door before we got to it, as if she had been waiting behind the curtain.

She scooped Ruby into a hug and told her she’d grown an inch since the last visit.

My father took our overnight bags and said dinner was nearly ready.

For thirty seconds, I let myself believe I had been unfair on the drive.

For thirty seconds, I thought maybe everyone could just behave.

Ruby heard the word dinner and took off for the kitchen.

My mother laughed and called after her that she’d stocked up on all her favorites.

When I followed, the refrigerator was already open, and Ruby had found a plate on the middle shelf with a thick slice of chocolate cake, dark frosting, and raspberry filling between the layers.

She turned with it balanced carefully in both hands.

‘Can I have this?’

My mother was standing in the doorway.

She looked at the cake, then at Ruby, and waved her hand.

‘Of course, sweetheart.

Go ahead.’

That was it.

No hesitation.

No warning.

No, not that one.

Ruby sat at the table and ate with the solemn joy children bring to dessert.

She licked frosting from the side of her finger and grinned at me with chocolate on her lip.

I remember thinking she looked impossibly small in that kitchen chair, her legs swinging, the yellow dress she’d chosen because Grandma always told her yellow was her color spilling over the edges of the seat.

Twenty minutes later, a car door slammed outside hard enough to shake the glass in the back door.

Vanessa came in already angry.

She was talking before she cleared the hallway, complaining about traffic, rude customers, everybody expecting too much from her.

My mother started one of those bright, smoothing little sentences meant to soften the air.

Vanessa ignored it, walked straight to the refrigerator, opened it, and went still.

Then she turned and shouted, ‘Who ate my slice?’

Ruby froze.

Her fork hovered halfway to her mouth.

She looked toward me first, then toward Vanessa, confused but not yet afraid.

Vanessa looked at the plate.

She looked at the frosting on Ruby’s lip.

And then something in her face changed so quickly it was like watching a door slam shut.

‘You little thief.’

I was already pushing away from the counter.

I had taken maybe two steps when Vanessa crossed the kitchen in three of her own, grabbed Ruby by the hair, and drove her face into the edge of the table.

The plate shattered as it fell.

Ruby’s body went slack with a speed that still turns my stomach.

Blood started running down her face, bright and shocking against that yellow fabric.

One second she had been blinking up at us with cake on her mouth.

The next she was unconscious in a collapsing chair.

I lunged, and my mother caught me.

Not to help.

Not to steady me.

To stop me.

She pinned me back and hissed, ‘Don’t go near her.

Let your sister calm down.’

My father came in a beat later and grabbed my arms as if he had stepped into an argument instead of a crime scene.

‘You’re overreacting,’ he said.

‘Vanessa barely touched her.

Kids get dramatic.’

Ruby was not moving.

I got one hand loose, snatched my phone off
