4. Intergalactic Ketchup (Bryony Brownwell's Mystery Project)

Episode 4: Headmaster Crump’s decided we’re putting on a school play. It’s all about a diner in outer space, where aliens link up and eat fast food (yeah, bonkers, right?!) And Bryony was hoping to get the main part. But instead, she’s been cast as a waitress alongside dippy Xandria Lemon. What a joke. Bryony is not impressed. But when she hears strange bleepy noises emanating from the school library and discovers a small puddle of glittery gloop in the main hall, Bryony begins to suspect there’s a real alien hiding amongst them…!
