Archie's Girls Betty and Veronica #79

When Betty dates Archie, Veronica loans her a brooch to wear. With Veronica's usual ulterior motive, the borrowed brooch transmits a radio signal so that Veronica can keep an eye on the pair. When a cape with the brooch blows out of Archie's jalopy and is grabbed by a playful hound, Veronica has to follow the signal through some less-than-desirable places.
