Tony Robinson and the team head to Glendon Hall in Northamptonshire to unravel the mystery of the human skeletons found under an outbuilding. In November 2004 Martin Hipwell was working in the garden converting a Victorian brick shed. He had to stop rather suddenly because as he dug up the old floors he came across a whole host of human skeletons. He contacted the local unit, Northampton Archaeology, which revealed 11 burials inside one of the buildings.
