The Babysitter: My Summers with a Serial Killer

This chilling true story and “harrowing account of the evil that can lurk around the edges of girlhood” (Carolyn Murnick, author of The Hot One)—reminiscent of Ann Rule’s classic The Stranger Beside Me—follows a little girl longing for love who finds friendship with her charismatic babysitter, unaware that he is a vicious serial killer.

Growing up on Cape Cod in the 1960s, Liza Rodman was a lonely little girl. During the summers, while her mother worked days in a local motel and danced most nights in the Provincetown bars, her babysitter—the kind, handsome handyman at the motel where her mother worked—took her and her sister on adventures in his truck. He bought them popsicles and together, they visited his “secret garden” in the Truro woods. To Liza, he was one of the few kind, understanding, and safe adults in her life.

But there was one thing she didn’t know; their babysitter was a serial killer.

Though Tony Costa’s gruesome case made screaming headlines in 1969 and beyond, Liza never made the connection between her friendly babysitter and the infamous killer of numerous women, including four in Massachusetts, until decades later.

Haunted by nightmares and horrified by what she learned, Liza became obsessed with the case. Now, she and cowriter Jennifer Jordan reveal “a suspenseful portrayal of murderous madness in tandem with a child’s growing loneliness, neglect, and despair, a narrative collision that will haunt” (Sarah Weinman, author of The Real Lolita) you long after you finish it.
