A Symphony of Echoes by Jodi Taylor

Book Two in the madcap time-travel series based at the St Mary's Institute of Historical Research that seems to be everyone's cup of tea.

In the second book in the Chronicles of St Mary's series, Max and the team visit Victorian London in search of Jack the Ripper, witness the murder of Archbishop Thomas a Becket in Canterbury Cathedral, and discover that dodos make a grockling noise when eating cucumber sandwiches.

But they must also confront an enemy intent on destroying St Mary's - an enemy willing, if necessary, to destroy History itself to do it.
