In “Bad Man on Campus,” Linc, Julie and Pete go undercover at a high school to find out why a popular teacher ended up dead under a pier. No, they’re not going to fink on kids! Come on! They want to find out who the adults who are using the kids for their own criminal purposes are.

One groovy highlight: Linc, undercover as a history teacher, gets some very racist blowback from the kids in class, particularly the trouble-making ringleader. He finally blows his cool, saying to the kid with steely anger: “Hey, now that’s a big mouth, friend. How would you like me to come down and put my foot in it?”

Solid, Linc!
