I’ve always been an avid reader, and as a kid in the 80s I devoured YA/Children’s short horror fiction anthologies by the dozen (obviously, Alvin Schwartz’s SCARY STORIES TO TELL IN THE DARK were at the top of the list!) I still have a handful of them, but I’m trying to track down one in particular. There’s a chance it came from a Scholastic book fair… I can’t remember any of the other stories in this particular volume, but the tale forever etched in my brain was about a pair of brothers left with a sitter for the evening while their parents went out. The younger brother, the story’s protagonist, notices a light come on in their backyard shed. He is terrified for some reason, and alerts everyone else. One by one the sitter, the sitter’s boyfriend (I think), the older brother, and, after their return, the kid’s parents all stick their heads out the window to look and are pulled off into the night. I believe the story ends with the kid sitting alone in the house, staring at the window.
I’d kill to know what this one is. I’ve been looking for years!
