In the lounge of the Lincolnshire Aviator pub, situated deep in the heart of the Lincolnshire Wolds in England, just over a mile and a half down the road from the old air base, some locals were in deep conversation about the expected arrival from London of an American couple. The couple were expected to arrive that very evening, and due to an unfortunate overheard remark by the landlord of the pub, Jack Hastings, to his wife, Jean, gossiping and speculation were now rife in the lounge and public bars about the reason for the Americans' visit. Jack had been talking casually about the reasons for the couple's visit to Jean, saying the couple was more than just a little bit interested in the old air base down the road and that a relative of theirs flew from the base with The Pathfinders during the Second World War. That chat between Jack and Jean Hastings, overheard by one of the locals, led to gossip amongst the regulars and the speculation that the Americans were CIA agents after some dark secret. In fact, the truth was far more terrifying than the speculation in the pub. A few days later four other visitors arrived at the pub. They were the newly formed Paranormal Investigation Project, and under their investigation the horrifying truth began to emerge.
