Outside Millbrook, New York, just past the county line, the Sunoco on Route 9 stays open all night. The kind of place you stop at when you're the only car on the road, when the gas gauge hovers near empty and the radio has faded to nothing but static. I worked the graveyard shift there one autumn, between October and November, when the leaves were gone and the cold came down from the mountains like a hand on the back of your neck. The night it happened was a Tuesday, or maybe a Wednesday — the days all blurred together — and the only customer I saw before midnight was a woman in a blue sedan who bought a pack of mints and said nothing. After that, the phone rang. And it kept ringing. Not a wrong number. Not a prank. Just a voice on the other end, asking the same question, every time I picked up. This is the story of that night, and why I don't drive past that Sunoco anymore, even in daylight, even when the tank reads empty.
