As a child, he was told that dolls were for girls. On his daughter's birth, he vowed to make for her the prettiest doll in the world. Upon their return from the hospital, he sat down with his wife and explained his desire to make the prettiest doll in the world for their darling daughter. He told her that he knew of a place in a city far away from their bleak small town where they taught you how to make pretty dolls. If he left right away, he assured his wife that he'll be back in time for their daughter's first birthday with the prettiest doll in the world. Seeing her husband's enthusiasm, the wife reluctantly agreed and set about packing clothes and essentials for his long journey.

Next morning after cuddling with his baby girl and promising his wife that he'll return soon he set off on the trip to the far away city. A pal from work dropped him off by the highway. From there he would hitchhike his way to the bus stop to take the bus that would take him to the nearest city where he would board the train for his final destination.

On the highway, he met a fellow hitchhiker who happened to be a pretty doll with long hair and equally long legs caught his eye. Upon a quick assessment, he concluded that he liked her legs and would borrow them for use in making his daughter's doll. When he expressed the purpose of his trip, she was touched by the lengths he was willing to go (literally) to make the prettiest doll in the world for his daughter. The motorist dropped them a few miles before the bus stop and sped off.

After the motorist was out of sight, he borrowed this doll's legs and left her by the highway. In the same way, he borrowed a pair of graceful hands from a doll who sat beside him on the bus ride. By the time he had reached the city he had borrowed a torso, a slender neck, a head with the perfect round face, a pair of lips and a freckled nose from different dolls he met on his journey. Each time he borrowed from a pretty doll, he made it a point to explain the purpose of his trip to them.
Locating the place where they taught you the art of doll-making in the far away city proved to be more difficult than he had expected. When he found it, he was awed looking at some of the specimen dolls kept in large display cases. The only item that he was yet to acquire was a pair of eyes for his daughter's doll. As his training progressed, he was informed that if he intended to make the world's prettiest doll, then he would require years of practice and not mere months of training. Dejected though he was by his predicament he took to learning the art of doll-making with eagerness and absorbed all of the knowledge he would require in honing his craft. After training extensively for a couple of months, he left the city in time to reach his small town by their daughter's first birthday to fulfill the promise made to his wife.
Upon his return, his wife was relieved to see him happy and healthy. He told his wife about the skills he had learned in the distant city and how he would need to set up his workshop in the backyard shed to perfect the art of doll-making. So every day he would disappear for a few hours in the backyard shed to hone his skill.
One day when their daughter was about four years old his wife met with an accident.

The accident left his wife crippled and she would be bed-ridden for the rest of her life. The household chores were now his responsibility, he struck a fine balance between managing them and looking after his daughter & immobile wife. All the while he continued his practice of the art of doll-making.
On the daughter's eighteenth birthday she received a huge package with a card that read -
The prettiest doll in the world for my darling daughter. Happy birthday. Your loving father.
She opened the package with bubbling excitement for she would finally be able to see what her father had been working on all these years. The contents of the package paled her in shock and she let out a terrified scream. Panicked, she dashed out the back-door to the shed to look for her father. Even in her terrified state, she hesitated for a moment to open the door to the shed. It had been ingrained into her brain that the shed was off limits, only concern for her father's safety made her push open the door. She found him, rather his body in the middle of the shed with a note held in his hand, saying 'I will always watch over you through the eyes of your doll my angel.' Eyes darting around, searching for any signs of an intruder, the sight that greeted her made her blanch. She reached for her phone and made a frantic call.
When the police arrived, they found her in her mother's bedroom laughing hysterically. The bloodied knife in her hand suggested it's employment in meticulously carving out her now-dead mother's eyes. In between high-pitched laughs, she was humming in a sing-song voice -

Chubby cheeks, dimple chin
Rosy lips, teeth within
Curly hair, very fair
Oh! Daddy you forgot! She squealed.

Eyes are blue - not gray like you.
Mommy's pet, is that you?
Yes, Yes, Yes!

Fifteen months later the police concluded their country-wide investigation. In addition to unearthing the decomposing bodies of the seven women the father had murdered eighteen years ago, the police found at least a dozen mutilated remains of children in the shed. Contained in his notes they found meticulous diagrams illustrating the cryogenic procedures he had used to preserve the body parts he had collected. He had used the children for the purpose of practice before he created his magnum opus for his daughter. But nowhere did they find any clues that could lead them to the place where he had learnt how to make human dolls. They also discovered that he had orchestrated his wife's accident, so he could have better control over the house and ensure that nobody even accidentally entered the shed. The daughter is now confined to a state-run mental asylum having lost all rationality after having murdered her mother. And the neighborhood still reels in the shock-waves that the seemingly quite family had created.
