It's Halloween 1992 and The BBC are about to create a legitimate piece of television history.
At 9:25pm they air Ghost Watch, a mockumentary which tells the story of a ghost called Pipes and the family home he haunts.
It has Michael Parkinson, Sarah Greene and Craig Charles hosting the 'live' show - three of TV's most trusted faces - and over the next hour and a half viewers, many unaware of the show being a drama, are taken into an event that becomes so scary that the BBC will face more complaints that ever before and the show will go down in infamy, disowned for ten years and never aired again.
This is Ghost Watch, a piece of Halloween history and tonight Marc chats to Stephen Volk, the writer of this unforgettable piece of history.
Stick on the kettle, power up the proton pack, put a circle of salt around you to warn of evil spirits and relax.
Oh, and Happy Halloween...
