Story with an twist (300 words)​
aleksklad [387]

Answer:

Mysterious Stranger

Prompt: Write a story that includes the words sunscreen, camera, and tourist.

He really did look like a tourist, with a camera around his neck and a bottle of sunscreen sticking out of his tote bag.

The portly man sat on the terrace, sipping lemonade and pretending to look at a glossy cruise brochure. His sunglasses masked his eyes, but I knew he wasn't looking at the brochure: he hadn't turned a page for the last ten minutes.

As I brought him his clam chowder, he coughed up a "thank you" and looked at me briefly. I tried not to stare at the tiny scar across his left eyebrow.

I walked back inside with my empty tray, shaking my head. He looked familiar, but I couldn't quite place him.
