A magnificent English detective story in the atmosphere of a mysterious and sinister boarding school. The tale of twin sisters who must unravel the secrets and riddles of their school.
Since the quiet, shy Rose came to our school, my sister and I have suffered with one question: who is she? What secret does this girl without a past keep—having only a golden locket from her previous life… and the ability to handle horses. And now we’ve been given a chance to solve this mystery: the whole school goes to a hotel by the lake! But it turns out Rose isn’t the only one keeping secrets. The dark waters of the lake are full of mysteries too. Someone comes out of it at night and wanders around the hotel, leaving wet footprints on the floor and frightening the guests. And in the evenings, if you look closely, you can see lights deep under the lake’s surface.
