While most people assume seventeen-year-old Lenora was responsible, the police were never able to prove it. Other than her denial after the killings, she has never spoken publicly about that night, nor has she set foot outside Hope?s End, the cliffside mansion where the massacre occurred.Stabbed her father with a knifeTook her mother?s happy lifeIt?s now 1983, and home-health aide Kit McDeere arrives at a decaying Hope?s End to care for Lenora after her previous nurse fled in the middle of the night. In her seventies and confined to a wheelchair, Lenora was rendered mute by a series of strokes and can only communicate with Kit by tapping out sentences on an old typewriter. One night, Lenora uses it to make a tantalizing offer?I want to tell you everything.?It wasn?t me,?

But when new details about her predecessor?s departure come to light, Kit starts to suspect Lenora might not be telling the complete truth?and that the seemingly harmless woman in her care could be far more dangerous than she first thought.
