Wherever the historians go, chaos is sure to follow...

Despatched to Victorian London to seek out Jack the Ripper, things go badly wrong when he finds the St Mary's historians first. Stalked through the fog-shrouded streets of Whitechapel, Max is soon running for her life. Again.

And that's just the start. Max finds herself in a race against time when an old enemy is intent on destroying St Mary's. An enemy willing, if necessary, to destroy History itself.

From the Hanging Gardens of Nineveh to the murder of Thomas a Becket, via an unscheduled dodo rescue mission, join the historians of St Mary's as they hurtle around History on more hilarious, hair-raising escapades.
