Eleanor and Izzy are on a trip to Newcastle, visiting the Literary and Philosophical Society library. They see odd shadows and hear ghostly whispering voices - and a book in a glass display case leafs open as they watch. Pages stop fluttering at woodcut of a group of witches hanged on the town moor in 1650. The girls hear a bell ringing and their adventure begins...The friends decide to study the witches for a history project. When witches' bones are unearthed in St. Andrew's graveyard in Newgate Street the girls investigate, and encounter an unearthly dark cloaked figure. As they follow the trail that the accused witches took around Newcastle, the friends fit the pieces of the puzzle together ...and put themselves in danger.
