If you can hear it, it's already too late . . .
Alone in the world, Elspeth Swansome takes the position of nanny to a family on the remote Scottish island of Skelthsea. Her charge, Mary, hasn't uttered a word since the sudden death of her twin, William—just days after their former nanny disappeared. No one will speak of what happened to William. Just as no one can explain the hypnotic lullabies sung in empty corridors. Or the strange dolls that appear in abandoned rooms. Or the faint whistling that comes in the night . . .
As winter draws in and passage to the mainland becomes impossible, Elspeth finds herself trapped. But is this house haunted by the ghosts of the past? Or the secrets of the living?
