'So tell me, Dr Maxwell, if the whole of History lay before you ... where would you go? What would you like to witness?'

But one wrong move and History will fight back - to the death. And she soon discovers it's not just History she's fighting... 

Follow the tea-soaked disaster magnets of St Mary's as they rattle around History. Because wherever the historians go, chaos is sure to follow.
