Thereโs only a handful of mediums worldwide who claim to do anything close to what Helen Duncan said she could and physically manifest spirits into a room. For Sian, the only way to fully understand what was happening at Helenโs sรฉances is to witness this for herself, so she tracks one of these rare mediums down in the Netherlands. Sian arrives at the Dutch monastery and is greeted by a host who takes Sian on a private tour of the sรฉance room, where the medium will work that evening. The traditions havenโt changed much since Helenโs 1930s sรฉances. The medium will be searched, then tied to a chair, enclosed behind a black curtain, and spirits, depending on what unfolds that night, may physically 'appear'. The room will be pitch black, and Sian will be locked inside.
