Foreshadowing

What is happening right now in my story is that Sal is telling her grand parents the story about Phoebe. In her story she explains how Phoebe feels about a woman named Mrs.Partridge who is blind but can guess people's age. Phoebe also makes Sal feel a bit scared or intimidated by Margaret by telling her "Her name is Mrs.Cadaver right? Have you ever wondered what happened to Mr.Cadaver". These are a few reasons why I think some of the stuff that might happen later on in my story will be that Sal ends up learning that Margaret did something horrible to her husband to get him out of her life. So she might try to worn her father about it but her father won't listen no and whatever happened to Mr.Cadaver will also happen to him.
