Derby Gaol - S1.E14

Yvette and the rest of the Most Haunted team are locked inside Derby Gaol where in the late eighteenth century scenes of total incarceration and brutal executions took place. Jason sets a trigger trap of a wooden cross on a piece of paper in a reputedly haunted cell, which gives incredible results. Huddled in a cell later during a vigil, the whole crew smell roses although nobody knows where it's coming from... Filming later reveals the presence of orbs in the very same cell...
