What if every clue points in the wrong direction? Friday Barnes has been deported to Switzerland! With their in - school detective gone, Highcrest Academy has descended into chaos. Someone's fired all the teachers! The Headmaster claims it wasn't him, and suspicion soon turns to Ian Wainscott, but Friday won't stand by and let her favourite nemesis take the blame. Apart from being innocent (probably), he's seriously good - looking. There's also the problem of the new vice principal and his questionable teaching methods. It's hard to take someone seriously when they wear tie - dyed t - shirts. Can Friday save Ian's scholarship? Can she find the prankster before they bring down the school? Can she run the cross country? She's certainly going to try . . . to do the first two, anyway.
