That’s a very good question
Great ending.
So much or what happens here is in the minds of the characters. Nothing creepy really happens (although they do tumble through the floor), but we hold our breaths along with the characters. Is it a bear? We never see the bear. There is someone digging under the house. OK, is it a ghoul? No that we ever find out.
Effective tease of your readers here. Skillfully played. You are in control all the while. BTW: great dialogue.
Happy Halloween 😃
Thank you for your caring words, dear heart!
