For the first six days of William Waters’s life, he was not an only child. He had a three-year-old sister, a redhead named Caroline. There were silent home movies of Caroline in which William’s father looked like he was laughing, a sight William never saw again. His father’s face looked open, and the tiny redhead, who pulled her dress over her face and ran in giggling circles in one of the movies, was apparently the reason. Caroline developed a fever and a cough while William and his mother were in the hospital after his birth. When they came home, the little girl seemed to be on the mend, but the cough was still bad, and when her parents went into her room to get her one morning, they found her dead in her crib.

William’s parents never mentioned Caroline while William was growing up. There was one photograph of her on the end table in the living room, which William traveled to occasionally in order to convince himself that he’d actually had a sister. The family moved to a navy-shingled house on the other side of Newton—a suburb of Boston—and in that house, William was an only child. His father was an accountant who worked long hours downtown. With his daughter gone, the man’s face never opened again. William’s mother smoked cigarettes and drank bourbon in the living room, sometimes alone and sometimes with a female neighbor. She had a collection of ruffled aprons that she wore while preparing meals, and she became agitated whenever one became stained or messy.

“Maybe you shouldn’t wear the aprons while you cook,” William said once, when his mother was red-faced and on the verge of tears over a dark blotch of gravy on the fabric. “You could tuck a dish towel in your belt instead, like Mrs. Kornet does.”

His mother looked at him as if he’d spoken in Greek. William said, “Mrs. Kornet, who lives next door? Her dish towel?”
