Profe a la fuga (El club de las malas ideas, 2)

When a new teacher arrives at school, he quickly becomes the idol of all the students. Roldán tells the best jokes, knows how to skydive, and has traveled the world having countless adventures. He's practically a hero! Or so most people think. The Bad Ideas Club isn't so sure. What's such a cool guy doing at a school like theirs? Something's fishy here; Roldán must be hiding a secret identity. Is he a spy? A thief? Or an alien from outer space sent to invade Earth? Okay, the last one seems a bit unlikely, but… who knows? The point is, the Bad Ideas Club is determined to uncover the truth, even if it means turning the whole school upside down!
