This is not mine I read it many years ago & could never find it again, so this is basically what it was about.
A young couple bought a run down house to do up & live in, it was large & old. They were told by the villagers it was haunted, but that didn’t put them off.
The ghost was a little boy called Billy & he’d run in the back kitchen door, up the stairs to the master bedroom then vanish.
This happened every day at 3 p.m. for weeks, the house owners got used to him & the wife even spoke to him as he ran passed her & he’d chuckle in reply.
Then one day during the renovations the wife was in the kitchen as the boy ran in, instead of letting him go she tried to stop him, managed to get passed him on the stairs & into the master bedroom, saying to him, ‘No Billy, not safe, the balcony railing has been removed from the balcony & you will fall’. She held her arms out & for the first time she could see him & touch him, then a big smile came over his face & he shone, then vanished.
He had died falling from that balcony all those years before, he was waiting for someone to save him.
