When the neighbors on a suburban street compare notes on what might be happening, a teenager says he read a story about aliens who take over earth by first sending spies who look like humans to live among us.

"The Monsters Are Due on Maple Street" aired in 1960 as part of the first season of The Twilight Zone. Many episodes are scary.

If we re-wrote this to include social media, we would have a story from today's news reports.
