The Fire on Slate Fell

After a frightening encounter with a cigar-chomping biker gang, young sisters Mae and Isla Donaldson investigate a mysterious fire that has left no trace. The mystery deepens when a beautiful visitor speaks of buried treasure and a hooded stranger is overheard bragging in the local pub. Curiosity turns to terror when Isla disappears on the trail of clues left by a fell-walking eccentric, who has also vanished. Mae's powers of deduction and Isla's emotional insight are stretched to the limit by an audacious fraud.
