Atom Boy — Ray Cummings

Retired and rusticating Pete McLean, former policeman, sees something new in crime-fighting in a rural setting! Note: short story

excerpt
My name's Pete McLean, and I've been mixed up in a few gunfights in my time as a member of the police force in a big city. But when a fellow gets to be seventy, even though he's still hale and hearty, the idea of taking things easy is pretty attractive.
So I retired and brought my granddaughter Effie along to this quiet little Vermont place. Effie, who is twenty-three, was married at twenty, and after about a year she had to call it quits. After her divorce, she came back to me; so she was in the mood, too, for peace and quiet.
You can rusticate grand up here with the Green Mountains all around. If that's what you want. It came hard for me, at first. You know, the captain of a precinct in a big city gets used to action.
The nearest village is Hewlett Corners, hidden from us behind a hill. There's nothing here but woods, a field, a brook, and an undulating white stretch of highway with our little house beside it. It didn't take me long to discover that farming wasn't in my line. I had to do something, so this being one of the main highways through Rutland, I put in a little gas station. The new cars were all coming in now; there was quite a bit of traffic and I did nicely.
