The Impossible Clue by Sarah Rubin

3.0

Solving mysteries are really just like solving puzzles: something that Alice Jones is really good at and loved to do. No wonder the kids at her school say she's the best at solving mysteries. When a classmate literally has her dragged into a mystery happening at his dad's science lab, Alice is reluctant to help at first. But a scientist gone missing in the middle of supposedly developing an invisibility suit? It's too intriguing to pass up, especially for Alice who lives and breathes science and math. Could a competing science lab have something to do with the mysterious disappearance? Did Dr. Learner run away? Or did someone take him?

This is a great choice for science-minded kids who like a mystery story and it's especially nice to see a girl in that scientific role. Alice is a little like Encyclopedia Brown: super smart with a great memory and very thorough.
