The bedroom door swung open, and Mom hurried over to Aileen. "Ally, what happened?"

Aileen kept her head down. Blood seeped slowly through the gaps between her fingers, trailing down her entire arm.

She pulled her hand away from her forehead, revealing the wound where she'd struck herself. Her voice cracked with a sob.

"Mom, I just wanted to share the cake with Eudora, but she... she told me to get lost. She threw the cake on the floor and... and pushed me."

Mom's jaw tightened instantly.

She looked down at the frosting smeared across the floor, then glanced sideways at me, curled up in the corner by the table, not saying a word.

The sliver of concern on her face dissolved into fury. She raised her voice.

"Eudora!"

"Ally was kind enough to share her birthday cake with you, and this is how you act? Who exactly are you putting on that attitude for?"

I couldn't speak.

Beside her, Aileen suddenly shivered, as though startled, and slowly reached up to tug at the hem of Mom's sleeve. "Mom, my head feels so dizzy. Am I going to die?"

Mom pressed her hand to Aileen's forehead, her tone turning impossibly soft. "Ally, don't say such things! Today is your—"

She paused.

She glanced back at me, at my pale face, then turned back and spoke in a gentle murmur. "Ally, Mommy's taking you to the hospital right now. Everything's going to be fine."

Before leaving, she pulled a cash gift envelope from her purse and set it on the table.

She hesitated for a moment, then reached out and slipped a key into her own pocket.

"I'm taking the key. When you've learned to behave, you can go outside."

By the end of her sentence, her voice held nothing but impatience.

"And stop dressing like such a mess. People would think I'm abusing you."

The words barely left her lips before she steadied Aileen and walked out.

As she pulled the door shut, her hand paused on the handle. She seemed about to say something more to me.

But just as she opened her mouth, Aileen clutched her forehead, her body tilting backward.

"Mom, my head... it hurts so much. I don't think I can stand."

Mom's attention snapped back to her in an instant.

She wrapped an arm around Aileen, gently brushed the hair from her face, and examined the wound carefully.

"You're okay, Ally. Mommy already called 911. We're going to the hospital right now."

The door slammed shut with a bang, the overhead light swaying from the force.

The house was mine alone again.

The cake that had been knocked to the floor lay there just like me, dying in silence.

I followed them without a sound, watching as they climbed into the ambulance.

Mom patted Aileen's back, soothing her, her hands never stopping.

Aileen burrowed into Mom's arms, nuzzling her face against her chest, hair falling in messy strands across both cheeks.

One of the paramedics chuckled, a note of admiration in his voice.

"You two have such a wonderful bond!"

Mom smiled along and lifted a hand to rub the little head that had already tunneled beneath her collar.

Back at the house, a draft crept through the gap beneath the door. The candle flame flickered once, then went out.

I lay curled against the table leg, my body growing stiff.

At the hospital, Aileen had just finished getting her wound bandaged when something in her pocket stung her hand.

She pulled out the photograph and looked at it. Her pupils contracted sharply.

Her whole body slid down the wall until she was sitting on the floor.

Her eyes turned red in an instant, fat tears splashing against the tile.

Her lips trembled violently as she held the photograph out to Mom.

"Mom... Eudora, she... she shoved a photo at me."

"On the back it says if I ever dare call you 'Mom' again, she'll strangle me with a rope."

Mom's face darkened.

She snatched the photograph from Aileen's hand.

On the back, in handwriting I knew better than anyone, were the words.

That note was written by me while Aileen held a knife to my throat.

"Aileen, if you dare call her 'Mom' one more time, when you come home, I'll strangle you with a rope, chop you into pieces, and feed you to the dogs."

Mom kicked over the trash can beside her. Garbage spilled across the floor.

She dialed my number immediately, the vein at her temple throbbing.

One call after another. Every single one met with the same robotic voicemail prompt. Mom laughed from sheer fury, her chest heaving.

"Fine, Eudora. You've really grown bold!"

"You had the nerve to write something like this, and now you're pulling the silent treatment? Trying to make me feel guilty? Trying to make me worry?"

Beside her, Aileen tugged gently at her sleeve, her voice trembling.

"Mom, I'm so scared... She wouldn't really strangle me, would she? It's all my fault. Please don't blame her. Maybe... maybe I should just leave home. Once I'm gone, she'll calm down, and you won't be stuck in the middle anymore."

Mom looked at Aileen, cowering and self-sacrificing at her side, then glanced up at the strangers whispering around them.

All that remained in her heart was bottomless irritation and rage.

And in that moment, she made the decision that would jolt her awake in the middle of the night for the rest of her life.

"We're not going home tonight."

"She loves that house so much? Then let her stay in it by herself!"

She helped Aileen to her feet.

"We'll go to the Pinecrest Hot Springs Resort. If we leave now, we'll get there in time to celebrate your birthday. Let her sit at home and think about what she's done. Once she's come to her senses, we can talk about cutting ties for good."

She flicked on the turn signal. The car merged onto the highway heading out of the city, its taillights shrinking into the darkness, farther and farther from home.

In the house, only the ticking of the clock remained.

