Sarah, Rani and Clyde pay a visit to Ashen Hill Manor, reputedly the most haunted house in England. Professor Rivers and her somewhat smug assistant Toby have already set up shop in the house, looking for spikes in electromagnetic readings and other signs of paranormal activity. Despite Sarah’s reassurances that there are no such things as ghosts, strange things begin occurring almost immediately, including Rani’s sighting of Erasmus Darkening, an alchemist who supposedly conducted dark experiments in a lab beneath the manor in the 1600s. When Professor Rivers vanishes without a trace, even Sarah Jane has to admit that something strange is happening.
