Chapter Four: The Last Picture Show

"It's been a week since the discovery of Jason Blossom's body. But his death would not be the first, nor would it be the last casualty that the town of Riverdale would suffer. The Twilight Drive-In, where I work; my home away from home. A piece of town history is closing for good, just when we needed a place to escape to the most. With Sheriff Keller knocking on every door, and neighbor suspecting neighbor, every day that passes is becoming more like Salem during the witch trials. And meanwhile, the girl next door, our friendly neighborhood Hitchcock blonde, Betty Cooper, was wrestling with the knowledge that her best friend Archie Andrews was caught up in a forbidden romance."

- Jughead Jones
