Betty and Veronica #85

In "Mad Fad," the high school's temperamental computerized furnace goes haywire, leaving even Mr. Svenson stumped. With the heat failing and winter looming, Dilton Doiley is called in to diagnose the glitch—only to find himself knee-deep in a mystery that might just be a little too smart for its own good. Written by George Gladir and illustrated by Dan DeCarlo, with inks by Rudy Lapick, colors by Barry Grossman, and letters by Bill Yoshida, this 1995 classic features a cover by Dan DeCarlo and Alison Flood.
