Whistling

"On the remote Scottish island of Skelthsea, Elspeth Swansome takes on a position as a nanny. Her charge, Mary, hasn't uttered a word since the sudden death of her twin, William - just days after their former nanny disappeared. But no one will speak of what happened to William. Just as no one can explain the lullabies sung in empty corridors. Nor the strange dolls that appear in abandoned rooms. Nor the faint whistling that comes in the night... As winter draws in, Elspeth finds herself increasingly trapped. But is this house haunted by the ghosts of the past? Or the secrets of the living?"--Publisher.