The phone that had been vibrating over and over was trapped beneath my body.

It buzzed against the hardwood floor, a muffled hum like some futile cry no one could hear.

The lit screen showed multiple missed calls from Mom.

The newest notification was a text message from her.

"Eudora, don't think sharing my blood gives you the right to do whatever you want. Ally is the only daughter I've ever truly claimed!"

"Stay home and reflect on what you've done. Don't you dare bother me while I'm celebrating Ally's birthday!"

In the days that followed, I did not bother them.

She assumed her threat had worked.

What she didn't know was this:

While she was soaking in hot springs and cutting birthday cake with Aileen, I was curled on the cold floor, slowly beginning to rot.

At the Pinecrest Hot Springs Resort, the air conditioning was set low, and beyond the windows stretched the vast open sea.

But Mom seemed distracted.

A strange tightness pressed against her chest, an unease she couldn't name, making it impossible to sit still.

She tapped her phone screen awake. Her finger drifted instinctively to the home security app, wanting to check on me, to see what I was doing.

But then she remembered that photograph covered in vicious words, and the text message I'd never answered. Her brow furrowed, and she shoved the phone back into her purse.

Aileen was a master at playing the victim.

To squeeze a little more sympathy out of Mom, she deliberately crashed into the pool wall while swimming that evening, leaving a sprawl of bruises across her shoulder.

"Mom, my shoulder hurts so bad. I can't move it."

Mom had no choice but to wrap an arm around her waist and walk her back to the room, one slow step at a time.

They passed a little boy holding both his parents' hands. He called out loudly, "That lady loves her big sister the most! Just like Mommy loves me the most!"

Mom's steps faltered. She forced a smile that didn't quite hold.

The next second, she corrected him almost on instinct. "Sweetie, the person a mother loves most will always be her own child."

The words left her mouth, and she froze where she stood.

She didn't even know how those words had slipped out.

Aileen leaned against her, and something dark flickered through her eyes when she heard it. But a second later, she was back to looking pitiful and helpless.

The next evening, Aileen suddenly burst into hysterical sobs.

She clutched her phone and stumbled over to Mom's side.

"Mom! Look at this! She's threatening me again!"

On the phone screen was a photo of Aileen's clothes, drenched in a dark, reddish-black liquid that looked like blood.

A note had been placed beside the clothes, scrawled in jagged, uneven handwriting:

"Stay away from my mom, or I'll dye your clothes red with your own blood!"

The message had been sent from an out-of-state number, though it was actually the phone of one of Aileen's admirers.

Mom stared at that vicious photo, then thought of how sweet and well-behaved I'd seemed the first time we met. Whatever hope she had left died completely.

"How did it come to this?"

She murmured it to herself, nothing but disappointment and confusion left in her eyes.

"My daughter was so good before. So obedient."

Late that night, Mom sat alone at the bar counter, smoking one cigarette after another.

Aileen came over carrying a glass of warm milk. She didn't say anything, just let the wound on her forehead show, as if by accident.

The raw, bloody gash made Mom lose the last of her composure.

She rubbed the bridge of her nose. "After your birthday party, I'm sending her away. She can't stay in this house anymore. She'll drive us all out of our minds."

She believed it was a fair decision for everyone.

And just as she finally allowed herself to breathe, a neighbor called.

"Is this Ms. Fox? Something reeks coming from your apartment. It's unbearable. We can't even open our windows!"

The neighbor's voice was urgent and furious. "We're all standing outside your door right now. You need to send someone over immediately!"

That smell was my body. It had been slowly decomposing since I died, the stench seeping from the living room out through the walls.

Mom was already irritated, still brooding over what to do with me. Her tone was dismissive.

"My daughter's home. She's got a temper, so don't go bothering her."

"It's probably just some takeout that went bad, or a dead mouse or something. I'll have the cleaning lady deal with it tomorrow."

After she hung up, the more she thought about it, the more it gnawed at her.

She opened our chat window and hammered out a message.

"Eudora! The neighbors are complaining about a smell. What the hell are you doing in there? I don't care what you think. You'd better have that place spotless by tomorrow!"

The message sent successfully. No reply came.

Her expression darkened. She tossed the phone aside.

But she would never know that the Eudora who used to keep the house clean had already died on her birthday.

Three days after the party, Mom drove Aileen back toward the apartment downtown.

Aileen draped herself over the back of her seat, working on Mom the whole ride.

"Mom, she's probably furious. She might not even let me through the door."

"Just promise me you won't lose your temper, okay? I'm not your real daughter anyway. It makes sense that she doesn't like me."

Mom said nothing. Her hands gripped the steering wheel, knuckles white, her face tight with displeasure.

The car pulled up to the building. Engine off.

She reached for the door handle and pushed it open.

In that instant, both of them froze.

The hallway was packed with people.

Two uniformed officers stood talking to the building manager. Beside them, a reporter hoisted a camera onto his shoulder.

But what seized their attention was the pair of figures in hazmat suits and respirator masks, carrying a stretcher out of my apartment.

Black liquid dripped from the stretcher onto the floor, and the stench rolled over them in waves.
