something twisted enough to make the betrayal feel like mercy compared to what was coming.

Three days later, Amelia got a message on her phone. No name, just a video file. Her fingers trembled as she opened it.

The first few seconds were blurry, but then she saw it clearly

Derrick. In a hotel room. With Melissa.

And in the corner of the screen, the date glowed like a cruel reminder just two nights before Melissa left the house.

Her body went cold. Her vision blurred. She could barely breathe.

In that moment, Amelia didn’t cry.

She didn’t scream.

She only whispered one thing under her breath something sharp, broken, and full of quiet rage:

“They think they’ve won.”
