Cameron is so excited about the upcoming science fair. He can’t wait to be in fifth grade so that he can participate and maybe win the trophy back to his school for another year. The only thing more exciting is solving mysteries like his dad. But it’s no mystery why Cameron is always losing and forgetting things – it’s not easy shuffling between two houses each week now that his mom is back in Austin, Texas. Cameron’s spent so much time staring at the trophy in the display case, now it’s up to him and his three best friends to figure out where the trophy disappeared to!
