Hi Simon! I pretty much agree with AndyJ's comment - I don't understand how there can be a ghost, if the old woman is still alive? If she has supernatural powers and is able to "punish" the two thieves in this fashion, I think you have to explain or set it up somehow. You could, for example, hint at the woman being into black magic or maybe not being human at all.
Also, there are some typos and awkward sentences, that can easily be weeded out, if you read through it again.
The script felt overwritten in some places. You tell us something, and then kind of repeat it right after:"He takes a tray out from the inside of it and there's two burnt to a crisp pieces of ham. They're ruined".
- If the ham's burnt to a crisp, I'm pretty sure it's ruined "It's all too much for him. ...he tries and fails to make sense of it all."
- Again sort of the same idea written twice.
And when Edward is on the phone, he mentions some things to Steven, and then just repeats them in the next scene ("I want to leave them enough money" & "Well here I am"
But I must say, that I really like the idea of an overwhelmed father changing his attitude after he comes face to face with something supernatural. There's definitely some potential there!
