This week, we're helping out our good friend Giselle on her archaeological dig at Cherwell Castle - oh, and solving a murder from 700 years ago, obvs! Highlights include:- Real life documents from the 1300s!- Here's the evidence, off you go!- Jane knows actual Latin...- Lambert Harcourt, what a lad...- You were always saying you wanted some Gregorian chanting, right?- Giselle can't remember her password, silly bitch...- Are you Henry Graves?- Ingrid needs to get her dates right...- Paul Robinson takes a day off from Lasseters to help us out...- Maybe the whole thing was God all along...- But what was the head wound from?- There's SO MUCH PAPER!- We pass it on to Jane's mum...- Name a type of person and there's one of these where they've died...- You're not taking this on the train...
