This is the direction we'd recommend.
The narrator isn't an action hero. He's an ordinary bloke who's hot, tired and beginning to wonder whether the view was really worth turning himself into a wet dish cloth for.
He gets back from the walk thinking about a cold drink and a shower.
Someone is standing beside his car.
A man he's never seen before.
The stranger knows his name.
More troublingly, he asks:
"Did you find it?"
The narrator has absolutely no idea what he's talking about.
At least, not yet.
Potential: Mystery/thriller/adventure with humour.
