The team first visited the location during series 12 of the show back in 2008.  Meanwhile, Stuart tackled a location with a nautical twist as they climb aboard the SS Great Britain in Bristol. Today the ship is a museum and one of the city's most popular tourist attractions, but during its 41 years of service it spent its time shipping passengers between Bristol and New York. After an investigation on the ship in 2009, Yvette described the SS Great Britain as one of the top five most haunted places the team had ever visited. But a much scarier and disorientating location awaits Glen.
