In blind faith he has put himself and his daughter Emma at the mercy of his sister and her conniving husband, Caleb Crowther - for he has entrusted to them his entire fortune and the daughter he adores.

For Marlow and Emma, it is an impossible love - a love made in Heaven, but which could carry them both to Hell..."
