Ok pretty obscure so a wee clue, writen by the same author who wrote the short story 'The Quiet Man' later turned into a movie with John Wayne and Mary? O'Hara (not 100% on the female actress here and refuse to google answer
)
No Googling either guys.
Another wee clue is the story was centered on Tirriemore Farm Cottage and a big fat clue is what you use to lock the door and where that lock usually is....... giving it away now.
