Caroline couldn't sleep. She was much too excited. Ever since she turned seven, Christmas had ceased being special for her.
But this year...this year was different.
It began when she saw the doll through the window of the toy shop on 22nd Street. Her mother had been pulling her along to some appointment or something when the perfect porcelain face caught her eye. Caroline stopped abruptly, staring at the flawless doll with wondering eleven-year-old eyes. The doll smiled back at her, its red cardigan bright against the shabbiness of the shop. She knew she had to have it. Just then, her mother got impatient and pulled her along, scolding her for dawdling. Caroline didn't care; she was already composing her letter to Santa in her head.
The minute they got home, she sat down at the table and wrote to Santa in her very best handwriting. She signed it with her very best cursive and mailed it, taking care to address it correctly.
Throughout the rest of the week, Caroline went back to gaze at the doll. After three days of ogling it, she noticed a white "C" embroidered on the doll's collar. C for Caroline, she thought happily. The doll was meant for her.
The next day, she noticed the doll's hair looked quite like her own. In fact, it looked exactly like her own; long, straight, and dark. It just made her want the doll more. We're like twins!
By the end of the week, Caroline had discovered that the doll looked exactly like her. Everything, even the freckle on her cheek, was identical. It must have slipped her mind before that the collar said "Caroline," because her name was definitely embroidered there. She'd always wanted a twin; now she'd be able to brag to her friends about her lovely doll that looked just like her.
Her mother, Abbey, had started to get spooked by the doll that her daughter so desperately wanted. Despite the fact that she rushed Caroline along to her dentist appointment, she actually took a good look at the doll. She could have sworn that its collar didn't say anything...and wasn't it blonde before? Each day she came back with Caroline to look at it, she got more anxious. Was somebody stalking her daughter and changing the doll accordingly? It didn't seem unlikely. So she didn't buy the doll, even though she knew how much Caroline wanted it. The doll Abbey got for her daughter wasn't quite as dainty as the one in the shop window, but it vaguely resembled Caroline and she hoped it would be enough.
Christmas morning, Caroline ran full tilt downstairs and attacked the largest package. She ripped the wrapping off and squealed in delight. Her mother smiled, glad she liked the gift even if it wasn't exactly what she wanted. But as Caroline picked the doll up out of its wrapping, her smile faded.
A perfect copy of Caroline was staring from over her daughter's shoulder.
I actually wrote this for a writing audition, so that's why it's short. My first attempt at anything remotely creepy or disturbing, so please review and tell me how I did.
