My twelve-year-old daughter fell asleep at school for the fourth Monday in a row after visiting her father, so I told her she wasn't going back that Friday.

Beth picked a small, nondescript diner three towns over, away from the prying eyes of our mutual acquaintances.

When she walked through the glass doors at 8:30 the next morning, I barely recognized her. Beth had always been radiant, with thick auburn hair and an easy, infectious laugh that had once made me feel a strange sense of relief that Derek had found someone genuinely warm to help raise Addie. But today, her scrubs hung loosely on her frame. Deep shadows ringed her hazel eyes, and her hair was pulled back into a hasty, messy knot.

She slid into the booth across from me, clutching a large paper coffee cup like a lifeline.

"Nina," she said, her voice strained. "Your text scared me. Is Addie okay? Did something happen between her and Derek?"

I looked at this woman. In another world, we might have been bitter enemies—the ex-wife and the new wife. But sitting across from each other in the dim light of a vinyl booth, we were just two mothers trying to keep our children alive.

"Addie is safe at home with my mother right now," I began carefully. "Beth, what I’m about to tell you is going to hurt. It is going to make you feel sick. But I need you to listen to everything before you react, because Molly’s life depends on it."

Beth’s hand froze around her coffee cup. The color drained from her face. "What are you talking about? Molly? What does Molly have to do with this?"

I didn't answer with words. Instead, I reached into my purse, pulled out the photocopies of Addie’s notebook pages, and laid them flat on the table between us.

Beth stared at the childish handwriting. Her eyes scanned the first entry.

*September 8th: Dad left at 7:45 PM. Molly cried for an hour...*

"What is this?" Beth whispered, her brow furrowing. "This is Addie’s handwriting."

"Read the rest," I said softly.

Beth looked down. As she read through the dates, the timestamps, the notes about front doors being locked from the inside, the burnt macaroni and cheese, and the nights Addie sat on the staircase clutching a wooden spoon because she heard noises in the backyard, Beth’s face transformed from confusion to sheer, unadulterated horror.

"No," Beth breathed, shaking her head violently. "No, this isn't real. Derek is with her. Every Friday night when I call on my midnight break, Derek answers! He whispers that Molly is asleep and that he doesn't want to wake her!"

"He forwards the house landline to his cell phone, Beth," I told her, my heart aching for the devastation in her eyes. "Addie confirmed it. Whenever you called, his cell would ring wherever he was. He’d step outside to take it, whisper to you that everything was quiet, and then hang up."

"Where... where does he go?" Beth’s voice broke into a ragged gasp.

"Addie doesn't know. All she knows is that he leaves around eight and comes back right before dawn, smelling of smoke and alcohol. And yesterday, when I told Addie she wasn't going back this weekend because she was collapsing from exhaustion at school, Addie had a full panic attack."

Tears spilled over Beth’s lashes, splashing down onto the photocopied paper. "Why? Why would she panic?"

"Because Derek told her," I said, leaning in, "that if Addie refused to come, he wasn't going to cancel his plans. He told a twelve-year-old girl that if she didn't show up to babysit, he would leave four-year-old Molly in that house completely alone all night."

Beth pressed both hands against her mouth, a muffled, strangled scream escaping her throat. She doubled over the table, her entire body shaking with violent tremors. Several patrons in nearby booths turned to look, but I didn't care.

I reached out and grabbed Beth’s wrists, holding her steady.

"Breathe, Beth. Look at me. Breathe."

"He left my baby," Beth choked out, gasping for air as tears poured down her cheeks. "He left my four-year-old baby alone in that house. What if there was an electrical fire? What if someone broke in? What kind of monster—"

"A monster who has been using my daughter to cover his tracks," I said, my voice hardening. "He pressured me for four consecutive weekends, Beth. He told me he wanted to 'reconnect' with Addie. He didn't want to reconnect with her. He wanted free, silent, captive childcare so he could disappear every weekend while you worked yourself to death at the hospital."

Beth straightened up, her expression morphing from shock into a terrifying, icy rage. The shattered nurse vanished, replaced by a mother whose maternal instincts had just been turned into a weapon.

"The charges on our joint account," Beth muttered, her voice dropping an octave. "The cash withdrawals. The downtown lounge charges. He told me he was investing in a commercial real estate flip with his college buddies."

"He’s gambling, isn't he?" I asked.

Beth looked up at me, her eyes hollow. "He had a problem ten years ago, before we met. He told me he’d been clean for eight years. He swore he never touched a card table again." She wiped her face with the back of her sleeve, her jaw setting like concrete. "I’m calling the police right now. I’m having him dragged out of that house in handcuffs."

"Wait," I urged, holding her arm. "If you confront him now without catching him in the act, he’ll claim Addie is lying, that she misunderstood, or that he only stepped out to grab milk for twenty minutes. We need him caught red-handed. We need him caught outside that house while Molly is inside."

Before Beth could answer, my phone buzzed violently against the table.

The caller ID displayed Derek’s name.

Beth and I locked eyes. The air in the booth turned subzero.

"Put it on speaker," Beth whispered coldly.

I tapped the screen and held the phone between us. "Hello, Derek."

"Nina," Derek’s voice came through the speaker, smooth, casual, and utterly devoid of remorse. "Hey, listen. I’m standing outside your house right now. Your mom is here, but she won't let me in. She says Addie is sick. What’s going on? Addie left her science project in my garage, and I wanted to drop it off."

I swallowed the bile rising in my throat. "She’s resting, Derek. She’s exhausted."

"Yeah, well, she needs to get used to a real schedule," Derek chuckled lightly, a sound that made my skin crawl. "Anyway, tell her I’ll pick her up Friday at three sharp. I’ve got big plans for us this weekend. We’re going to the water park on Saturday."

Beth closed her eyes, her fingernails digging so deeply into the diner table that her knuckles turned stark white.

"She’s not going this weekend, Derek," I said, keeping my voice utterly level. "I told you, she needs to catch up on her sleep."

There was a long pause on the other end. When Derek spoke again, the faux-jovial charm was entirely gone. His voice was flat, hard, and edged with menace.

"Nina, we have a legally binding custody agreement. Every other weekend, plus make-up time agreed upon in writing. If you don't have Addie on that porch at three o'clock on Friday, I’m calling the sheriff’s department and filing for immediate custody violation. And trust me, you don't want to play legal chicken with me."

Click.

The line went dead.

Beth looked up from the table, her eyes burning with a dangerous, lethal fire.
