There was something wrong with her.

I could tell from the beginning. It wasn’t how she looked, although it more than offered to my imagination. Shoulder-length black hair. White skin. It was always the dark ones, she told me once. I believed her.

It’s easy to recall the day she came to us. Take care of her, Mother had said. She’s fragile. And then she’d put her in my arms, this new pink-skinned baby, and I looked into her little baby-black eyes and wanted to kill her. I put my hand on the paperweight at the desk, but Mother was looking, so I set it down and gave her back.

She never looked at the mobiles hanging above her crib. They were bright shiny things, with pink ponies and light blue bunnies that twirled even without a draft. Mother hung toys from the wooden slats that even glowed when it was nighttime. Mother said she wouldn’t feel scared that way when it became dark.

Her eyes would roll and she’d look over at me. Babies can’t turn their eyes like that, I’ve heard, or smile, but she looked over at me and she smiled.

It was worse when she first crawled. She took a liking to me at the instant, came to my feet while I sat in the rocking chair, her hair a puffy black cloud around her face. She opened her mouth, and she had two sharp little teeth. I didn’t pick her up, and she never cried.

She became as quiet a toddler as she was a baby. Mother dressed her in fluffy pink skirts with white trim that made her pale skin look even paler. I sat her in the sand box in our back yard, and she didn’t touch the hot sand, but looked up at the sun unblinkingly. I stayed behind in the shade, looking at her while she looked at the sun. I wanted her delicate skin to burn. I wanted to watch it turn red and crisp and boil.

Mother was out at the store the entire day through, and she was in the sand box the entire day through. Before Mother came home, picked her back up, and took her inside. Her skin wasn’t even warm.

I watched her as she grew. I always liked children, but I never liked her, and when I held her I wanted to put one hand on her small chin and another on the back of her head and twist hard enough to hear the snap. Later, I thought, because she was too small now and there was still time.

It wasn’t long before she dressed herself. As soon as she got tall enough and strong enough to slide open the drawers on her dresser, she clothed herself, and as soon as Mother started forcing me to take her clothes shopping, she wore black. She was partial to black, and red, but she never touched anything gold. For her birthdays I got her a little necklace, bright pure gold, and I put it on her. She screamed, and with her short nails clawed at her throat and Mother made me take it off.

She still liked me. She sat on my lap when I read during the day, and knelt by the computer when I tried to ignore her, her large dark eyes just staring at me. Staring.

She didn’t go to school, nor did she learn from Mother. She taught herself, reading what Mother told her to read and writing what Mother told her to write, but her real education came from her own self. I found the first one when she was seven, a little mockingbird pinned to the bark of a tree with her sharp, ruby-decorated hairpins. Blood ran down its feathers, spread out and dried like some sick stigmata. It was still twitching when I took it down, but there was nothing for it now. I held it like I held her, and watched the blood flow over my hands until it finally stopped moving. I buried it under her childhood sandbox.

She sat by me at dinner that night, Mother’s lasagna on the table while Mother herself chattered away about neighborhood gossip. Her eyes stayed on me, and she smiled again, like she had when she was a baby. Her teeth were white and even now, though, and her lips a dark red. It looked like the blood of the jay.

But later, I knew. I’d have time to kill her later, to pin her hands to the trees and slit her throat quickly. She would not suffer, as the bird had, but I’d wait until she was bled dry from her hands before the actual cutting, and then I would bury her somewhere under the moon she admired so much. Her pale dark eyes would close, and she would never look at me again.

She grew curves, her breasts before her hips, and her cheeks hollowed out. Her dark eyes grew darker, her black hair blacker, and still she loved me. I found the cat under my bedroom window, stomach slit open from its genitalia to its chin, and its innards spread artfully around it. They were concentric circles, perfect and bloody.

Boys asked her out. Girls asked her out. She never said yes, and she spent her nights with me, while I watched the television, while I cooked and ate dinner, while I did homework. She didn’t often speak, but she always talked to me. I saw the words in her eyes and her movements.

She finally grew to the age I’d been when I’d first found the bird, and Mother was dead. The police didn’t know what happened to her, although there’d been much investigation, but I knew.

It would be too late. I realized this now, looking at her long legs and slim waist and strong arms. She could match me, so I’d have to do what I had to do while she slept.

I went into her room, where she always slept on her back, her round, bare breasts reflecting the moonlight from the window. She didn’t look vulnerable, even now, but she was more so than before.

She didn’t wake when I took the paring knife and the nails from the kitchen. She didn’t wake when I straddled her hips, looking down at her blank face. Her black hair was in soft rings around her head, like the cat’s guts, and I knew I was going to slit her like she’d done the cat, and crucified her like the bird, and I’d keep my hand over her mouth as she floundered and died.

She woke when I nailed her palms to her bedside table and her bedpost. Her eyes were wide, afraid, but I just shh-ed her calmly and put my hand over her mouth. She tried to bite me when I shifted, and then I smoothed her sweaty brow.

It’s for the best, I told her.

She shook her head. No.

I slid the knife from her girl’s parts, where she was blossoming well and her black hair was curly, up her gut and stomach and chest. I had to press harder on her chest, but it came. Her eyes were open, but she didn’t shake her head or try to fight at all anymore. Blood was pooled everywhere, drying on her hands.

Like the jay. I could see the way she had done it, holding it lovingly while she tacked it down. Or the cat, spreading out its stomach and intestines in the flower bush. I could even see how Mother had died, in the home where we’d put her because she was old. Their trees would blossom well this season, I knew, because she would keep giving the gift she’d given her and me. They would flourish as we had.

It’s for the best, I wanted to tell her. But now she was gone.

There was something wrong with her.
