Metal Detector Maniac

See that man in the distance? The guy who has been using his metal detector to investigate the same patch of grass in this public park for over an hour? Is he a peaceful hobbyist, searching for historical artifacts? Or, is he some sort of devious maniac, hiding in plain sight, waiting for an opportunity to prey upon the innocent? When Matt Farley and Tom Scalzo, music professors currently on sabbatical, spot this man, they become immediately suspicious. Given Tom's highly sensitive "vibe receptors," these suspicions carry significant weight. Fearing their sleepy bedroom community to be in jeopardy, our heroes have little choice but to reinvent themselves as citizen sleuths and dive headlong into a full investigation.
