The Babysitter: My Summers with 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.
