House Rules by Jodi Picoult

winter night in 2006, she went out drinking with her friends, eventually splitting from them and heading to SoHo, where she called a friend to say she was at a bar. She never returned home. Instead, her naked body was found fourteen miles away, in a deserted area off the Belt Parkway in Brooklyn, wrapped in a flowered bedspread. Her hair had been cut off on one side, her hands and feet were secured with plastic ties, she‘d been gagged with a sock, and her face was wrapped in packaging tape. She had been raped, sodomized, and suffocated.
    Blood was found on one of those plastic ties, but DNA evidence revealed that it didn‘t belong to the victim. Instead, it was matched to Darryl Littlejohn, a bouncer who had been asked to remove the drunk young woman from the bar at around 4:00A.M.Witnesses said they argued before leaving the bar.
    Fibers were also found in Littlejohn‘s residence that matched those on the packing tape on the victim‘s body.
    Littlejohn was also arraigned for a second kidnapping and assault of another college student who managed to get away from him after he impersonated a police officer, handcuffed her, and threw her into his van.
    And Imette St. Guillen, tragically, went from being a student of criminal justice to being the lesson taught by professors of forensic DNA analysis.

    I used to have friends. Back before I had children, when I was working at a textbook publishing company outside of Boston, I‘d hang out with some of the other editors after hours. We‘d go for sushi, or to see a movie. When I met Henry he was a technical consultant on a computer programming textbook my friends were the ones who encouraged me to ask him on a date, since he seemed too shy to ask me. They leaned over my cubicle, laughing, asking if he had a Superman side underneath all that Clark Kent. And when Henry and I got married, they were bridesmaids.
    Then I got pregnant, and suddenly the people I could relate to were enrolled in my birthing class, practicing their breathing and talking about the best deals on Diaper Genies. After we had our babies, three of the other mothers and I formed a casual playgroup. We rotated hosting duties. The adults would sit on the couch and gossip while the babies rolled around on the floor with a collection of toys.
    Our children got older and started to play with each other instead of beside each other. All of them, that is, except Jacob. My friends‘ boys zoomed Matchbox cars all over the carpet, but Jacob lined them up with military precision, bumper to bumper. While the other kids colored outside the lines, Jacob drew neat little blocks in a perfect rainbow spectrum.
    I didn‘t notice, at first, when my friends forgot to mention at whose house the next playgroup was taking place. I didn‘t read between the lines when I hosted and two of the mothers begged off because of previous engagements. But that afternoon, Jacob got frustrated when my friend‘s daughter reached for the truck whose wheels he was spinning, and he hit her so hard that she fell against the edge of the coffee table. I can‘t do this anymore, my friend said, gathering up her shrieking child. I‘m sorry, Emma.
    But it was an accident! Jacob didn‘t understand what he was doing!
    She stared at me. Do you ?
    After that, I didn‘t really have friends anymore. Who had time, with all the early intervention specialists that were occupying every minute of Jacob‘s life? I spent the entire day on the carpet with him, forcing him to interact, and at night I stayed up reading the latest books about autism research as if I might find a solution that even the experts couldn‘t. Eventually, I met families at Theo‘s preschool who were welcoming at first but distanced themselves when they met Theo‘s older brother; when they invited us for dinner and all I could talk about was how a cream of transdermal glutathione had helped some autistic kids, who couldn‘t produce enough of the substance themselves to bind to
