A year abroad for Czech brother and sister Jan and Marie means arriving in rural England in the middle of the night - and not everyone is welcoming. As they try and settle into their new school, they are plunged into a series of mysteries. Who is the battered old lady in the tattered clothes? Why is their new landlord such a nasty piece of work? What is the real story of the ghostly Roaring Bull - and what lies hidden in the local church?

Old legends are revived as Jan and Mari unearth shady secrets in a desperate bid to save their family from eviction. In their quest, they find unlikely allies and deadly enemies - enemies who will stop at nothing to keep the past buried.
