Flash Prompt – Love Letter Mystery



Let’s do a writing warm-up or a little daydream fuel, if you’re more reader than writer.


You’re walking to your car after work. It’s late. The air smells like rain, and the world feels unusually quiet. You unlock the door, toss your bag inside and that’s when you see it.


A small envelope, tucked under your windshield wiper.

Your name is written on the front.

Inside, one line:

“I’ve seen the way you smile when you think no one’s watching. That’s how I knew it had to be you.”

No return address. No signature. Just those words and a strange little thrill in your chest.


Now what?


Do you crumple it up and pretend it didn’t happen?

Or go back inside and scan every face in the office, wondering who’s been paying that much attention?

Or maybe you keep it.

Put it in your nightstand.

And start hoping for the next one.


Use this as a writing prompt, a story starter, or just something to spark a fantasy. And if you feel brave—drop the next linein the comments. What does the second letter say? What happens when they’re finally caught?
