It’s been a while since the Mystery Busters’ last adventure, and Becky’s friend Helayna has found herself temporarily relocated to a village close to White Horse Hill in Oxfordshire. She’s feeling sad and so her mother invites her faithful friends round for a sleepover.Venturing out on their bikes that evening, the children settle on the edge of a field where Alex, after researching the area, makes up a spooky story about long-lost highwaymen, and an underworld dominated by witches and a terrifying Saxon warlord from centuries past.Unsettled but determined, the next day the friends bike up to Waylands Smithy to explore the ancient site. Suddenly they feel the ground start to vibrate and with a crash of thunder and the sound of galloping hooves, a huge dark horse rider is seen fast approaching across the fields wielding an axe! They flee to the woods to escape only for the ground to collapse beneath their feet, plunging them into a scary underground abyss, where they find themselves caught up in another mystifying adventure.Is Alex’s story coming true? If it is, then the children must escape this place before daybreak or risk being trapped there forever.In this riveting tale the Mystery Busters encounter another frightening array of adversaries, but also benevolent beings in a story full of fantasy, adventure, peril and courage.
